This is an Encore starter for a URL Shortener. It has two API endpoints and a PostgreSQL database to store the URL IDs and retrieve the full URL given an ID.

Build from scratch with a tutorial

If you prefer to built it yourself, check out the tutorial to learn how to build this application from scratch.

Prerequisites

Install Encore:

• macOS: brew install encoredev/tap/encore
• Linux: curl -L https://encore.dev/install.sh | bash
• Windows: iwr https://encore.dev/install.ps1 | iex

Docker:

1. Install Docker
2. Start Docker

Create app

Create a local app from this template:

encore app create my-app-name --example=ts/url-shortener

Run app locally

Before running your application, make sure you have Docker installed and running. Then run this command from your application's root folder:

encore run

Using the API

url.shorten — Shortens a URL and adds it to the database

curl 'http://127.0.0.1:4000/url' -d '{"url":"https://google.com"}'

url.get — Gets a URL from the database using a short ID

curl 'http://127.0.0.1:4000/url/:id'

url.list — Lists all shortened URLs

curl 'http://127.0.0.1:4000/url'

Open the developer dashboard

While encore run is running, open http://localhost:9400 to access Encore's local developer dashboard.

Here you can see API docs, make requests in the API explorer, and view traces of the responses.

Using the API

To see that your app is running, you can ping the API to shorten a url.

curl 'http://localhost:4000/url' -d '{"url":"https://news.ycombinator.com"}'

When you ping the API, you will see traces and logs appearing in the local development dashboard: http://localhost:9400

Connecting to databases

You can connect to your databases via psql shell:

encore db shell <database-name> --env=local --superuser

Learn more in the CLI docs.

Deployment

Self-hosting

See the self-hosting instructions for how to use encore build docker to create a Docker image and configure it.

Encore Cloud Platform

Deploy your application to a free staging environment in Encore's development cloud using git push encore:

git commit -m 'Commit message'
git push encore

You can also open your app in the Cloud Dashboard to integrate with GitHub, or connect your AWS/GCP account, enabling Encore to automatically handle cloud deployments for you.

Link to GitHub

1. Create a GitHub repo, commit and push the app.
2. Open your app in the Cloud Dashboard.
3. Go to Settings ➔ GitHub and click on Link app to GitHub to link your app to GitHub and select the repo you just created.
4. To configure Encore to automatically trigger deploys when you push to a specific branch name, go to the Overview page for your intended environment. Click on Settings and then in the section Branch Push configure the Branch name and hit Save.
5. Commit and push a change to GitHub to trigger a deploy.
