By default, LoopBack REST API server provides endpoints exposing an OpenAPI spec document describing application’s API. You can configure this behavior using rest.openApiSpec field in the configuration object passed to RestApplication constructor.

  • servers: Configure servers for OpenAPI spec

  • setServersFromRequest: Set servers based on HTTP request headers, default to false

  • disabled: Set to true to disable endpoints for the OpenAPI spec. It will disable API Explorer too.

  • endpointMapping: Maps urls for various forms of the spec. Default to:

    {
      '/openapi.json': {version: '3.0.0', format: 'json'},
      '/openapi.yaml': {version: '3.0.0', format: 'yaml'},
    }
    

Example application configuration object showing possible customizations:

/src/index.ts

const config: ApplicationConfig = {
    rest: {
    openApiSpec: {
      servers: [{url: 'http://127.0.0.1:8080'}],
      setServersFromRequest: false,
      endpointMapping: {
        '/openapi.json': {version: '3.0.0', format: 'json'},
        '/openapi.yaml': {version: '3.0.0', format: 'yaml'},
      },
    },
  };
});
