Building Enterprise JavaScript Applications

Updating the npm build script

Everything looks good, but if we run the tests, they will return with the following error:

Error: Cannot find module '../../schema/users/profile.json'

This is because Babel, by default, only processes .js files. Therefore, our .json schema files were not processed or copied over to the dist/ directory, which leads to the preceding error. To fix this, we can update our build npm script to use Babel's --copy-files flag, which will copy over any non-compilable files to the dist/ directory:

"build": "rimraf dist && babel src -d dist --copy-files",

Now, if we run our tests again, they should all pass.
