Properties ​

alias ​

alias?: Record<string, string>

Add additional paths to the .wxt/tsconfig.json. Use this instead of overwriting the paths in the root tsconfig.json if you want to add new paths.

The key is the import alias and the value is either a relative path to the root directory or an absolute path.

Example ​

ts
{
   *   "testing": "src/utils/testing.ts"
   * }

analysis ​

analysis?: object

Type declaration ​

enabled ​

enabled?: boolean

Explicitly include bundle analysis when running wxt build. This can be overridden by the command line --analyze option.

Default ​

Changing the filename of the outputFile also effects the names of the artifacts generated when setting keepArtifacts to true:

  • "stats.html" => "stats-*.json"
  • "stats/bundle.html" => "bundle-*.json"
  • ".analysis/index.html" => "index-*.json"
Default ​

entrypointLoader ​

entrypointLoader?: "vite-node" | "jiti"

Deprecated ​

Will be removed in v0.20.0, please migrate to using vite-node, the new default.

Method used to import entrypoint files during the build process to extract their options.

  • "vite-node" (default as of 0.19.0): Uses vite-node to import the entrypoints. Automatically includes vite config based on your wxt.config.ts file

transformManifest ​

Transform the final manifest before it's written to the file system. Edit the manifest parameter directly, do not return a new object. Return values are ignored.

Example ​

ts
defineConfig({
  // Add a CSS-only content script.
  transformManifest(manifest) {

root, configFile, and mode should be set in WXT's config instead of Vite's.

This is a function because any vite plugins added need to be recreated for each individual build step, incase they have internal state causing them to fail when reused.

Parameters ​

Source ​

packages/wxt/src/types.ts:411

zip ​

zip?: object

Type declaration ​

artifactTemplate ​

artifactTemplate?: string

Configure the filename output when zipping files.

compressionLevel ​

Compression level to use when zipping files.

Levels: 0 (no compression) to 9 (maximum compression).

Default ​
ts
9
downloadPackages ​

downloadPackages?: string[]

The Firefox review process requires the extension be buildable from source to make reviewing easier. This field allows you to use private packages without exposing your auth tokens.

Just list the name of all the packages you want to download and include in the sources zip. Usually, these will be private packages behind auth tokens, but they don't have to be.

All packages listed here will be downloaded to in .wxt/local_modules/ and an overrides or resolutions field (depending on your package manager) will be added to the package.json, pointing to the downloaded packages.

DO NOT include versions or version filters. Just the package name. If multiple versions of a package are present in the project, all versions will be downloaded and referenced in the package.json correctly.

Default ​
ts
[]
Example ​
ts
// Correct:
["@scope/package-name", "package-name"]

// Incorrect, don't include versions!!!
["@scope/package-name@1.1.3", "package-name@^2"]
exclude ​

exclude?: string[]

Minimatch patterns of files to exclude when zipping the extension.

Example ​
ts
[
  "**/*.map", // Exclude all sourcemaps
]
excludeSources ​

excludeSources?: string[]

Minimatch patterns of files to exclude when creating a ZIP of all your source code for Firefox. Patterns are relative to your config.zip.sourcesRoot.

Hidden files, node_modules, and tests are ignored by default.

Example ​
ts
[
  "coverage", // Include the coverage directory in the `sourcesRoot`
]
includeSources ​

includeSources?: string[]

Minimatch patterns of files to include when creating a ZIP of all your source code for Firefox. Patterns are relative to your config.zip.sourcesRoot.

This setting overrides excludeSources. So if a file matches both lists, it is included in the ZIP.

Example ​
ts
[
  "coverage", // Ignore the coverage directory in the `sourcesRoot`
]
name ​

name?: string

Override the artifactTemplate's {name} template variable. Defaults to the package.json's name, or if that doesn't exist, the current working directories name.

sourcesRoot ​

sourcesRoot?: string

Root directory to ZIP when generating the sources ZIP.

Default ​
ts
config.root
sourcesTemplate ​

sourcesTemplate?: string

Configure the filename output when zipping files.

Available template variables:
