eMASS Client

The eMASS client repository (emass_client) maintains the Enterprise Mission Assurance Support Service (eMASS) Representational State Transfer (REST) Application Programming Interface (API) specifications and executables. The executables packages currently provided are: RubyGem, TypeScript Node, and Python.

NOTE: A CLI tool called emasser, has been developed that makes use of the emass_client RubyGem. Additionally, the SAF CLI implements the emass_client npm package.

Highlights

eMASS API Specification

The eMASS API is documented in YAML and can be viewed utilizing a multitude of visualization tools. Included is a dependency-free (and nice looking) rendering tool for viewing the API specification. The documentation is automatically generated using a Continuos Integration (CI) action redoc-cli command line tool.

eMASS API Viewer

This repository allows anyone to visualize and interact with the API’s resources without having any of the implementation logic in place, via hosted or local mock servers. Please reference Developers Instruction on how to setup a local mock server

eMASS API Clients Generation Process

The executable packages (APIs) generated are used to access eMASS data and functionality by external third-party developers, business partners, or internal departments.

The following emass_client executable packages are generated by this repository:

• Ruby - The ruby package is hosted and available in the RubyGems.

• Typescript - The typescript package is hosted and available in the NpmRegistry.

• Python - The python package is hosted and available in the PyPIRegistry.

Making Changes to eMASS Clients

Changes to the eMASS clients are made by modifying the eMASS API specification file eMASSRestOpenApi.yaml. Modification to this file triggers the clients’ generation actions where all client packages are generated, and published to the appropriate repositories when the PR branch is merged into the main branch.

After either forking or creating a branch for the main repository update the code via a pull request (PR) or directly on the branch.

The proper process for making client code updates are as follows:

• Step 1 Update the eMASS API specification file eMASSRestOpenApi.yaml

• Step 2 Make the necessary changes (update the version field) to the clients generation configuration files:
  • Ruby (src/openapi/templates/ruby/ruby-generator-config.json)
  • Typescript(src/openapi/templates/typescript/typescript-generator-config.json)
  • Python (src/openapi/templates/python/python-generator-config.json)

• Step 3 Push the content to the repository

• Step 4 Once all test pass merge the pull request

Repository Architecture

The process provided by this repository is depicted by the architecture diagram below. In a nutshell, it hosts the eMAASS API specification, documentation, interactive visualization tools, and generates clients for the following languages: ruby, typescript, and python.

Client Application

The emass_client executable packages can be included in other projects, or used to generate CLI tools that require access to an eMASS instance as demonstrated by the diagram below.
