Deno URL Shortener

This is a simple URL Shortener built to learn Deno & Fresh framework.

How to run

Prerequisite

• Provision CockroachDB Serverless instance
• Create Github Oauth application
• Create .env file with the following content

DATABASE_URL="postgresql://sdil:xxx@xxx.xxxx:26257/defaultdb?sslmode=verify-full&options=--cluster%3Dxxx"
GITHUB_CLIENT_ID="xxx"
GITHUB_CLIENT_SECRET="xxx"
GITHUB_CALLBACK_URL="http://localhost:8000/api/github_callback"

Run DB migrations

migrate -database $COCKROACH_DB_URL -path db/migrations/ up

Start the project:

deno task start

This will watch the project directory and restart as necessary.

My opinions

What I like about Deno/Fresh

• Super fast: Deno backend can handle thousands of requests per second; Preact is super fast but I don't know how to measure this
• Configuration is super easy, there's no tsconfig files, package.json, prettier, etc.
• Deno tooling looks similar to Go's where it can immediately format and lint the files without 3rd party packages
• The upgrade path is quite smooth as the Fresh team provides a script to update the relevant files

What I don't like about Deno/Fresh

• It's still early so the resources are still scarce
• Ecosystem support is still weak. I really wish UI components/libraries like Chakra UI, Bulma, etc. are supported (hopefully they will soon since they just released a plugin module)

Things I wish Deno/Fresh do

• Prerender the island
• Support Chakra and other UI components

Conclusion

• I would probably use Deno & Fresh in the future to build website with a lot of contents because of its performance. It's however in my opinion, not suitable for interactive web app, which is should be done using NextJS or Remix.
