Building a local module and you want to load it? This supports loading of your remote and local modules together for local development.
- Loads and serves local module map.
- Loads, serves, and merges remote module map with local module map.
- Acts as a proxy to modules defined in the remote module map.
npm i @americanexpress/one-app-dev-cdn -DLook at the different options you can use under the API section.
import oneAppDevCdn from '@americanexpress/one-app-dev-cdn';
const app = express();
app.use('/static', oneAppDevCdn({
localDevPublicPath: path.join(__dirname, '../../static'),
remoteModuleMapUrl: 'https://my-domain.com/map/module-map.json',
useLocalModules: true,
appPort: 3000,
}));Loads the local module map and remote module map for local development.
Type: object
provide the options below to load module map, with localDevPublicPath and appPort being required parameters.
Type: string
location on the local filesystem where module-map.json and modules (created by One App's serve-module) are. REQUIRED
Type: number
Port on which One App is running. Used in order to set up CORS headers. (i.e. 3000) REQUIRED
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.
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.
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.
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.
