nx-gcp-cache

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

Setup

Install the package by running:

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

Then run the init schematic by running:

`bash
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!

$3

`json
{
"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

`bash
NXCACHE_GCP_DISABLE=true
`

Authentication

> Important: Only ADC authentication is supported right now

$3

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

$3

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.
