@side/jest-runtime

Custom runtime for Jest which addresses memory leak when using Typescript

NOTE This package was intentionally left as JS instead of being converted to TS because it is only a slight modification of existing Jest code

1. Install SWC if you haven't already @swc/core @swc/jest

2. Make sure to configure SWC if you haven't already:

   {
      "jsc": {
         "parser": {
            "syntax": "typescript",
            "decorators": true
         },
         "transform": {
            "legacyDecorator": true,
            "decoratorMetadata": true
         }
      }
   }
   

3. Install custom runtime: yarn add @side/jest-runtime

4. Use within jest.config.js:

   module.exports = {
     transform: {
       '^.+\\.ts$': '@swc/jest',
     },
     runtime: '@side/jest-runtime',
   };
   

This is the template repository for creating additional typescript libraries. Once a new repository has been created off this template, follow the steps below to finalize the initial setup process:

1. Find all relevant TODO: references and make adjustments accordingly
2. Start making PRs with basic functionality - continue to next section once library is publishable

Enable Publishing

1. Add your new repository to the repositories with access to NPM_PUBLISH_TOKEN org level secret
2. Create a PR removing if: ${{ false }} from release workflow
3. Merge above mentioned PR to create first release - this will take a while since all PRs up until this first release will be marked as released by semantic-release
