Use Remote Caching (Nx Replay)
By default Nx caches task computations locally. However, to benefit from the cache across your team and in particular on CI, the computation cache can also be distributed across multiple machines.
The Nx Replay feature of Nx Cloud is a fast, secure and zero-config implementation of remote caching.
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.
Setting Up Nx Cloud
To use Nx Replay you need to connect your workspace to Nx Cloud. See the connect to Nx Cloud recipe.
See Remote Caching in Action
To see the remote cache in action, run:
~/workspace❯
nx build header && nx reset && nx build header
1> nx run header:build
2
3> header@0.0.0 build
4> rimraf dist && rollup --config

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

43 Nx Cloud made it possible to reuse header: https://nx.app/runs/P0X6ZGTkqZ
44Skipping Cloud Cache
Similar to how --skip-nx-cache will instruct Nx not to use the local cache, passing --no-cloud will tell Nx not to use the remote cache from Nx Cloud.
