tracking faster web bundlers' issues

evanw/esbuild

Pros

• No boilerplate for transforming/bundling javascript files - just esbuild something.js --bundle --outfile=/path/to/out.js and that's it
• Has IIFE output option

Cons

• "No boilerplate" doesn't mean its output is correct
  • Mostly incorrect for common project, so minor tweakings may be needed
• No supports for:
  • modifying AST (which means babel-like plugin system)
  • hot module reloading
  • These are officially non-goal for esbuild
• No HTML entry point, or regular text file output
• Minifier isn't that good; have to pass into Terser once after esbuild minify
• Doesn't care about preserving comments

swc-project/swc

Pros

• Plugins can play with AST
  • Still in beta, but they say it won't gonna change far away

Cons

• Transforming a single file needs lots of .swcrc boilerplate
• No IIFE output options
• Bundling isn't ready
  • No output entries support except javascript
    • Seems there is CSS or something but undocumented
  • Does not minify during bundling files
  • Sourcemap output is absolute path, not relative to project root

microsoft/TypeScript

Cons

• Why are you using this with hoping fast and sane build results kthx gotta sleep gnight
