bun.js size and memory usage

[vjpr]

When thinking about using Bun as a desktop replacement over Electron (#790), I am wondering how it compares to Node.js in terms of download size and also memory usage.

Download size

bun v0.1.4 = 37MB uncompressed / 12.5MB compressed
node v18.6.0 = 86.5MB uncompressed / 29.3MB compressed

Does bun have a production-only build that could be even slimmer?

Memory usage

I guess we only need to look at JSC vs V8 for this.

Well, this doesn't look promising 😅

$ bun -v && du -h $(which bun)

$ node -v && du -h $(which node)
