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')} | |
