4 Steps from JavaScript to TypeScript

This repo shows you the steps to go through to update a project from JavaScript to TypeScript.

It was based on the advice from Dominik Kundel's blog post on moving to TypeScript at your own pace.

Running the application

First clone or download the repo and change into the directory.

git clone https://github.com/philnash/four-steps-from-javascript-to-typescript.git
cd four-steps-from-javascript-to-typescript

Install the dependencies:

npm install

Run the application.

npm start

You can now visit http://localhost:3000 and see a static HTML page or make a POST request to http://localhost:3000/webhooks/messages and get a dad joke in TwiML format for responding to incoming SMS messages to a Twilio number.

curl --data "" http://localhost:3000/webhooks/messages

Moving to TypeScript

You can follow the directions in the blog post to move this repo to TypeScript. There are also branches that show the changes at each stage.
