Workspace Settings

Various project settings can be controlled from the project.json file, located in each project folder.
E2E Testing Configuration
The default Nx setup for E2E tests is experiencing timeouts during some of our tests. This is due to long build and compile time of NextJS apps. In effort to optimize this process we have created an e2e-ci.js script in the scripts/ directory. It starts by creating a production build of the app under testing, before starting the Cypress tests. Following is a documentation of the configuration needed to enable the e2e-ci task.
Pre-requisites
Setting API_MOCKS
NextJS
We need to make sure that the API_MOCKS environment variable is set in the next.config.js
// ...
serverRuntimeConfig: {
  // ...
},
publicRuntimeConfig: {
  // ...
},
env: {
  API_MOCKS: process.env.API_MOCKS,
},
React
For React apps we have a common webpack config in libs/share/webpack which we use to make sure the API_MOCKS environment variable is set, along with other common plugins and settings.
Your webpack.config.js should look like this:
// eslint-disable-next-line @typescript-eslint/no-var-requires
const nrwlConfig = require('./../../libs/shared/webpack/nrwl-config')
​
module.exports = (config, context) => {
  // Add our common webpack config
  nrwlConfig(config)
​
  // Here you can add app specific config
​
  return config
}
devServerTarget and Cypress baseUrl
We need to set the devServerTarget for the production config of the e2e task for the corresponding e2e project.
We also need to let Cypress now what the baseUrl of our app is (as we are running it manually). That is done by adding baseUrl to the options key of the e2e task.
See the following example for the web project:
"e2e": {
  "executor": "@nrwl/cypress:cypress",
  "options": {
    "cypressConfig": "apps/web-e2e/cypress.config.ts",
    "tsConfig": "apps/web-e2e/tsconfig.e2e.json",
    "baseUrl": "http://localhost:4200",
    "devServerTarget": "web:serve"
  },
  "configurations": {
    "production": {
      "devServerTarget": ""
    }
  }
},
Add e2e-ci task
Finally we need to add a e2e-ci task to the architect property of the corrensponding e2e project.
NextJS
"e2e-ci": {
  "executor": "@nrwl/workspace:run-commands",
  "options": {
    "command": "yarn e2e-ci -n web-e2e -d dist/apps/web"
  }
},
React
"e2e-ci": {
  "executor": "@nrwl/workspace:run-commands",
  "options": {
    "command": "yarn e2e-ci -n service-portal-e2e -t react -f dist/apps/service-portal -b /minarsidur"
  }
},
Configure
The e2e-ci.js script requires few parameters:
-n - Required. The name of the e2e project. The script uses this name to find the name of the target app (by stripping of the -e2e ending).
-d - Required. Sets the output directory for the production build.
-s - Boolean to indicate if to use --skip-nx-cache
-t - Only for React. Sets the app type to react.
-b - Optional for React. If the app is deployed to a sub-directory, that is the base in index.html this option is needed to set that path.
Further details can be found be using the -h parameter for the script:
node scripts/e2e-ci.js -h
E2E test locally
To test e2e locally it can either be done like before using the e2etask
yarn e2e web-e2e
or using the e2e-ci task
yarn nx run web-e2e:e2e-ci
E2E in CI
This task is executed as part of our GitHub CI pipeline via the 40_e2e.sh.
