Partial builds with NPM package?

I’m using Webpack now and I’m wondering if something like “custom builds” is possible when using NPM version of the package. Since Bluebird is already modularized, it would be nice if there was some way of excluding features I’m not using.

For now I’ll fork it and do

require('./timers.js')(Promise,INTERNAL);
// require('./any.js')(Promise,Promise$_CreatePromiseArray,PromiseArray);
// require('./race.js')(Promise,INTERNAL);
require('./call_get.js')(Promise);
// require('./filter.js')(Promise,Promise$_CreatePromiseArray,PromiseArray,apiRejection);
// require('./generators.js')(Promise,apiRejection,INTERNAL);
// require('./map.js')(Promise,PromiseArray,INTERNAL,apiRejection);
// require('./nodeify.js')(Promise);
// require('./promisify.js')(Promise,INTERNAL);
// require('./props.js')(Promise,PromiseArray);
// require('./reduce.js')(Promise,Promise$_CreatePromiseArray,PromiseArray,apiRejection,INTERNAL);
// require('./settle.js')(Promise,Promise$_CreatePromiseArray,PromiseArray);
// require('./some.js')(Promise,Promise$_CreatePromiseArray,PromiseArray,apiRejection);
require('./progress.js')(Promise,isPromiseArrayProxy);
require('./cancel.js')(Promise,INTERNAL);

but it would be cool to have a better solution.

Edit: Oh wait, I can’t fork it and edit since this is generated.

For my specific use case, I’m only using Bluebird because I want long stack traces. So I’m not totally confident which files I could potentially include and exclude, since I’m not too familiar with the source code, but I omitted the files suggested above.

Just an update that we’re working with v8 to have long stack traces in production by default for native promises. My approach (personally) over the last few years has been to try and improve the native promises situation.

That said - you can always just run the partial build (with the build tool) and require that.

v3.5.1 (latest) actually ships the core (partial) build to NPM-- no building necessary. Switched to that, and shaved off a few kb’s. Thanks.
