  useLocalModules: true,
  appPort: 3000,
}));

🎛️ API

oneAppDevCdn( [options] )

Loads the local module map and remote module map for local development.

options

Type: object

provide the options below to load module map, with localDevPublicPath and appPort being required parameters.

localDevPublicPath

Type: string

location on the local filesystem where module-map.json and modules (created by One App's serve-module) are. REQUIRED

appPort

Type: number

Port on which One App is running. Used in order to set up CORS headers. (i.e. 3000) REQUIRED

remoteModuleMapUrl

Type: string

location where the remote module map is located (i.e. https://my-domain.com/map/module-map.json), if this is not provided the local module map will be loaded.

useLocalModules

Type: boolean

Default: false Whether to use modules from localDevPublicPath. Passed as true or false, defaults to false.

Note: Either remoteModuleMapUrl OR useLocalModules is required. If both are provided then the remote module map will be merged with modules from localDevPublicPath with the local modules taking precedence.

useHost

Type: boolean

Default: false Whether to use req.headers.host or localhost. Passed as true or false, defaults to false (localhost).

Note: The req.headers.host is useful if your tests use the one-app-dev-cdn on a CI environment or containers that that require it to be accessible in the network by other containers or servers.

Proxy Support

one-app-dev-cdn respects the HTTP_PROXY, HTTPS_PROXY, and NO_PROXY environment variables.

Make use of these environment variables if the remote module map or modules you want to use are inaccessible without the use of a proxy server.
