Cache#

Rspack will cache snapshots and intermediate products during the build process and use them in the next build to improve the speed of the build. Rspack will perform caching operations in the following process:

• resolve module

At this stage, Rspack will cache the results of module resolve requests and generate snapshots. When rebuilding, it will directly reuse valid snapshots to obtain results. For more snapshot configurations, refer to snapshot.resolve.

• build module

At this stage, Rspack will cache the results of module build and generate snapshots. When rebuilding, it will directly reuse valid snapshots to obtain results. For more snapshot configurations, refer to snapshot.module.

• module code generation

At this stage, Rspack will cache the final code generated by the module, and if the module has not changed, it will directly reuse the generated code when rebuilding.

This configuration currently only supports setting whether to enable caching.

• Type: boolean
• Default: production mode is false, development mode is true

Usage#

You can disable the cache directly in rspack.config.js:

module.exports = {
  cache: false,
};
