eMASS API @mitre/emass_client@3.22.0 Specification

The @mitre/emass_client@3.22.0 is a TypeScript/JavaScript client that utilizes axios to implement the Enterprise Mission Assurance Support Service (eMASS) Representational State Transfer (REST) Application Programming Interface (API) specifications

The generated Node module can be used in the following environments: Environment

• Node.js
• Webpack
• Browserify

Language level

• ES5 - you must have a Promises/A+ library installed
• ES6

Module system

• CommonJS
• ES6 module system

It can be used in both TypeScript and JavaScript. In TypeScript, the definition will be automatically resolved via package.json. (Reference)

Building

To build and compile the typescript sources to javascript use:

npm install
npm run build

Publishing

First build the package then run npm publish

Consuming

navigate to the folder of your consuming project and run one of the following commands.

published:

npm install @mitre/emass_client@3.22.0 --save

unPublished (not recommended):

npm install PATH_TO_GENERATED_PACKAGE --save

Getting Started

Before accessing any of the endpoints provided by the @mitre/emass_client, we need to configure common axios settings.

Axios Configuration

All calls utilizing the @mitre/emass_client@3.22.0 need to initialize axios as follows:

// Load the necessary modules
import * as fs from 'fs';
import * as https from 'https';
import { Configuration } from "@mitre/emass_client/dist/configuration"
import globalAxios, { AxiosPromise, AxiosInstance, AxiosRequestConfig } from '@mitre/emass_client/node_modules/axios';

// Initialize the configuration interface. The apikey is initialized via axios default headers.
const configuration = new Configuration({
  basePath: 'https://emass-url-instances.com',
});

// Initialize the axios request configuration
const axiosRequestConfig: AxiosRequestConfig = {
  httpsAgent: new https.Agent({
    keepAlive: true,
    rejectUnauthorized: false,
    key: fs.readFileSync("path/to/the/key.pem"),
    cert: fs.readFileSync("path/to/the/client.pem"),
    passphrase: "certificate passphrase",
    port: 443,
  })
}

// Create an axios instances
const axiosInstances: AxiosInstance =  globalAxios.create(axiosRequestConfig);
// Configure the necessary keys (api-key and user-uid)
axiosInstances.defaults.headers.common = {
  "api-key": "the-proper-api-key-value",
  "user-uid": 'the.use.id.information'
};

Documentation for API Endpoints Examples

Test Connection endpoint

// Load the TestApi module
import { TestApi } from '@mitre/emass_client/dist/api';

// Create and initialize a TestApi instances (references code snippet above for proper parameters configurations)
const testApi = new TestApi(configuration, configuration.basePath, axiosInstances);

// Invoke the endpoint 
testApi.testConnection().then((data:any) => {
  console.log("API called successfully. Returned data: " + JSON.stringify(data.data, null,2));
}).catch((error:any) => console.error(error));

Artifacts Export endpoint

This example uses the colorize module to color format the output to the command line.

// Load the TestApi module
import { ArtifactsExportApi } from '@mitre/emass_client/dist/api';
import colorize from 'json-colorizer';

// Create and initialize a ArtifactsExportApi instances (references Axios Configuration for proper parameters configurations)
const exportArtifacts = new ArtifactsExportApi(configuration, configuration.basePath, axiosInstances);

// Invoke the endpoint 
exportArtifacts.getSystemArtifactsExport(34, "artifact.txt").then((response:any) => {
  console.log(colorize(JSON.stringify(response.data, null,2)));
}).catch((error:any) => console.error(colorize(JSON.stringify(error.response.data,null,2))));
