API
babel([options])
Initialize a duo plugin. Available options
:
extensions
a list of file extensions that should be transpiled (default:['.js', '.jsx', '.es', '.es6']
)onlyLocals
specify that any remotes should not be transpiledonly
a list of glob patterns to only transpileignore
a list of glob patterns to not transpile (the opposite ofonly
)- anything else is passed directly to babel
Selective Transpiling
In many cases, onlyLocals
is needed early on. Your local scripts need to be
transpiled, but most of your dependencies don't need it. However, as time goes
on and you publish your own dependencies using ES6, you'll need something more
selective.
You can add an array as either only
or ignore
(not both) to selectively
enable babel's transpilation.
Your patterns should match the directory structure that duo uses. (and that you can see on disk)
lib/**.js
will match any JS file in the local lib dircomponents/lodash-lodash@*/**.js
will match any version of lodashcomponents/component-*/**.js
will match anything in the component organization.
Source Maps
ES6 source-maps are turned on automatically when duo has enabled source-maps,
this feature can be disabled by explicitly setting the sourceMaps
option.
