Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax.
|
||||
|
||||
Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration.
|
||||
|
||||
By default "node_modules" folder is ignored by transformers.
|
||||
|
||||
Here's what you can do:
|
||||
${DOT}If you are trying to use ECMAScript Modules, see ${_chalk().default.underline(
|
||||
'https://jestjs.io/docs/ecmascript-modules'
|
||||
)} for how to enable it.
|
||||
${DOT}If you are trying to use TypeScript, see ${_chalk().default.underline(
|
||||
'https://jestjs.io/docs/getting-started#using-typescript'
|
||||
)}
|
||||
${DOT}To have some of your "node_modules" files transformed, you can specify a custom ${_chalk().default.bold(
|
||||
'"transformIgnorePatterns"'
|
||||
)} in your config.
|
||||
${DOT}If you need a custom transformation specify a ${_chalk().default.bold(
|
||||
'"transform"'
|
||||
)} option in your config.
|
||||
${DOT}If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the ${_chalk().default.bold(
|
||||
'"moduleNameMapper"'
|
||||
)} config option.
|
||||
|
||||
You'll find more details and examples of these config options in the docs:
|
||||
${_chalk().default.cyan('https://jestjs.io/docs/configuration')}
|
||||
For information about custom transformations, see:
|
||||
${_chalk().default.cyan('https://jestjs.io/docs/code-transformation')}
|
||||
|
||||
${_chalk().default.bold.red('Details:')}
|
||||
|
||||
${e.stack ?? ''}`.trimRight();
|
||||
return e;
|
||||
}
