以 @ 开头的导入在 Je​​st 中不起作用

Question

I recently joined a team of developers to work on their webapp. I am writing tests for it and most of their files use @ imports instead of writing the filepath in the format of ../../

When trying to write tests in Jest for these I am unable to import and keep getting this error

Cannot find module '@util/helpers.js' from '_controller.js'

Is there a way I can configure jest to accept @ based imports? I have looked long and hard online and so far have not been able to find any solution that works.

Answer 1

Adding this to module name mapper fixed it

"moduleNameMapper": {
      "^@util(.*)$": "<rootDir>/src/util$1",
    }
