typescript-interface-extractor

typescript-interface-extractor is a CLI tool for extracting interfaces, enums, type aliases, and function definitions into a single .d.ts file from any TypeScript source file. Classes and constants will be replaced with type any. This is useful for creating a small @types library from a TypeScript API library whose size is large. The extracted .d.ts file is self-contained, meaning there are no references to any other TypeScript files, and it should be ignored during compilation.

Installation

You can install typescript-interface-extractor globally using npm:

npm install -g typescript-interface-extractor

Or you can install it as a development dependency in your project:

npm install --save-dev typescript-interface-extractor

Usage

The typescript-interface-extractor command-line tool can be used as follows:

ts-interface-extract --file=<ts file path> --entry=<entry point (namespace or interface)> [--output=<output directory>]

• --file (-f): Path to the TypeScript file to extract from
• --entry (-e): Name of the namespace or interface to extract
• --output (-o): Optional output directory for the extracted .d.ts file. Defaults to the ./output folder in current directory.

Here's an example of how to use typescript-interface-extractor on dv360 googleapi:

ts-interface-extract --file=./node_modules/googleapis/build/src/apis/displayvideo/v1.d.ts --entry=displayvideo_v1

This will extract the namespace named displayvideo_v1 from the file ./node_modules/googleapis/build/src/apis/displayvideo/v1.d.ts and save it as a self-contained displayvideo_v1.d.ts file in the ./output directory.
