Concept of Project Setup

[frank-dspeed]

Typescript is in general great but needs a lot of configuration from the user see microsoft/TypeScript#33136

creating a tool that does the includes composit d.ts creation as also showing the current state of your deps is getting more and more importent.

• check and create d.ts from js
• check typescript resolve modes if they will find types. and list exportConditions if needed.
• create rollup-plugins/strip-none-type-comments.
• create rollup-plugins/detect-none-type-comments.
• create rollup-plugins/detect-type-comments.
• create JSDOC Type Annotations from .d.ts + JS

Your Typescript project can only have a single resolve algo for its Modules and Types this is contra productiv.

other solution

{
  "[compilerOptions](https://www.typescriptlang.org/tsconfig#compilerOptions)": {
    "[baseUrl](https://www.typescriptlang.org/tsconfig#baseUrl)": "src",
    "[paths](https://www.typescriptlang.org/tsconfig#paths)": {
        "app/*": ["app/*"],
        "config/*": ["app/_config/*"],
        "environment/*": ["environments/*"],
        "shared/*": ["app/_shared/*"],
        "helpers/*": ["helpers/*"],
        "tests/*": ["tests/*"]
    },
}

today the best solution will be the project references in tsconfig and the composit flag in the dist code of the package.

lookup files

• package.json
• tsconfig.json
• jsconfig.json

stealify will not use a json it will use a js file as entry that will gen a importMap based on all files and will cache that as json if requested.

Best solution

We get full access to the typescript ast while we can not change it which is also not needed for our case we want to give type hints and expose resolve algos.

• https://github.com/Microsoft/TypeScript/wiki/Writing-a-Language-Service-Plugin

we use the typescript ast as file emitter for rollup and then return the results and information.
