Node.js loader for import specifiers as file paths without extensions or as directory paths
npm install specifier-resolution-node- This package intends to help experimental-specifier-resolution=node users migrate from Node.js v18 to Node.js v20 without any code change.
- Node.js v18 node --experimental-specifier-resolution=node
- Node.js v20 node --import=specifier-resolution-node/register
- This package is based on the extensionless project project, but use import-meta-resolve algorithm to get closer to the behavior of node.js 18 with --experimental-loader=specifier-resolution-node
``
npm i specifier-resolution-node
Start node with one of the following flags added. If you're running on a version of node older than 20.6.0, use:
`
--experimental-loader=specifier-resolution-node
or else, use the newer one instead:
`
--import=specifier-resolution-node/register
You can now use import specifiers as file paths without extensions or as directory paths.
By default specifier-resolution-node will try to append the following extensions: ['js', 'cjs', 'mjs', 'json', 'node', 'wasm']
You can customize this behavior by setting the environment variable KNOWN_EXTS this way:
`
KNOWN_EXTS=js,ts,tsc node --import=specifier-resolution-node/register index.js
If you want to check why an import is not working you can set SPECIFIER_RESOLUTION_NODE_DEBUG=true` environement variable
