Creating an ephermal service mesh using 100% serverless PAAS solutions on GCP.
- GCP Cloud Run
- GCP Cloud Functions
- GCP Cloud PubSub
- Firebase Realtime Database
Make sure to install the emulators for testing.
npm i -g firebase-tools
Firebase can be a little picky about credentials, even when you are working locally. To this end, you will want to modify a few files and generate a service account key
Form the Firebase console, generate a service account key. This will be a JSON file. Mine looks like: serverless-mesh-brianm-firebase-adminsdk-ezhk3-8eed18e18a.json. Add that file to a top level folder called __SECRETS__ or whatever else you feel like using.
Modify the files so that the projet name is correct and the path to your secrets file is correct:
.env.test
.firebaserc
Just like all NodeJS projects, install everything
npm install
In order to test the functions, build them with:
npm run build:functions
Or if you want to modify the code, you can start the watcher
npm run build:functions:watch
The NX tooling treats apps as deployable units. libs are shared libaries. In this case, the apps will represent a node. In the case of the apps/functions this will represent multiple nodes as Firebase Functions can deploy from a single entry point.
Most of the logic for this demo will reside in libs
This project was generated using Nx.
🔎 Nx is a set of Extensible Dev Tools for Monorepos.
Nx supports many plugins which add capabilities for developing different types of applications and different tools.
These capabilities include generating applications, libraries, etc as well as the devtools to test, and build projects as well.
Below are our core plugins:
- React
npm install --save-dev @nrwl/react
- Web (no framework frontends)
npm install --save-dev @nrwl/web
- Angular
npm install --save-dev @nrwl/angular
- Nest
npm install --save-dev @nrwl/nest
- Express
npm install --save-dev @nrwl/express
- Node
npm install --save-dev @nrwl/node
There are also many community plugins you could add.
Run nx g @nrwl/react:app my-app to generate an application.
You can use any of the plugins above to generate applications as well.
When using Nx, you can create multiple applications and libraries in the same workspace.
Run nx g @nrwl/react:lib my-lib to generate a library.
You can also use any of the plugins above to generate libraries as well.
Libraries are sharable across libraries and applications. They can be imported from @anatidaeproject/mylib.
Run nx serve my-app for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.
Run nx g @nrwl/react:component my-component --project=my-app to generate a new component.
Run nx build my-app to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.
Run nx test my-app to execute the unit tests via Jest.
Run nx affected:test to execute the unit tests affected by a change.
Run ng e2e my-app to execute the end-to-end tests via Cypress.
Run nx affected:e2e to execute the end-to-end tests affected by a change.
Run nx dep-graph to see a diagram of the dependencies of your projects.
