Jest transform for loading graphql files
npm install @nitrogql/jest-transform@nitrogql/jest-transformThis package serves as a custom Jest transformer for nitrogql. It is responsible for transforming .graphql files into JavaScript modules that export the parsed GraphQL document.
Example Jest configuration:
``js`
{
"transform": {
"^.+\\.graphql$": ["@nitrogql/jest-transform", {
"configFile": path.resolve(__dirname, "nitrogql.config.js")
}]
}
}
@nitrogql/jest-transform is only capable of emitting ES modules. If you are running CommonJS modules during your tests, you will need to use another transformer (for example, babel-jest or ts-jest) to further transform the output from ES modules to CommonJS.
@nitrogql/jest-transform lets you apply another transformer to the output. To do so, use the additionalTransformer and additionalTransformerFilenameSuffix option:
`js``
{
"transform": {
// For example, if you are using ts-jest...
"^.+\.tsx?": ["ts-jest", { isolatedModules: true }],
"^.+\\.graphql$": ["@nitrogql/jest-transform", {
"configFile": path.resolve(__dirname, "nitrogql.config.yml"),
// Then, use the additionalTransformer option to apply ts-jest to the output.
"additionalTransformer": ["ts-jest", { isolatedModules: true }],
// ts-jest expects .ts files, so we need to change the file extension
// by applying the additionalTransformerFilenameSuffix option.
"additionalTransformerFilenameSuffix": ".ts"
}]
},
}
