`

$3

- simple task executor

`typescript
import { taskPoolExecutor } from "task-pool-executor";

const executor = taskPoolExecutor({ maxConcurrent: 3 });
const task = {
title: "my-task",
run: () => Promise.resolve("done"),
};
executor.submit(task);

await executor.close();
`

- with cli progress support

`typescript
import {
CliProgressRunContext,
cliProgressTaskPoolExecutor,
} from "task-pool-executor";

const taskPool = cliProgressTaskPoolExecutor();

const delayedTask = (millis: number, title: string) => {
const run = (ctx?: CliProgressRunContext) =>
new Promise((resolve) => {
const interval = setInterval(() => {
ctx?.progress.increment();
}, 8);
const timeout = setTimeout(() => {
clearInterval(interval);
resolve("done");
}, millis);
});
return { title, run };
};

const tasks = new Array(10)
.fill(0)
.map((_v, index) => delayedTask(2000, task ${index}));

const internal = async () => {
tasks.forEach((t) => taskPool.submit(t));
await delayedTask(8000, "running").run();
await taskPool.close();
};

internal().then(console.info).catch(console.error);
