Single entry

[ezekielchentnik]

Is there a way to limit to a single entry point?

example: /client/entry.js (rollup bundles from entry)
ignores everything else in /client

Hi @ezekielchentnik. Yep, we can use opts.patterns option:

// felt.config.js
module.exports = {
  patterns: ['entry.js']
}

Then, $ felt --src client --recipe minimal --config felt.config.js

See also https://github.com/cognitom/felt#optspatterns

---

updated: patterns is supposed to be relative from src directory.

@cognitom does not seem to work. when i specify the pattern, client/entry.js is not ran through rollup.

here is what I'm going for (I'm looking to use felt as middleware, then export if needed):

Source:

/src
    /images
        logo.png
    /components
        App.jsx
    /styles
        _partial.css
        global.css     # postcss's entry point
    entry.js           # rollup's entry point

Dist:

/dist
    /images       # entire directory copied
    entry.js      # bundle generated by rollup
    global.css    # bundle generated by postcss

@cognitom i've debugged and patterns solution works, however even when limiting by entry.js, files in sub folders are still copied, Is there a way to completely ignore a whole folder?

[ezekielchentnik]

This appears to work:

module.exports = {
  patterns: ['entry.js'],
  excludes: ['components/*.js']
}

src

/src
    /components
        App.jsx
    entry.js

dist

/dist
    entry.js

felt --config felt.config.js --src src --export dist --debug

excludes seems to be un documented. Also, I'm attempting to figure out a better pattern for all sub folders under src

[ezekielchentnik]

this pattern seems to work:

module.exports = {
   excludes: ['!entry.js', '**/']
}

[cognitom]

@ezekielchentnik perfectly right! Sorry for my misleading.
Yeah, we should add opts.exclude to the docs.

Also, I'm attempting to figure out a better pattern for all sub folders under src

I think, we could add option.ignoreUnmatchedFiles or something, but not self-explanatory...
Maybe, --no-copy option with --export could be simpler and readable. Thoughts?

[ezekielchentnik]

@cognitom an option to whitelist folders may be a better option?

i like the option of --no-copy for simple opting out.

for more complex projects, maybe adding a whitelist opts.include to make it easier for large folder structures where only a small number of folders are needed.

src:

/src
    /images
    /components
    /store
    /reducers
    /actions
    /middleware
    /constants
    /vendor
    /styles
    /utils
    entry.js

dist:

/dist
    /vendor
    /images
    global.css
    entry.js

felt.config.js

module.exports = {
  patterns: ['entry.js', 'global.css'],
  exclude:[],
  include: ['images', 'vendor'],
  handlers: {
      '.js': rollup(),
      '.css': postcss()
    }
}

Yeah, opts.includes seems popular option for this kind of tool. I like the idea. Thanks for your suggestion!
