## About Trigger.dev
Trigger.dev is an open source platform and SDK which allows you to create long-running background jobs. Write normal async code, deploy, and never hit a timeout.
### Key features:
- JavaScript and TypeScript SDK
- Write reliable code by default
- No timeouts
- Retries (with exponential backoff)
- Queues and concurrency controls
- Schedules and crons
- Full Observability; logs, live trace views, advanced filtering
- Custom alerts, get notified by email, Slack or webhooks
- No infrastructure to manage
- Elastic (scaling)
- Works with your existing tech stack
## In your codebase
Create tasks where they belong: in your codebase. Version control, localhost, test and review like you're already used to.
```ts
import { task } from "@trigger.dev/sdk/v3";
//1. You need to export each task
export const helloWorld = task({
//2. Use a unique id for each task
id: "hello-world",
//3. The run function is the main function of the task
run: async (payload: { message: string }) => {
//4. You can write code that runs for a long time here, there are no timeouts
console.log(payload.message);
},
});
```
## Deployment
Use our SDK to write tasks in your codebase. There's no infrastructure to manage, your tasks automatically scale and connect to our cloud. Or you can always self-host.
## Environments
We support `Development`, `Staging`, and `Production` environments, allowing you to test your tasks before deploying them to production.
## Full visibility of every job run
View every task in every run so you can tell exactly what happened. We provide a full trace view of every task run so you can see what happened at every step.
# Getting started
