nx-gcp-cache

A tool for using GCP Cloud Storage (GCS) as a distributed computational cache for Nx.

Setup

Install the package by running:

yarn add nx-gcp-cache
npm i nx-gcp-cache

Then run the init schematic by running:

yarn nx generate nx-gcp-cache:init
npm run nx generate nx-gcp-cache:init

This will make the necessary changes to nx.json in your workspace to use nx-gcp-cache runner.

Plugin settings

There are two ways to set-up plugin options, using nx.json or Environment variables. Here is a list of all possible options:

Parameter	Description	Environment variable / .env	nx.json	Example
Bucket	Bucket name where cache files are stored or retrieved (can contain sub-paths as well).	NXCACHE_GCP_BUCKET	gcpBucket	bucket-name/sub-path

Important: Environment variables take precedence over nx.json options!

nx.json example

{
  "tasksRunnerOptions": {
  "default": {
    "runner": "nx-gcp-cache",
    "options": {
      ...
      "gcpBucket": "bucket-name/sub-path"
    }
  }
}

Environment variables can be set using .env file - check dotenv documentation.

Disabling GCS cache

Remote cache can be disabled in favor of local cache using an environment variable

NXCACHE_GCP_DISABLE=true

Authentication

Important: Only ADC authentication is supported right now

Default

GCP authentication can be set-up using Application Default Credentials (ADC), based on GCP ADC documentation.

SSO login

To authenticate with SSO via Google Cloud CLI run gcloud auth application-default login

Build

Run yarn build nx-gcp-cache to build the plugin. The build artifacts will be stored in the lib/ directory. Use the --prod flag for a production build.

Running unit tests

Run yarn test nx-gcp-cache to execute the unit tests via Jest.
