APIMiner is a powerful tool designed to automatically extract API calls from your frontend JavaScript or TypeScript codebase and generate Postman collections with minimal effort. Ideal for frontend developers, APIMiner helps you document and test the API interactions within your client-side applications, ensuring that your API usage is transparent and well-organized.
If you find APIMiner useful, please consider giving it a star on GitHub! Your support helps the project grow and improves visibility within the community.
In modern web development, frontend applications increasingly rely on APIs to interact with servers and other services. Documenting and testing these API interactions can be a challenging task, especially in large or complex applications. APIMiner is here to make this easier by automatically generating Postman collections from your frontend codebase.
While many tools exist for documenting backend APIs, frontend developers often lack similar tools that focus on the client side. APIMiner fills this gap by providing a seamless way to document and test all API interactions in your frontend code, whether you're building with React, Vue, Angular, or plain JavaScript.
To install APIMiner, use npm:
npm install -g apiminer
This will install APIMiner globally, allowing you to use it from anywhere in your terminal.
APIMiner is designed to be used via the command line. The basic usage pattern involves specifying the directory containing your frontend code.
apiminer ./path/to/your/frontend/project
This command will scan the specified directory for API calls and generate a Postman collection in the current working directory.
APIMiner provides several options to customize the generation process:
-o, --output <path>
: Specifies the output path for the generated Postman collection. If not provided, the collection will be saved in the current directory as postman_collection.json
.-i, --include <pattern>
: Include only files that match the given pattern. Useful for focusing the scan on specific parts of your frontend codebase.-e, --exclude <pattern>
: Exclude files that match the given pattern, helping to skip irrelevant files or directories.To generate a Postman collection for your frontend project:
apiminer ./src
This will scan all files in the src
directory and create a Postman collection.
If you want to save the collection to a specific location:
apiminer ./src -o ./docs/api/postman_collection.json
This will generate the Postman collection and save it in the docs/api
directory.
To include only certain files or exclude others:
apiminer ./src -i '**/*.ts' -e '**/*.spec.ts'
This will include only TypeScript files (.ts
) and exclude test files (.spec.ts
).
APIMiner is designed to work with a variety of popular HTTP libraries commonly used in frontend development:
APIMiner uses AST (Abstract Syntax Tree) traversal to identify API calls made using these libraries. It then extracts relevant information such as HTTP methods, URLs, and request bodies to build the Postman collection.
APIMiner’s context management is crucial for accurately documenting your API interactions. As the tool processes your frontend files, it maintains a global context that tracks:
This context-aware approach ensures that APIMiner can accurately understand and extract API interactions, even in complex frontend applications.
APIMiner deeply analyzes your frontend code using AST traversal. It walks through the syntax tree of each file, identifying and processing API calls. By supporting various node types and handling edge cases like dynamic URLs or complex request bodies, APIMiner ensures comprehensive extraction of all relevant API calls.
APIMiner includes a robust suite of tests to ensure reliability and correctness. The tests cover a wide range of scenarios, including:
To run the tests:
npm test
The tests are written using Jest and validate the core functionality of APIMiner, ensuring that it performs as expected across different frontend codebases.
