historyApiFallback#

• Type: boolean | ConnectHistoryApiFallbackOptions
• Default: false

When Rsbuild's default page routing behavior cannot meet your needs, for example, if you want to be able to access main.html when accessing /, you can set it up using server.historyApiFallback.

Example#

Set historyApiFallback.index to main.html, then main.html can be accessed when accessing / or other routes that would otherwise 404.

export default {
  source: {
    entry: {
      main: './src/index.ts',
    },
  },
  server: {
    htmlFallback: false,
    historyApiFallback: {
      index: '/main.html',
    },
  },
};

When your application contains multiple entries, you may want different visits to fallback to different pages. At this point, you can set more complex rules via the rewrites option:

export default {
  server: {
    historyApiFallback: {
      rewrites: [
        { from: /^\/$/, to: '/views/landing.html' },
        { from: /^\/subpage/, to: '/views/subpage.html' },
        { from: /./, to: '/views/404.html' },
      ],
    },
  },
};
