tea.xyz Spam Plagues npm and RubyGems Package Registries
Tea.xyz, a crypto project aimed at rewarding open source contributions, is once again facing backlash due to an influx of spam packages flooding public package registries.

Readme
Check out the documentation for complete integration instructions.
First, install the plugin @codspeed/tinybench-plugin
and tinybench
(if not already installed):
npm install --save-dev @codspeed/tinybench-plugin tinybench
or with yarn
:
yarn add --dev @codspeed/tinybench-plugin tinybench
or with pnpm
:
pnpm add --save-dev @codspeed/tinybench-plugin tinybench
Let's create a fibonacci function and benchmark it with tinybench and the CodSpeed plugin:
import { Bench } from "tinybench";
import { withCodSpeed } from "@codspeed/tinybench-plugin";
function fibonacci(n) {
if (n < 2) {
return n;
}
return fibonacci(n - 1) + fibonacci(n - 2);
}
const bench = withCodSpeed(new Bench());
bench
.add("fibonacci10", () => {
fibonacci(10);
})
.add("fibonacci15", () => {
fibonacci(15);
});
await bench.run();
console.table(bench.table());
Here, a few things are happening:
We create a simple recursive fibonacci function.
We create a new Bench
instance with CodSpeed support by using the withCodSpeed
helper. This step is critical to enable CodSpeed on your benchmarks.
We add two benchmarks to the suite and launch it, benching our fibonacci
function for 10 and 15.
Now, we can run our benchmarks locally to make sure everything is working as expected:
$ node benches/bench.mjs
[CodSpeed] 2 benches detected but no instrumentation found
[CodSpeed] falling back to tinybench
┌─────────┬───────────────┬─────────────┬───────────────────┬──────────┬─────────┐
│ (index) │ Task Name │ ops/sec │ Average Time (ns) │ Margin │ Samples │
├─────────┼───────────────┼─────────────┼───────────────────┼──────────┼─────────┤
│ 0 │ 'fibonacci10' │ '1,810,236' │ 552.4139857896414 │ '±0.18%' │ 905119 │

└─────────┴───────────────┴─────────────┴───────────────────┴──────────┴─────────┘
And... Congrats🎉, CodSpeed is installed in your benchmarking suite! Locally, CodSpeed will fallback to tinybench since the instrumentation is only available in the CI environment for now.
You can now run those benchmarks in your CI to continuously get consistent performance measurements.
