Use auto generated client code to consume your API from an Angular app

OpenAPI is a specification for creating RESTful APIs, and OpenAPI Generator is a tool that can help you generate client libraries in different programming languages, including TypeScript. In this article, we will walk you through the steps to install and use OpenAPI Generator CLI to generate TypeScript client code for an existing API using the Swagger.json file and include it as part of your Angular app.

The first step is to install OpenAPI Generator CLI on your machine. You can do this by running the following command in your terminal:

This command will install the OpenAPI Generator CLI globally on your machine. You can verify that it has been installed correctly by running the following command:

This should display the version of the OpenAPI Generator CLI that you have installed.

The next step is to obtain the Swagger.json file for the API that you want to generate the client code for. The Swagger.json file is a machine-readable representation of your API that describes its endpoints, parameters, and responses.

If you already have the Swagger.json file, you can skip this step. Otherwise, you can obtain it by using a tool like Swagger UI or by contacting the API provider.

Once you have the Swagger.json file, you can use the OpenAPI Generator CLI to generate TypeScript client code for your API. In this example, we will assume that you want to generate the client code in the src/app/api folder.

To generate the client code, run the following command in your terminal:

Replace /path/to/swagger.json with the path to your Swagger.json file. This command tells the OpenAPI…
