Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

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 | | Enrypt File Key | Encrypt file in client before send to S3 server. 32 bytes in base64 | NXCACHE_AWS_ENCRYPTION_KEY or NX_CLOUD_ENCRYPTION_KEY | encryptionFileKey | PcZrGOSda3zwWh9yYTJB5bnHORgXf3dphj55tPI74O0= |

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,
      "encryptionFileKey": "Pbfk58EpcK7IxTxWwSXNsTAKmzhJQE+99vkpGftyJg8="
    }
  }
}

Environment variables can be set using .env file - check dotenv documentation. Files are read in the following order:

  • .local.env
  • .env.local
  • .env

Encryption

If you want you can encrypt file before send to s3 server (Client side). Use ENV NX_CLOUD_ENCRYPTION_KEY or NXCACHE_CLOUD_ENCRYPTION_KEY

# Generate new key for encryption.
openssl rand -base64 32

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/integration 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.
