How to call circleCI environment variable in an Angular 2+ project?

问题

I have an angular project that has an api-keys.ts file that looks like this:

export var masterFirebaseConfig = {apiKey: $fireBaseApiKey, authDomain: 'dataJitsu.firebaseapp.com',databaseURL: 'https://datajitsu.firebaseio.com',storageBucket: '',messagingSenderId: '495992924984'};

I think the $fireBaseApiKey is stored as an environment variable in my project on circleCI, as you can see in the picture here:

However, I still get the following error when I run my configuration on circleCI:

ERROR in src/app/api-keys.ts(1,44): error TS2304: Cannot find name '$fireBaseApiKey'. src/app/app.module.ts(75,11): error TS2304: Cannot find name 'apiKey'.

(The error in app.module.ts comes directly from the error in api-keys.ts)

I tried to figure out whether the problem was on the circleCI side or with how I was plugging it into Angular, so I tried to echo out the environmental variable in my configuration file:

version: 2.1
orbs:
  cypress: cypress-io/cypress@1.0.1
steps:
  - run:
      name: Setup Environment Variables
      command: |
        echo '$fireBaseApiKey'
workflows:
  build:
    jobs:
      - cypress/install:
          build: 'npm run build'
          context: fireBaseApiKey
      - cypress/run:
          requires:
            - cypress/install
          start: 'npm start'
          context: fireBaseApiKey

I ssh'ed into the session after it errored out, and I couldn't see any indication that my echo command was even acknowledged.

I am hopeful that help on the echo front or on the Angular front will be productive to address the question/problem.

Furthermore, I am using cypress for integration testing and thus am using Cypress's orb for setting up and running the tests. I wasn't sure how to/whether environment variables to infiltrate orb jobs, so I also added the variable to a context for the project (with both the context and the key of the lone key-value pair having the same name):

Update: here is the output from the circleCI log file:

回答1:

Have you tried echo $fireBaseApiKey (without quotes)?

To troubleshoot CircleCI, it's useful to launch an image locally.

Example: the command below will launch a local ubuntu instance with an environment variable fireBaseApiKey set to asdf-asdf-asdf. Your local files will be mounted in /usr/src/app.

docker run -it -e fireBaseApiKey=asdf-asdf-asdf -v $PWD:/usr/src/app ubuntu bash

To check your environment variable, try:

echo $fireBaseApiKey

cd /usr/src/app and run your build script, step by step. I find it useful to troubleshoot builds failing for unknown reasons.

Ok, I finally figured it out, although probably in a hacky way. I just used sed to substitute my environment variable into my api-keys.ts file.

So, here's the new config.yml script (note the extensive changes, including wait-on: 'http-get://localhost:4200' (note the http-get there instead of http!).

version: 2.1
orbs:
  cypress: cypress-io/cypress@1.5.1
jobs:
  build:
    working_directory: ~/project
    docker:
      - image: circleci/node:9.6.1-browsers
    environment:
      circleCiApiKey: fireBaseApiKey
    steps:
      - checkout
      - run:
          name: Show current branch
          command: |
            echo ${CIRCLE_BRANCH}
            ls -larth
            echo $fireBaseApiKey
            cat src/app/api-keys.ts
            sed -i "s/circleCiApiKey/$fireBaseApiKey/g" src/app/api-keys.ts
            cat src/app/api-keys.ts
      - restore_cache:
          keys:
            - v1-dependencies-{{checksum "package.json"}}
            - v1-dependencies-
      - run:
          name: Install local dependencies
          command: |
            npm install
      - save_cache:
          key: v1-dependencies-{{checksum "package.json"}}
          paths:
            - node_modules
      - run:
          name: Building
          command: npm run build
      - save_cache:
          key: v1-dist-{{ .Environment.CIRCLE_BRANCH}}-{{ .Environment.CIRCLE_SHA1}}
          paths:
            - dist
workflows:
  version: 2.1
  build:
    jobs:
      - build
      - cypress/install:
          requires:
            - build
          build: 'npm run build'
      - cypress/run:
          requires:
            - cypress/install
            - build
          start: 'npm start'
          store_artifacts: true
          wait-on: 'http-get://localhost:4200'

The substitution occurs on the sed -i "s/circleCiApiKey/$fireBaseApiKey/g" src/app/api-keys.ts line.

The api-keys.ts file, in turn contains:

export var masterFirebaseConfig = {
    apiKey: "circleCiApiKey",
    authDomain: "dataJitsu.firebaseapp.com",
    databaseURL: "https://datajitsu.firebaseio.com",
    storageBucket: "",
    messagingSenderId: "495992924984"
  };

export var masterStripeConfig = {
  publicApiTestKey: "pk_test_NKyjLSwnMosdX0mIgQaRRHbS",
  secretApiTestKey: "sk_test_6YWZDNhzfMq3UWZwdvcaOwSa",
  publicApiKey: "",
  secretApiKey: ""
};
