Share Your Cache

The computation cache provided by Nx can be distributed across multiple machines. You can either build an implementation of the cache or use Nx Cloud. Nx Cloud is an app that provides a fast and zero-config implementation of distributed caching. It's completely free for OSS projects and for most closed-sourced projects (read more here).

Diagram showing Teika sharing his cache with CI, Kimiko and James

In this diagram, Teika runs the build once on his machine, then CI, Kimiko and James can use the cached artifact from Teika instead of re-executing the same work.

You can connect your workspace to Nx Cloud by running:

npx nx connect-to-nx-cloud

Terminal

~/workspace❯

npx nx connect-to-nx-cloud

✔ Enable distributed caching to make your CI faster · Yes

>  NX  Generating @nrwl/nx-cloud:init

UPDATE nx.json

 >  NX   Distributed caching via Nx Cloud has been enabled

   In addition to the caching, Nx Cloud provides config-free distributed execution,
   UI for viewing complex runs and GitHub integration. Learn more at https://nx.app

   Your workspace is currently unclaimed. Run details from unclaimed workspaces can be viewed on cloud.nx.app by anyone
   with the link. Claim your workspace at the following link to restrict access.

To see the remote cache in action, run:

nx build header && nx reset && nx build header

Terminal

~/workspace❯

nx build header && nx reset && nx build header

> nx run header:build

> header@0.0.0 build
> rimraf dist && rollup --config

src/index.tsx → dist...
created dist in 786ms

 >  NX   Successfully ran target build for project header (2s)

   See logs and investigate cache misses at https://cloud.nx.app/runs/k0HDHACpL8


 >  NX   Resetting the Nx workspace cache and stopping the Nx Daemon.

   This might take a few minutes.


 >  NX   Daemon Server - Stopped


 >  NX   Successfully reset the Nx workspace.


> nx run header:build  [remote cache]


> header@0.0.0 build
> rimraf dist && rollup --config


src/index.tsx → dist...
created dist in 786ms

 —————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————

 >  NX   Successfully ran target build for project header (664ms)

   Nx read the output from the cache instead of running the command for 1 out of 1 tasks.

   Nx Cloud made it possible to reuse header: https://nx.app/runs/P0X6ZGTkqZ

Connecting Your Workspace to Your Nx Cloud Account

After you have enabled Nx Cloud in your workspace, you will see the following:

>  NX   NOTE  Nx Cloud has been enabled

  Your workspace is currently public. Anybody with code access
  can view the workspace on nx.app.

  You can connect the workspace to your Nx Cloud account at
  https://nx.app/orgs/workspace-setup?accessToken=N2Y3NzcyO...
  (You can do this later.)

Click on this link to associate the workspace with your Nx Cloud account. If you don't have an Nx Cloud account, you can create one on the spot.

After you claim your workspace, you will be able to manage permissions, create access tokens, set up billing, and so forth.

You will also see an interactive tutorial helping you explore distributed caching and the Nx Cloud user interface.

If you lose this link, you can still connect your workspace to Nx Cloud. Go to nx.app, create an account, and connect your workspace using the access token from nx.json.

Skipping Cloud

Similar to how --skip-nx-cache will instruct Nx not to use the cache, passing --no-cloud will tell Nx not to use Nx Cloud.
