#manifest

• Type: boolean | PluginManifestOptions
• Default value: undefined

Controls whether the plugin generates manifest artifacts and how they are produced. When enabled, the plugin emits mf-manifest.json and mf-stats.json (names can be customized via fileName) on every build so that other tools can consume them directly through processAssets or from the final build output.

• mf-stats.json: captures the full build statistics, including the assets for exposes/shared/remotes, metaData (plugin version, build info, remoteEntry, etc.), and any additional asset analysis. Ideal for debugging or merging stats across environments.
• mf-manifest.json: a runtime-oriented manifest distilled from the stats. It keeps the stable structure that Module Federation consumers read when loading remote modules. The exposes/shared/remotes entries describe what is actually available to consumers.

The PluginManifestOptions types are as follows:

interface PluginManifestOptions {  filePath?: string;  disableAssetsAnalyze?: boolean;  fileName?: string; }

#filePath

• Type: string
• Default value: undefined

manifest filePath

#fileName

• Type: string
• Default value: 'mf-manifest.json'

manifest fileName

If fileName is provided, the companion stats file automatically receives a -stats suffix (for example, fileName: 'mf.json' produces both mf.json and mf-stats.json). Generated files are written under filePath when that option is set.

#disableAssetsAnalyze

• Type: boolean
• Required: No
• Default value: undefined

When analyzing assets in complex projects, it can take a long time. By setting this option to true, asset analysis will be disabled, optimizing build time. If the project is purely consumer-oriented, it will be set to true in dev by default. If set to true, the shared and exposes fields will not be present in the manifest, and assets will not be present in remotes.
