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 specification, and auto-generates API interfaces that allow application to interact with eMASS applications.

NOTE: A CLI application 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 specification provides a broad understanding of how the API behaves and how the API links with an eMASS application instances. It explains how the API functions and the results to expect when using the API.

eMASS API Getting Started

Provides information on how to register external application that utilize the eMASS API to perform assessments and complete actions associated with system records. .

eMASS API Viewer

Allows interaction with the API’s resources without having any of the implementation logic in place. A local mock servers cn also be used, 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.

How to Generate eMASS Clients

Generation of the API clients are accomplished by updating or 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.

The preferable way to update the specification file is by forking this repository or creating a new branch in this repository followed by a Pull Request (PR), than making the necessary updates and merged PR into the main 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 github actions finish and pass merge the pull request

Generate Clients for Other Programming Languages

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.
