🚀 Feature: Adding Bun runtime

[byawitz]

🔖 Feature description

Adding Bun to open-runtimes.

🎤 Pitch

Bun is a real fast JavaScript runtime.

Bun advantages:

• Built-in server
• Use typescript files - no need to transpile it happens on the fly.
• Faster loading time.
• Blazing fast request processing.
• Binary lock file.

I've created a few projects with Bun, and the process - building, testing, and producing - was fast and efficient.

📝 Developemnt

I can chip in and create the Bun open runtime.

Thank you for this feature idea!

Looping in @Meldiron for feedback on this

I've just run a few benchmarks comparing the results of the same code in Bun vs. Node19 runtime.

The results are implacable; a table here represents the results of the K6 benchmark. (thanks to @Meldiron for that one)

Paramter	Bun	Node
Max VUS	5,000	5,000
http_req_connecting	1.47µs	2.58µs
http_req_duration	60.07ms	177.12ms
http_req_waiting	60.32ms	177.11ms
http_reqs	2,499,396	857,188
Per second	27,769	9,523

Both tests ran for 90 seconds using a Stress testing method.

export const options = {
 stages: [
   {duration: '30s', target: 20},
   {duration: '10s', target: 5000},
   {duration: '20s', target: 10},
   {duration: '10s', target: 5000},
   {duration: '20s', target: 0},
 ],
};

I've uploaded a pull request of the Bun runtime in a ready-to-use state to be checked when ready.

Thanks
