renova v0.1.0

Overview

renova patches third-party packages with non-fully-ESM-compliant source and/or TypeScript declaration files (e.g. @apollo/client) by appending explicit file names and extensions to unqualified export and import statements, facilitating nodenext/node16+ module resolution of dependencies with legacy exports.

For example, given the following source tree:

• directory/
  • index.js
• file.js

Unqualified exports and imports are corrected as follows:

Input

export {foo} from './directory';
import bar from './file';

Output

export {foo} from './directory/index.js';
import bar from './file.js';

Usage

Automatic

📍 package.json

{
  "scripts": {
    "dependencies": "renova @apollo/client"
  }
}

This will patch @apollo/client's .d.ts files whenever dependencies are installed or upgraded.

💡 Note that, when run from the dependencies lifecycle script, no output may be printed. In contrast, postinstall does allow output but is only executed when installing all dependencies; not when installing or upgrading one or more specific packages.

Manual

$ npx renova [--dry-run] [--extensions=<extension>,...] [--verbose] <package> ...

    <package>: Name of a package under ./node_modules to patch, e.g. '@apollo/client'.

    --dry-run: Print potential outcome without altering files. Implies --verbose.
 --extensions: Comma-separated list of file name extensions to process. Defaults to '.d.ts'.
    --verbose: Print all matching exports and imports.

Example

# first-time run
$ npx renova --verbose @apollo/client
./node_modules/@apollo/client/cache/core/cache.d.ts
         🛠️ ../../utilities → ../../utilities/index.js
         🛠️ ./types/DataProxy → ./types/DataProxy.js
         🛠️ ./types/Cache → ./types/Cache.js
...

# safe to run on an already-patched package
$ npx renova --verbose @apollo/client
./node_modules/@apollo/client/cache/core/cache.d.ts
         ✔️ ../../utilities/index.js
         ✔️ ./types/DataProxy.js
         ✔️ ./types/Cache.js
