build status

This is a TypeScript AST Transformer that allows you to rewrite import path in output JS & d.ts files accordingly. The primary use case for this is to mitigate different build system import structure, such as relative vs absolute import and aliasing output import paths.

Usage

ttypescript

Example for ttypescript usage is in examples/ttypescript. Run npx ttsc.

Compiler Wrapper

First of all, you need some level of familiarity with the TypeScript Compiler API.

compile.ts & tests should have examples of how this works. The available options are:

projectBaseDir: string

This is the base directory of your project folder. This is primarily used to determine the correct path when rewriting relative import to absolute import.

project?: string

Project name to rewrite relative import to. For example:

import foo from './foo'
// Becomes
import foo from 'my-project-name/foo'

rewrite?(importPath: string, sourceFilePath: string): string

Custom rewrite function to rewrite any import path we encounter to any new import path.

alias?: Record<string, string>

Alias regex map to replace, e.g:

{
    "^(foo)$": "external/$1"
}
