General types and classes

static class PlatformHelper

The main class in which the methods of working with the MEF.DEV platform

class MefDevAuthInterceptor

Ensures security headers are added to requests. It is used as an ordinary interceptor. An example is here

class PlatformSseHelper

A service class that takes over part of the logic for working with SSE. Can be used for cases where only work with SSE is required.

General methods

The library's features are located by the static class PlatformHelper. Its main methods are given in the table below:

Name	Return type	Description
`PluginDataSync`	UiProfileViewModel	Return plugin data synchronous if data will previously downloaded (PlatformHelper.loadPlatformOptions() or PlatformHelper.setOptions(...))
`getPluginData()`	Observable \<UiProfileViewModel>	Return plugin data asynchronous. After successfully loading, data stored(session mode). Initiates loading of plugin data if no previusly loaded.
`setOptions(options: GetInfoSpecificOptions)`	Observable \<UiProfileViewModel>	This method used for setup data for running plugin on local machine(debug mode). Initiates loading of plugin data. Example and best practice on this demo
`loadPlatformOptions()`	Observable\<UiProfileViewModel>	Load and return plugin data asynchronous if plugin in production mode(work under platform). After successfully loading, store plugin data. For development mode use `PlatformHelper.setOptions(...)`
`getAssetUrl ()`	string	Return the asset path. In debug mode(on local machine) is 'assets'. But after uploading plugin in platform this path change
`updatePluginsRoutes(routes: Routes)`	Routes	Update plugin components routes. After upload on platform path is changed. Its method help platform resolve plugin routes. `Required to usage`, code example
`getSseStream()`	Observable\<any>	Emit object from plugin SSE stream.
`sendSseStream(data: any)`	Observable\<any>	Send any object to plugin SSE stream.

Specific methods(Use for creating own secure interceptor or other stuff)

Name	Return type	Description
setAuthHeaders(request: HttpRequest \| any, bearerToken: string \| undefined = undefined)	HttpRequest\<any>	Used for manual adding security headers for request.
refreshPlatformAccessToken()	Observable\<string>	Used for manual initiates refresh platform token. Token expire in few minutes. 455 request status signaled about token expiration.

Depricated methods list:

Name	Return type	Description
`getPluginLocalData()`	PluginLocalData \| undefined	Return plugin data (old interface). Works only in production mode
`_getPlatformIHttpService()`	IHttpService \| undefined	Return platform instance of IHttpService (old interface). Works only in production mode

Scripts

There are two main scripts available: mef-dev-publish and generate-version-file. To run them, use the following command: npm explore @natec/mef-dev-platform-connector -- npm run {script} [argsName=argValue]

generate-version-file

This script creates a version.js file containing a unique identifier for any plugin version. It is required for publishing on the mef.dev platform.

Example: npm explore @natec/mef-dev-platform-connector -- npm run generate-version-file

mef-dev-publish

This script builds, generates the version.js file, and publishes the plugin to the mef.dev platform from the CLI, without any manipulations on the site interface.

Example: `npm explore @natec/mef-dev-platform-connector -- npm run mef-dev-publish debug=true

Argument List

Argument	Description
pluginBuildCommand	npm script what start build plugin process, default: `build:plugin`
apiUrl	platform API web address, default: `https://sandbox.mef.dev`
bauth	Basic credentials for publish, format `NAME:PASS`
alias	Alias of plugin (optional)
updateTenantVersion	Update tenant plugin version after upload, default: `true`
updateConfiguration	Update plugin configuration after upload, default: `false`
debug	Log expanded information, default: `false`

Environment file

You can declare any arguments in environment.ts. Note that CLI arguments take priority.

// /src/environments/environment.ts
import { PLUGIN_VERSION } from './version';

export const environment = {
  production: false,
  version: PLUGIN_VERSION.version,
  alias: 'test',
  bauth: 'NAME:PASS',
  apiUrl: 'https://api.mef.dev'
};

metadata.json file

At the root of the project (near the angular.json file), you need to create a metadata.json file. This file will be automatically applied for publication and stores the data required for publication

// /metadata.json
{
  "name": "basic-request-demo",
  "serviceType": "APIUI",
  "description": "basic-request-demo",
  "dependencies": [],
  "config":{
    "routesUI":[
      {
          "lang":"en",
          "routerLink":"plugin-information",
          "label":"plugin-information"
      }
    ]
  },
  "externalUrl": null,
  "configuration": "{ \"someProp\": \"some value\" }"
}
