NSDateFormatter

nsdateformatter.com

This is a Swift web application that offers live date formatting using DateFormatter on the server.

This is useful for Swift and Objective-C developers as a way to test out behavior without having to compile & run over and over again.

It was originally written as a means to learn Swift on Linux. It stayed because so many people found it useful!

The Tech Stack

Backend

• Swift 5.9
• Vapor 4

Frontend

• Svelte
• Vite
• Tailwindcss

Deployment

(Previously: Digital Ocean, Heroku)

Current: Netlify front-end, AWS Lambda for backend.

Front-end

The front-end is written in Svelte and uses Vite as a development server.

To run the dev server:

npm run dev

To build the dist folder that contains all the final files for deployment:

npm run build

This is automatically run by Netlify upon deployment.

Running the App Locally

You can use Xcode or launch it via command line.

To build & run the vapor backend server:

swift run

Keep in mind that you have to stop & restart for any Swift-level change.

You'll also need to run the front-end server:

cd front-end && npm run dev

Connect to this front-end server in your browser.

Deployment

This app can run essentially anywhere (and has). The Dockerfile can be used to deploy this on a number of cloud infrastructure or PAAS providers.

Currently this is done with AWS Lambda and Netlify.

To deploy the backend server, run:

just deploy

This will build the docker image and deploy it with a SAM template.

The Netlify deployment happens on a git push.

Pull requests are welcome. Keep in mind that not all suggestions will make it in, as I want this to be an easy to use resource, not an exhaustive list of everything DateFormatter can do.
