@cerisier Unfortunately the parcel upgrade, as it always does, introduces some changes that create a bunch of pain.

I can't land this yet because scripts/build-release.sh currently fails like so:

+ node_modules/.bin/parcel build assets/index.html --no-cache --dist-dir /Users/jlfwong/code/speedscope/dist/release --public-url ./ --detailed-report
🚨 Build failed.

@parcel/core: Failed to resolve 'preact' from './src/speedscope.tsx'

  /Users/jlfwong/code/speedscope/src/speedscope.tsx:1:25
  > 1 | import {h, render} from 'preact'
  >   |                         ^^^^^^^^
    2 | import {ApplicationContainer} from './views/application-container'
    3 | import {ThemeProvider} from './views/themes/theme'

@parcel/resolver-default: External dependency "preact" is not declared in package.json.

  /Users/jlfwong/code/speedscope/package.json:79:3
    78 |   },
  > 79 |   "dependencies": {
  >    |   ^^^^^^^^^^^^^^
    80 |     "open": "7.2.0"
    81 |   }

Accepting the suggestion would probably fix this bug, but it introduces an IMO unacceptable tradeoff -- it makes the speedscope npm package take on dependencies that are totally unneeded because it doesn't import them at all. This bloats what happens when people run npm install speedscope. The dependencies as listed are correct.

One solution for this is create a totally separate package.json for the CLI published through npm than I use for defining main project dependencies.

An alternative solution would be to complete the work I started in #295 and drop this annoying dependency entirely. I'm going to sleep on it and decide what to do later.

That's very unfortunate :( Especially since parcel is a bundler...
I wonder if bundledDependencies isn't made for this usecase, since you're bundling preact.
Maybe worth opening an issue on parcel.
