aws-sdk-js-codemod

This repository contains a collection of codemod scripts for use with JSCodeshift that help update AWS SDK for JavaScript APIs.

The aws-sdk-js-codemod CLI is a lightweight wrapper over jscodeshift. It processes --help, --version and --transform options before passing them downstream.

You can provide names of the custom transforms instead of a local path or url:

 v2-to-v3  Converts AWS SDK for JavaScript APIs in a Javascript/TypeScript
           codebase from version 2 (v2) to version 3 (v3).

Please review the code change thoroughly for required functionality before deploying it to production. If the transformation is not complete or is incorrect, please report the issue on GitHub.

Prerequisites

To use aws-sdk-js-codemod, please install Node.js.

Usage

  • Optionally execute dry-run for the transform, and print transformed files on stdout: 
    npx aws-sdk-js-codemod@latest --dry --print -t v2-to-v3 PATH...
  • Run transform, and make changes to files: 
    npx aws-sdk-js-codemod@latest -t v2-to-v3 PATH...

Example

$ cat example.ts
import AWS from "aws-sdk";
const client = new AWS.DynamoDB();
const response = await client.listTables({}).promise();

$ npx aws-sdk-js-codemod@latest -t v2-to-v3 example.ts

$ cat example.ts
import { DynamoDB } from "@aws-sdk/client-dynamodb";
const client = new DynamoDB();
const response = await client.listTables({});
