Swagger to Angular Services Generator

A command-line interface (CLI) tool that generates Angular services from Swagger or OpenAPI definition files.

Installation

This is a Node.js module available through the npm registry. Install it globally using npm:

npm install -g swagger-to-angular

It can be installed only on project scope using npm:

npm install swagger-to-angular

Usage

swagger-to-angular -i /path/to/swagger_or_openapi_file -o /path/to/angular_project

Where:

/path/to/swagger_or_openapi_file is the path to your Swagger or OpenAPI definition file (.json or .yaml).

/path/to/angular_project is the path to your Angular project directory where the services will be created.

This command generates an Angular service for each operation defined in the Swagger/OpenAPI file, and a base service that all other services extend.

In case unit-test .spec files need to be generated, adding -t or --test parameter will make the library to generate a spec file for each service generated.

Example

Let's say you have an OpenAPI definition file at /home/user/api.yaml, and an Angular project at /home/user/my-angular-project. You can generate services using the following command:

swagger-to-angular -i /home/user/api.yaml -o /home/user/my_angular_project/services_directory

After running this command, you will find a .ts file for each operation defined in api.yaml inside your Angular project directory, along with a base.service.ts file.

In this previous example, if unit-test spec files are required:

swagger-to-angular -i /home/user/api.yaml -o /home/user/my_angular_project/services_directory -t

Note

This script assumes that the Swagger/OpenAPI file is well-formed and may not handle all edge cases. It's a good starting point, but for production usage, you would likely need to extend and harden this script according to your specific needs.
