sadasant / autorest.typescript

Extension for AutoRest (https://github.com/Azure/autorest) that generates TypeScript code. The transpiled javascript code is isomorphic. It can be run in browser and in node.js environment.

TypeScript Plugin for Autorest

Autorest is a suite of tools to automatically generate SDKs for cloud services. This project provides an autorest extension that generates SDKs in TypeScript.

Note: This project, @autorest/typescript is the latest version of the TS/JS SDK generator and is currently in preview. The earlier stable version of the SDK generator @microsoft.azure/autorest.typescript is available in the v4x branch of the Azure/autorest.typescript repository.

Auto-generate your package in TypeScript using Autorest

It is easy to generate an SDK once you have a swagger specification file.

• You will need first to install Autorest

npm install -g autorest

• You can then generate the SDK as follows:

autorest --typescript <path to the swagger file>

• You will likely need to specify extra flags to control the behavior of the generation, and these flags are listed in the next section.

Options

In addition to the list of Autorest flags, you can further control the behavior of the typescript generator with the following flags:

Flag	Description
--use-core-v2	Uses azure core v2 and it is enabled by default. Please set it to false if you need to regenerate a package that uses core-http and you do not want to do the migration to core v2 in that regeneration. For differences between v1 and v2, please refer to https://github.com/Azure/azure-sdk-for-js/blob/master/sdk/core/README.md
--hide-client	Hides the client class from docs. This is typically useful when the you will write a convenience layer on top of the generated client
--ignore-nullable-on-optional	If an optional property is also marked as nullable, it will be treated as just optional
--generate-metadata	Generates meta files such as readme, license, package.json, etc. Typically, you need to specify this flag in your first generation only
--tracing-info	Controls specification of meta info attached to requests for tracing purposes
--disable-async-iterators	Does not generate async iterators needed for paging operations
--allow-insecure-connection	Allow generated clients to make requests to HTTP endpoints

Language Specific Requirements: TypeScript

For TypeScript projects, simply import autorest-extension-base which implements the AutoRest extension protocol and offers a simple API to register plugins. See index.ts.
