Can I replace webpack with bun?

[austere cloud]

Its mentioned that bun is faster than webpack, but I haven't been able to find any guides on how to replace webpack with bun IN AN EXISTING PROJECT

I have inherited a semi complicated project that uses webpack for dev and production, and both are importing a shared base file

It's so slow when I run it in the CI I wanna cry, and bun seems like a great solution, but I simply failed to try and recreate the webpack logic using bun

Is there some official guide that explains how to integrate bun into an existing project? Would it help if I pasted the webpack configs here?

Thanks

It's a totally new bundler with a different plugin API - Bun doesn't try to be Webpack-compatible

So the answer is "yes" but it would require a full migration

@karmic vale I'm down for a complete migration, but does bun support everything I need? I'll paste the web pack configs if that's relevant:

webpack.devserver.js:

const {merge} = require('webpack-merge');
const {BundleAnalyzerPlugin} = require('webpack-bundle-analyzer');
const FaviconsWebpackPlugin = require('favicons-webpack-plugin');
const {common} = require('./webpack.common');

const plugins = [new FaviconsWebpackPlugin('../src/assets/logo/favicon_red.png')];
if (process.env.ANALYZE) {
    console.log('Running BundleAnalyzerPlugin');
    plugins.push(new BundleAnalyzerPlugin());
}

module.exports = merge(common, {
    entry: ['./index.js'],
    mode: 'development',
    devtool: 'source-map',
    plugins,
});

I can't send the common config file for some reason, discord limits the char count

Bump, since I need to make the decision soon

You’re using a very basic webpack config. Just make the switch

[austere cloud]

I failed doing it by myself, is there any migration guide?

Note that There's the imported common config

[paper birch]

show the failure

whats your error

[karmic vale]

Most of these plugins don't have equivalents yet in Bun

and I'm guessing there are many more in common

[austere cloud]

So the answer is basically no then... will there be equivalents for bun? Is replacing webpack on your roadmap or is it low on the checklist?

Alternatively, will\is there an equivalent plugin system for the build? (So that people could implement those webpack plugins into bun)

[karmic vale]

We're not trying to be a drop-in replacement. Bun's bundler takes more cues from esbuild, and we're aiming to be compatible with all esbuild plugins

Webpack's plugin system has some systemic performance issues

But some sort of adapter isn't out of the question

But it's not a high priority
