nx-aws

nx-aws is a set of plugins for NRWL NX (a set of Extensible Dev Tools for Monorepos).

@nx-aws-plugin/nx-aws-cache

A tool for using AWS S3 as a distributed computational cache for Nx.

Setup

Install the package by running:

yarn add @nx-aws-plugin/nx-aws-cache
npm i @nx-aws-plugin/nx-aws-cache

Then run the init schematic by running:

yarn nx generate @nx-aws-plugin/nx-aws-cache:init
npm run nx generate @nx-aws-plugin/nx-aws-cache:init

This will make the necessary changes to nx.json in your workspace to use nx-aws-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
Access Key Id	Access Key Id.	NXCACHE_AWS_ACCESS_KEY_ID	awsAccessKeyId	my-id
Secret Access Key	Secret Access Key.	NXCACHE_AWS_SECRET_ACCESS_KEY	awsSecretAccessKey	my-key
Profile	Configuration profile to use (applied only if Access Key Id and Secret Access Key are not set).	NXCACHE_AWS_PROFILE	awsProfile	profile-1
Endpoint	Fully qualified endpoint of the web service if a custom endpoint is needed (e.g. when using MinIO).	NXCACHE_AWS_ENDPOINT	awsEndpoint	http://custom.de-eu.myhost.com
Region	Region to which this client will send requests.	NXCACHE_AWS_REGION	awsRegion	eu-central-1
Bucket	Bucket name where cache files are stored or retrieved (can contain sub-paths as well).	NXCACHE_AWS_BUCKET	awsBucket	bucket-name/sub-path
Force Path Style	Whether to force path style URLs for S3 objects (e.g. when using MinIO).	NXCACHE_AWS_FORCE_PATH_STYLE	awsForcePathStyle	true

Important: Environment variables take precedence over nx.json options (introduced in v3.0.0)!

nx.json example

{
  "tasksRunnerOptions": {
  "default": {
    "runner": "@nx-aws-plugin/nx-aws-cache",
    "options": {
      ...
      "awsAccessKeyId": "key",
      "awsSecretAccessKey": "secret",
      "awsEndpoint": "http://custom.de-eu.myhost.com",
      "awsBucket": "bucket-name/sub-path",
      "awsRegion": "eu-central-1",
      "awsForcePathStyle": true,
    }
  }
}

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

Disabling S3 cache

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

NXCACHE_AWS_DISABLE=true

Authentication

Default

AWS authentication can be set-up using default environment variables or using shared credentials, based on AWS documentation.

SSO login

To authenticate with SSO via CLI run

aws sso login

AWS SDK v3 is used under the hood with a support for SSO login.

Build

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

Running unit tests

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

Run yarn nx affected:test to execute the unit tests affected by a change.

Running end-to-end tests

Run yarn nx e2e nx-aws-cache-e2e to execute the end-to-end tests via Jest.

Run yarn nx affected:e2e to execute the end-to-end tests affected by a change.
