The plugin doesn't seem to be doing anything #84
Description
I'm not able to run anything needing transpilation even with the most basic configuration - attempt to run something ends with syntax error on node_modules/systemjs/dist/system.src.js:2823:8; when I try to log source param of the getSource function on this line I'm getting untranspiled code.
index.html (only the relevant part):
<script src="node_modules/promise-polyfill/promise.js"></script>
<script src="node_modules/systemjs/dist/system.src.js"></script>
<script src="system.config.js"></script>
<script>
SystemJS.import('index.js');
</script>
system.config.js:
SystemJS.config({
map: {
'plugin-babel': 'node_modules/systemjs-plugin-babel/plugin-babel.js',
'systemjs-babel-build': 'node_modules/systemjs-plugin-babel/systemjs-babel-browser.js'
},
transpiler: 'plugin-babel'
});
(Adding baseURL, defaultJSExtension won't help)
index.js
setTimeout(() => {
console.log('Hello from es6!');
}, 0);
Exact stack trace:
SyntaxError: Wrong syntax

(Don't have any other old browser than IE11, sorry. Also tried to include various core-js polyfills.)
Am I missing something obvious?

By default SystemJS won't transpile all code, only code it deems to be ES module code.
Try adding:
Or just specifically for the

This works, thanks!
Do I get it right that's what the following note in
systemjs/doc/module-format.mdstates?(I thought about adding a feature detection clarification in the plugin's readme.)

Yes exactly, if you'd like to clarify PR's welcome.
