Next Right Now has introduced module path aliases as part of the huge refactoring of the folder structure on January 20, 2021:

How/where are configured module path aliases?

The following path aliases have been configured thorough the whole app (at 7 different places). They’re used in

  • tsconfig.json
  • cypress/tsconfig.json
  • .storybook/jsconfig.json
  • cypress/jsconfig.json
  • .storybook/main.js:webpackFinal
  • jest.config.js:moduleNameMapper

For instance, here’s what contains /tsconfig.json:

    "@/app/*": [
    "@/common/*": [
    "@/components/*": [
    "@/utils/*": [
    "@/layouts/*": [
    "@/modules/*": [
    "@/pages/*": [
