packages/srp/jest.resolver.js

   1 /**
   2  * (NB: this resolver is slightly different from the one under each 'applications/' tests, as here we
   3  * also need to manually resolve 'browser' exports, probably due to different Jest presets).
   4  *
   5  * Jest seems to never resolve the 'import' or 'browser' conditions from the package.json `exports`,
   6  * and instead it only looks for e.g. ['require', 'default', 'node', 'node-addons']
   7  * Since we rely on babel to transform ESM file, we can force the resolver to also consider
   8  * the 'import' and 'browser' fields, if the default resolution method fails.
   9  * However, this means that the CJS conditions always have priority in the module resolution,
  10  * which might cause unexpected issues in some packages (but not in the ones we currently use).
