Jest transformer with esbuild speed

This is a fork of esbuild-jest with the following added features:

• Strict mode enabled for modules
• Hoisted jest.mock calls with nebu

yarn add esbuild-jest@npm:@alloc/esbuild-jest esbuild -D

esbuild-jest transformer should be used in your Jest config file like this:

{
  "transform": {
    "^.+\\.tsx?$": "esbuild-jest"
  }
}

export interface Options {
  jsxFactory?: string
  jsxFragment?: string
  loaders?: {
    [ext: string]: Loader
  }
  target?: string
}

{
  "transform": {
    "^.+\\.tsx?$": [
      "esbuild-jest",
      {
        loaders: {
          '.spec.ts': 'tsx'
        }
      }
    ]
  }
}
