Standard package.json key for .ts files

A common TypeScript module structure looks like this:

src/index.ts
dist/index.js
dist/index.d.ts

and a package.json that looks like this:

  "main": "dist/index.js",
  "types": "dist/index.d.ts",

There's a convention to use the package.json key jsnext:main to point to a variant of main that uses ES2015 module syntax. Can we develop a similar convention to point at .ts files, e.g. typescript:main?

Consider a TypeScript project that is sharded across many microlibraries (e.g. my-project-core, my-project-thing-plugin, my-project-other-thing-plugin). I'd like to be able to configure my bundler to import from src/*.ts files for any module whose name starts with my-project. Otherwise, it will be looking in dist/*.js and I'll have to rebuild the plugins any time I make changes in them.

Of course, I could use jsnext:main for this purpose now, but any consumers who aren't using TypeScript would get syntax errors for any files that contained TS-specific syntax like types. Similarly, I could make up my own package.json key and configure my bundler to look there first, but it behooves the community to have a convention here. That will allow bundlers like Webpack, Browserify, Rollup, and Pundle to look in the right place by default.

Esamina le voci di package.json mostrate nell’issue, in particolare main, types e jsnext:main, quindi confronta il modo in cui Webpack e Rollup risolvono i punti di ingresso dei pacchetti. Verifica se una convenzione specifica per TypeScript dispone del supporto della community o dei bundler; il lavoro è considerato completato quando il design e il percorso di adozione della convenzione sono chiaramente definiti.
