Snapshot#

Used to decide how the file system snapshots are created and invalidated.

• Type:

type Snapshot = {
  module?: {
    hash?: boolean;
    timestamp?: boolean;
  };
  resolve?: {
    hash?: boolean;
    timestamp?: boolean;
  };
};

snapshot.resolve#

• Type: object = {hash?: boolean, timestamp?: boolean}

• Default: { hash: false, timestamp: true }

Snapshots for resolving of requests. When both hash and timestamp are false, the snapshot will be valid forever.

• hash: Compare content hashes to determine invalidation (more expensive than timestamp, but changes less often).
• timestamp: Compare timestamps to determine invalidation.

snapshot.module#

• Type: object = {hash?: boolean, timestamp?: boolean}

• Default: { hash: false, timestamp: true }

Snapshots for building modules. When both hash and timestamp are false, the snapshot will be valid forever.

• hash: Compare content hashes to determine invalidation (more expensive than timestamp, but changes less often).
• timestamp: Compare timestamps to determine invalidation.

Usage#

You can set the snapshot directly in rspack.config.js:

module.exports = {
  snapshot: {
    resolve: {
      hash: true,
    },
  },
};
