Allow pnpm to be run programmatically

[vjpr]

Programmatic CLI API

I want to do:

import pnpm from 'pnpm'
await pnpm(inputArgs)

Currently pnpm/package.json has:

  "exports": {
    ".": "./package.json"
  },

What is this needed for? It doesn't match with "main": "bin/pnpm.cjs",.

Should also migrate it to ESM.

Programmatic lower-level API

I'd also like to be able to have a lower-level api so I don't have to parse cli flags, but can call methods.

E.g. I'd like to be able to do:

import Pnpm from 'pnpm'
const pnpm = new Pnpm
pnpm.addReporter('json', (line) => { fs.appendFileSync('pnpm.log', line) } )
pnpm.on('warning', (line) => { fs.appendFileSync('pnpm-warnings.log', line) } )
await pnpm.install()

This would be a lot cleaner.

Plugin architecture

Might also be interesting to look at how webpack's plugin system tapable works. It provides a ton of flexibility for hooking into the package manager. Although I do find it a bit complex at times and lacking documentation.

Any update on this?

Can this be done:

import pnpm from 'pnpm'
await pnpm.install({cwd: process.cwd()})
