@lwc/jest-resolver

lwc-jest-resolver

The default Jest resolver for finding lwc-* modules. This project leverages lwc-npm-resolver to allow LWC components to import modules by their shorthand. For example, lwc-engine can be imported simply as engine.

For more info on resolvers see the Jest doc.

Requirements

• Node 8.x
• NPM 5.x
• Yarn >= 1.0.0
• Jest >= 21.x

Usage

This resolver will be included as part of LWCs preset Jest configuration. Follow directions on the official doc to use the presets. For example:

{
  "jest": {
    "preset": "lwc-jest-preset"
  }
}

Alternatively, you can directly set the resolver in your config. For example:

{
  "jest": {
    "resolver": "lwc-jest-resolver"
  }
}

If you are writing your own custom resolver, you can point Jest to your resolver and then delegate to this resolver directly, which in turn delegates to the Jest default resolver.
