Introduction

The Files.com Java client library provides convenient access to the Files.com API from JVM based applications.

Installation

Maven

A maven jar is available through maven-central. To use the package add the following to your pom.xml file.

<dependency>
    <groupId>com.files</groupId>
    <artifactId>files-sdk</artifactId>
</dependency>

Gradle

To add the dependency to your Gradle project add this to your

compile group: 'com.files', name: 'files-sdk'

Requirements

The Files.com Java SDK supports all versions of Java beginning with Java 8 (Also known as 1.8).

Files.com is Committed to Java

Java is a core language used by the Files.com team for internal development. This library is directly used by our official Boomi integration and our official MuleSoft integration.

As such, this library is actively developed and should be expected to be highly performant.

Explore the files-sdk-java code on GitHub.

Getting Support

The Files.com Support team provides official support for all of our official Files.com integration tools.

To initiate a support conversation, you can send an Authenticated Support Request or simply send an E-Mail to support@files.com.

Authentication

There are two ways to authenticate: API Key authentication and Session-based authentication.

Authenticate with an API Key

Authenticating with an API key is the recommended authentication method for most scenarios, and is the method used in the examples on this site.

To use an API Key, first generate an API key from the web interface or via the API or an SDK.

Note that when using a user-specific API key, if the user is an administrator, you will have full access to the entire API. If the user is not an administrator, you will only be able to access files that user can access, and no access will be granted to site administration functions in the API.

import com.files.FilesClient;
import com.files.exceptions.*;
import com.files.exceptions.ApiErrorException.*;
import com.files.models.User;
import java.util.HashMap;

FilesClient.apiKey = "YOUR_API_KEY";

try {
  // Alternatively, you can specify the API key on a per-object basis in options HashMap to a model constructor.
  HashMap<String, Object> requestOptions = new HashMap<>();
  requestOptions.put("api_key", "my-key");
  User user = new User(params, requestOptions);

  // You may also specify the API key on a per-request basis in the final parameter to static methods.
  HashMap<String, Object> requestOptions = new HashMap<>();
  requestOptions.put("api_key", "my-key");
  User.find(id, params, requestOptions);
} catch (NotAuthenticatedException e) {
  System.out.println("Authentication Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
} catch (SdkException e) {
  System.out.println("Unknown Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
}

Don't forget to replace the placeholder, YOUR_API_KEY, with your actual API key.

Authenticate with a Session

You can also authenticate by creating a user session using the username and password of an active user. If the user is an administrator, the session will have full access to all capabilities of Files.com. Sessions created from regular user accounts will only be able to access files that user can access, and no access will be granted to site administration functions.

Sessions use the exact same session timeout settings as web interface sessions. When a session times out, simply create a new session and resume where you left off. This process is not automatically handled by our SDKs because we do not want to store password information in memory without your explicit consent.

Logging In

To create a session, the create method is called on the Session object with the user's username and password.

This returns a session object that can be used to authenticate SDK method calls.

import com.files.exceptions.*;
import com.files.exceptions.ApiErrorException.*;
import com.files.models.Session;
import java.util.HashMap;

HashMap<String, Object> sessionParameters = new HashMap<>()
sessionParameters.put("username", "username");
sessionParameters.put("password", "password");

try {
  Session session = Session.create(parameters);
} catch (NotAuthenticatedException e) {
  System.out.println("Authentication Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
} catch (SdkException e) {
  System.out.println("Unknown Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
}

Using a Session

Once a session has been created, you can store the session globally, use the session per object, or use the session per request to authenticate SDK operations.

import com.files.FilesClient;
import com.files.exceptions.*;
import com.files.exceptions.ApiErrorException.*;
import com.files.models.User;
import java.util.HashMap;

// You may set the returned session to be used by default for subsequent requests.
FilesClient.session = session;

try {
  // Alternatively, you can specify the session ID on a per-object basis in the second parameter to a model constructor.
  HashMap<String, Object> requestOptions = new HashMap<>();
  requestOptions.put("session_id", session.getId());
  user = new User(params, requestOptions);

  // You may also specify the session ID on a per-request basis in the final parameter to static methods.
  HashMap<String, Object> requestOptions = new HashMap<>();
  requestOptions.put("session_id", session.getId());
  User.find(id, params, requestOptions);
} catch (NotAuthenticatedException e) {
  System.out.println("Authentication Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
} catch (SdkException e) {
  System.out.println("Unknown Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
}

Logging Out

User sessions can be ended calling the destroy method on the session object.

import com.files.exceptions.*;
import com.files.exceptions.ApiErrorException.*;

try {
  session.destroy();
} catch (NotAuthenticatedException e) {
  System.out.println("Authentication Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
} catch (SdkException e) {
  System.out.println("Unknown Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
}

Configuration

Configuration is performed by calling FilesClient.setProperty().

Configuration Options

Base URL

Set this to the full https:// URL of your Files.com subdomain (e.g. https://MY-SUBDOMAIN.files.com). This is not required in most cases, but one benefit of setting it is that it ensures that authentication failures will be logged to your site's API logs. Without setting this, we won't know which site to associate the authentication failure with, and it won't be logged to your site's API logs. This is always required if your site is configured to disable global acceleration. This can also be set to use a mock server in development or CI.

import com.files.FilesClient;

FilesClient.setProperty("apiRoot", "https://MY-SUBDOMAIN.files.com");

Logging

The Files.com SDK is compatible with the standard log4j logging scheme.

Add com.files logger to your Loggers root in the log4j2.xml file.

<Loggers>
    <!-- set preferred level -->
    <Logger name="com.files" level="TRACE" />
    <!-- to enable network request -->
    <Logger name="okhttp3.logging.wire" level="INFO"/>
</Loggers>

Create a resources/log4j2.xml file.

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
        </Console>
    </Appenders>
    <Loggers>
        <!-- set preferred level -->
        <Logger name="com.files" level="TRACE"/>
        <!-- to enable network request -->
        <Logger name="okhttp3.logging.wire" level="INFO"/>
    </Loggers>
</Configuration>

You can read more about log4j2 configuration.

Sort and Filter

Several of the Files.com API resources have list operations that return multiple instances of the resource. The List operations can be sorted and filtered.

Sorting

To sort the returned data, pass in the sort_by method argument.

Each resource supports a unique set of valid sort fields and can only be sorted by one field at a time.

The argument value is a Java HashMap<String, Object> object that has a property of the resource field name sort on and a value of either "asc" or "desc" to specify the sort order.

Special note about the List Folder Endpoint

For historical reasons, and to maintain compatibility with a variety of other cloud-based MFT and EFSS services, Folders will always be listed before Files when listing a Folder. This applies regardless of the sorting parameters you provide. These will be used, after the initial sort application of Folders before Files.

import com.files.ListIterator;
import com.files.exceptions.*;
import com.files.exceptions.ApiErrorException.*;
import com.files.models.User;
import java.util.HashMap;

// users sorted by username
HashMap<String, Object> args = new HashMap<>();
HashMap<String, Object> sortArgs = new HashMap<>();
sortArgs.put("username", "asc");
args.put("sort_by", sortArgs);

try {
  ListIterator<User> users = User.list(args);
  for (User user : users.listAutoPaging()) {
    // Operate on user
    System.out.println(user.username);
  }
} catch (NotAuthenticatedException e) {
  System.out.println("Authentication Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
} catch (SdkException e) {
  System.out.println("Unknown Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
}

Filtering

Filters apply selection criteria to the underlying query that returns the results. They can be applied individually or combined with other filters, and the resulting data can be sorted by a single field.

Each resource supports a unique set of valid filter fields, filter combinations, and combinations of filters and sort fields.

The passed in argument value is a Java HashMap<String, Object> object that has a key of the resource field name to filter on and a passed in value to use in the filter comparison.

Filter Types

Filter	Type	Description
`filter`	Exact	Find resources that have an exact field value match to a passed in value. (i.e., FIELD_VALUE = PASS_IN_VALUE).
`filter_prefix`	Pattern	Find resources where the specified field is prefixed by the supplied value. This is applicable to values that are strings.
`filter_gt`	Range	Find resources that have a field value that is greater than the passed in value. (i.e., FIELD_VALUE > PASS_IN_VALUE).
`filter_gteq`	Range	Find resources that have a field value that is greater than or equal to the passed in value. (i.e., FIELD_VALUE >= PASS_IN_VALUE).
`filter_lt`	Range	Find resources that have a field value that is less than the passed in value. (i.e., FIELD_VALUE < PASS_IN_VALUE).
`filter_lteq`	Range	Find resources that have a field value that is less than or equal to the passed in value. (i.e., FIELD_VALUE <= PASS_IN_VALUE).

Paths

Files.com preserves the spelling of file and folder paths while comparing them using shared case and Unicode rules. Use the SDK comparison helpers when matching paths locally.

Capitalization

Files.com uses case-insensitive path matching based on its fixed Unicode comparison map.

For example, the following paths have the same comparison key:

Path Variant	Comparison Key
`Documents/Reports/Q1.pdf`	`documents/reports/q1.pdf`
`documents/reports/q1.PDF`	`documents/reports/q1.pdf`
`DOCUMENTS/REPORTS/Q1.PDF`	`documents/reports/q1.pdf`

This behavior applies across:

API requests
Folder and file lookup operations
Automations and workflows

See also: Case Sensitivity Documentation

The PathUtils.isSame function in the Files.com SDK is designed to help you determine if two paths on your native file system would be considered the same on Files.com. This is particularly important when handling errors related to duplicate file names and when developing tools for folder synchronization.

import com.files.util.PathUtils;

if (PathUtils.isSame("Fïłèńämê.Txt", "filename.txt")) {
    System.out.println("Paths are the same");
}

Slashes

Use / between folder and file names, without leading or trailing slashes. SDK normalization helpers convert backslashes to /, remove duplicate separators, and discard exact . and .. components. Discarding .. leaves the preceding folder name intact.

Input	Normalized path
`folder/subfolder/file.txt`	`folder/subfolder/file.txt`
`/folder/subfolder/file.txt`	`folder/subfolder/file.txt`
`folder/subfolder/file.txt/`	`folder/subfolder/file.txt`
`//folder//file.txt`	`folder/file.txt`
`folder/../file.txt`	`folder/file.txt`

Unicode and Path Comparison

Files.com compares paths using a fixed mapping shared by the server and SDKs. It treats case and many accent differences as equivalent: Résumé.txt and resume.txt identify the same file, as do q followed by a combining acute accent and q. The mapping also handles other equivalences, such as Hiragana and Katakana. Lowercasing or applying a standard Unicode normalization form alone does not reproduce these rules.

SDK comparison helpers normalize path separators and dot segments, then apply the bundled versioned comparison map. The shared examples give exact comparison results for integrations that implement their own matching. The map uses hexadecimal Unicode scalar values as keys: a missing entry preserves the character, an empty replacement removes it, and other replacements may contain several characters. Apply each replacement once without normalizing or lowercasing the result again.

Use comparison results only for matching. Send the original path spelling in API requests and preserve it for display and local filenames; comparison results can have a different spelling or length.

Trailing whitespace is significant for comparison. report.txt and report.txt are different file paths, and SDK helpers preserve spaces, tabs, and newlines. Folder names cannot end in whitespace. See Unicode Normalization for the complete path rules.

Workspaces

A Workspace groups files, users, groups, Partners, integrations, and workflows within a Files.com Site. An integration can provision a Workspace for a department or project and delegate its operation to a team without making that team Site Administrators. Every Site has a Default Workspace, with ID 0; additional Workspaces have their own IDs and root folders.

Account membership, request context, and permission grants serve different purposes. Creating an account in a Workspace determines where it belongs. Selecting a Workspace determines which resources a request operates on. A permission grant determines what the caller can do there. Selecting a Workspace never grants access to it.

Accounts and Administrative Access

A user's or group's workspace_id identifies the Workspace the account belongs to. Accounts belonging to a Custom Workspace stay within it. Default Workspace users and groups can receive permissions in one or more Custom Workspaces while keeping their existing accounts in Workspace 0.

Account	Workspace Administrator assignment	Scope
User belonging to a Custom Workspace	Set the user's `workspace_admin` to `true`.	That user's own Custom Workspace.
Default Workspace user	Create an `admin` Permission for the user on a Custom Workspace's root folder.	Each Custom Workspace with a root grant.
Default Workspace group	Create an `admin` Permission for the group on a Custom Workspace's root folder.	Every member inherits administration of each Workspace with a root grant.

workspace_admin is not a summary of a user's effective administrative access. A Default Workspace user can administer a Custom Workspace through a direct or group root grant while their workspace_admin remains false. Groups have no workspace_admin field. See Users and Groups for account fields.

An admin grant on the Custom Workspace root provides full Workspace Administrator authority over its files, users, groups, Partners, workflows, and integrations. An admin grant on a subfolder provides Folder Admin authority over that folder and its descendants; it does not provide Workspace administration. Other permission levels provide their corresponding folder access without Workspace administration. Permissions defines the levels.

Site Administrators manage cross-Workspace assignments to Default Workspace accounts. Workspace Administrators manage accounts and permissions within their own scope. Site Administrators retain access to every Workspace; adding a Workspace grant does not narrow Site Administrator authority. The product documentation explains the administrator's operational scope and site-wide controls.

Request Context and API Keys

You can include the X-Files-Workspace-Id REST header to select a Workspace for a request. SDK request options and CLI configuration send that same selection. When a Workspace is selected, Workspace-scoped resources are listed, created, and changed within that context, and ordinary paths are relative to its root.

A resource's workspace_id request field describes the resource's Workspace membership. It is separate from the SDK's Workspace request option or REST header. Creating a Workspace-scoped resource in a Custom Workspace defaults its workspace_id to the selected Workspace; a mismatching membership value is rejected with not-authorized/insufficient-permission-for-params.

Selecting another Workspace with an API key requires a Full Access key created in the Default Workspace. A user key follows that user's current access, including group permissions. A site-wide Full Access key created in the Default Workspace has Site Administrator authority in every Workspace. A Files Only key stays in its creation Workspace, even if its user has cross-Workspace access. Any key created in a Custom Workspace stays within that Workspace. Selecting another context with these confined keys is rejected with bad-request/invalid-workspace-id-header.

An account belonging to a Custom Workspace is scoped there when it authenticates normally. For a Default Workspace user, explicitly select the intended Workspace for an integration rather than relying on an interactive login preference. API Keys and Authentication cover credentials.

The Files.com Java SDK supports workspace scoping by using the FilesClient.workspaceId configuration attribute. Scope a single request by passing workspace_id in the request options.

The adjacent scoping example uses a credential authorized for the selected Workspace. A group member uses their own Full Access user key from the Default Workspace; the Site Administrator credential used to assign the grant is not needed for their day-to-day work.

import com.files.FilesClient;
import com.files.models.Folder;
import java.util.HashMap;

FilesClient.workspaceId = 123L;

HashMap<String, Object> options = new HashMap<>();
options.put("workspace_id", 456L);

Folder.listFor("/", null, options);

Delegating a Workspace to an Existing Group

An operations team already represented by a Default Workspace group can administer a Custom Workspace through one root Permission. The group and its members stay in the Default Workspace, so the same team can receive different access in other Workspaces.

First retrieve the target Workspace and Group IDs as a Site Administrator in Workspace 0. The examples use Workspace 123, group 456, and member user 789; replace them with your own IDs. Confirm that the group belongs to Workspace 0 and that the intended user is a member.

Create the Permission using a Default Workspace Full Access site-wide key or a Full Access user key belonging to a Site Administrator. Keep the request context at 0 and use the qualified root path _/Workspaces/123. Set group_id to the group's ID, permission to admin, and recursive to true. Save the returned Permission id for later removal. For an individual Default Workspace user, use user_id instead of group_id.

For a Default Workspace group, a Site Administrator can also select Workspace 123 and use an empty path to grant access to its root. The qualified path in Workspace 0 works for both Default Workspace users and groups and keeps the account scope and target Workspace explicit. Appending a subfolder to the path would grant Folder Admin access instead of Workspace Administrator authority.

After the grant, make a request as the member, using their own credential with Workspace 123 selected, such as listing that Workspace's root folder. That member can work with the Workspace's files and perform Workspace Administrator operations, such as managing its users, Partners, and integrations. A Site Administrator's successful request does not establish that the member has the intended access.

import com.files.FilesClient;
import com.files.models.Permission;
import java.util.HashMap;

FilesClient.workspaceId = 0L;
HashMap<String, Object> params = new HashMap<>();
params.put("path", "_/Workspaces/123");
params.put("group_id", 456L);
params.put("permission", "admin");
params.put("recursive", true);
HashMap<String, Object> options = new HashMap<>();
options.put("workspace_id", 0L);
Permission grant = Permission.create(params, options);
System.out.println(grant.getId());

Permission Inspection and Removal

List the member's Permissions with user_id and include_groups=true to include grants inherited through group membership. Listing only direct user grants can miss the Permission that provides Workspace administration. In Workspace 0, the Custom Workspace root appears as _/Workspaces/123; in Workspace 123, paths are relative to that root. Inspect the root path and permission=admin, rather than treating the user's workspace_admin field as their effective administrative access.

Permission lists show individual grants, rather than a single flag for effective administrative access. Membership in several groups combines their access. A Permission using group_ids instead of group_id requires membership in all the specified groups; it is not a shorthand for assigning the same grant to several independent groups.

Removing a member ends access received through that group. Deleting the root Permission ends the group's Workspace Administrator grant for every member. These changes leave independent direct and other group grants in place, so review all applicable grants when withdrawing access. Default Workspace user API keys follow those permission changes without being recreated.

Group membership maintained through SCIM follows the same rule. A Group Admin allowed to add members can give those users the group's existing Workspace Administrator access. Choose who manages the group with that authority in mind.

Delete the Permission by its returned id as the Site Administrator in Workspace 0. The removal examples use Permission ID 9001; replace it with the ID returned by your create request. Permissions are created and deleted, rather than updated in place. If narrower folder access is still needed, assign it explicitly; deleting a broad grant does not restore narrower grants it previously replaced.

HashMap<String, Object> query = new HashMap<>();
query.put("user_id", "789");
query.put("include_groups", true);
var grants = Permission.list(query, options);
Permission.delete(9001L, null, options);

Foreign Language Support

The Files.com Java SDK supports localized responses by using the FilesClient.language configuration attribute. When configured, this guides the API in selecting a preferred language for applicable response content.

Language support currently applies to select human-facing fields only, such as notification messages and error descriptions.

If the specified language is not supported or the value is omitted, the API defaults to English.

import com.files.FilesClient;

FilesClient.language = "es";

Errors

The Files.com Java SDK will return errors by raising exceptions. There are many exception classes defined in the Files SDK that correspond to specific errors.

The raised exceptions come from two categories:

SDK Exceptions - errors that originate within the SDK
API Exceptions - errors that occur due to the response from the Files.com API. These errors are grouped into common error types.

There are several types of exceptions within each category. Exception classes indicate different types of errors and are named in a fashion that describe the general premise of the originating error. More details can be found in the exception object message using the getMessage() method.

Use standard Java exception handling to detect and deal with errors. It is generally recommended to catch specific errors first, then catch the general SdkException exception as a catch-all.

import com.files.exceptions.*;
import com.files.exceptions.ApiErrorException.*;
import com.files.models.*;
import java.util.HashMap;

HashMap<String, Object> sessionParameters = new HashMap<>();
sessionParameters.put("username", "USERNAME");
sessionParameters.put("password", "BADPASSWORD");

try {
  Session session = Session.create(sessionParameters);
} catch (NotAuthenticatedException e) {
  System.out.println("Authentication Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
} catch (SdkException e) {
  System.out.println("Unknown Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
}

Error Types

SDK Errors

SDK errors are general errors that occur within the SDK code. These errors generate exceptions. Each of these exception classes inherit from a standard SdkException base class.

com.files.exceptions.ApiErrorException.ApiConnectionException ->
com.files.exceptions.SdkException ->
RuntimeException

SDK Exception Classes

Exception Class Name	Description
`ApiConnectionException`	The Files.com API cannot be reached
`AuthenticationException`	Authentication Failure on the Files.com API
`InvalidParameterException`	A passed in parameter is invalid
`InvalidResponseException`	A bad formed response came back from the API
`ServerErrorException`	The API service responded with a bad response (ie, 5xx)

API Errors

API errors are errors returned by the Files.com API. Each exception class inherits from an error group base class. The error group base class indicates a particular type of error.

com.files.exceptions.ApiErrorException.FolderAdminPermissionRequiredException ->
com.files.exceptions.ApiErrorException.NotAuthorizedException ->
com.files.exceptions.ApiErrorException ->
com.files.exceptions.SdkException ->
RuntimeException

Pagination

Certain API operations return lists of objects. When the number of objects in the list is large, the API will paginate the results.

The Files.com Java SDK provides multiple ways to paginate through lists of objects.

Automatic Pagination

The listAutoPaging function automatically paginates and loads each page into memory.

import com.files.exceptions.*;
import com.files.exceptions.ApiErrorException.*;
import com.files.models.File;
import com.files.models.Folder;

try {
  for (File item : Folder.listFor(path, null).listAutoPaging()) {
    System.out.println(item.path);
  }
} catch (NotAuthenticatedException e) {
  System.out.println("Authentication Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
} catch (SdkException e) {
  System.out.println("Unknown Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
}

Manual Pagination

The loadNextPage/hasNextPage functions allow for manual pagination and loading of each page into memory.

import com.files.ListIterator;
import com.files.exceptions.*;
import com.files.exceptions.ApiErrorException.*;
import com.files.models.File;
import com.files.models.Folder;

try {
  ListIterator<File> listing = Folder.listFor(path, null);
  do {
    for (File item : listing.loadNextPage()) {
      System.out.println(item.path);
    }
  } while (listing.hasNextPage());
} catch (NotAuthenticatedException e) {
  System.out.println("Authentication Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
} catch (SdkException e) {
  System.out.println("Unknown Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
}

Load All Items

The all function loads all items into memory.

import com.files.exceptions.*;
import com.files.exceptions.ApiErrorException.*;
import com.files.models.File;
import com.files.models.Folder;
import java.util.List;

try {
  List<File> items = Folder.listFor(path, null).all()
  for (File item : items) {
    System.out.println(item.path);
  }
} catch (NotAuthenticatedException e) {
  System.out.println("Authentication Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
} catch (SdkException e) {
  System.out.println("Unknown Error Occurred (" + e.getClass().getName() + "): " + e.getMessage());
}

Mock Server

Files.com publishes a mock Files.com API server, which is useful for testing your use of the Files.com SDKs and other direct integrations against the Files.com API in an integration test environment. It never checks credentials: send any placeholder API key, and never use real Files.com credentials with it.

The server has two modes, chosen when it starts:

Legacy mode (the default) checks required parameters and parameter types, then returns a fixed example response for each API endpoint. It does not maintain state and it does not deeply inspect your submissions for correctness, which makes it useful for testing basic network operations and JSON encoding for your SDK or API client.
Simulation mode keeps records, files and folders in memory, so a test can create, list, update and delete resources, upload a file and download the same bytes, and make chosen requests fail, stall or lose their connection on purpose. Requests it does not simulate fail with a clear error instead of returning an example response.

Start the server from its source with Ruby and Bundler. FILES_MOCK_MODE is read once at startup: leaving it unset or setting it to legacy starts legacy mode, simulation starts simulation mode, and any other value stops startup with an error. Legacy mode listens on port 4041 on all IPv4 interfaces, and simulation mode on 127.0.0.1:4041.

Simulation mode keeps its state only in the server process. Its control endpoints under /__files_mock/v1 report when the server is ready, reset it with your fixtures, add fault rules and return the journal of the requests it received. It refuses work over its limits instead of truncating it. The README in the source describes all of these, the operations it simulates and how to configure its limits.

Download the server as a Docker image via Docker Hub. The image's latest tag moves to whichever server was published last, so it need not include simulation mode; to run exactly the server the README describes, build the image from the source.

The Source Code is also available on GitHub.

bundle install

## Legacy mode
bundle exec puma

## Simulation mode
FILES_MOCK_MODE=simulation bundle exec puma
