A development tool to run typescript from node modules on-the-fly.
This is useful for developing with locally linked modules, typically in a monorepo setup.
- npm packages expected to publish with full TypeScript source code and source maps data.
- A require hook that checks the code being required for source map
- If source map exist, load it and look for source file
- If source files exist, then load and transpile them on the fly.
- Otherwise just return original code.
- npm package does not need to provide transpiled code
package.jsonneeds to provide configuration that tells run-ts the mapping of src dir to dist dir- When run-ts can't find the actual required file, it will check
package.json- if it finds config for it, it will map filename to original source
- it will load the source and transform it
