What is Hatchet?

Hatchet replaces difficult to manage legacy queues or pub/sub systems so you can design durable workloads that recover from failure and solve for problems like concurrency , fairness , and rate limiting . Instead of managing your own task queue or pub/sub system, you can use Hatchet to distribute your functions between a set of... See more

Shipping to production

Before shipping to production, we think about all the different artifacts that might be affected by a new feature.

Here's a non-exhaustive list of things we ask ourselves:

• Does the API need to be updated?


• Is the OpenAPI spec up to date now?


• Have we released all the official SDKs?


• Do we need to write a Changelog post to announce

Comments are helpful sometimes. But sometimes, they are just an indication of bad code.The proper use of comments is to compensate for our failure to express ourself in code [1].Whenever you have to add a comment in your code, ask yourself if it is really required or if you could instead put that into a new function and name the function so that it...

Problem : Tight coupling leads to fragility - a change in one microservice breaks connected services.

Low cohesion results in unclear responsibilities.

• Solution : Apply loose coupling and high cohesion. In a loosely coupled system, each component is independent and changes in one will not affect the others. High cohesion means that each component

When a test fails, you should be able to begin investigation with nothing more than the test’s name and its failure messages —no need to add more information and rerun the test.

Effective use of unit test frameworks and assertion libraries (JUnit, Truth, pytest, GoogleTest, etc.) serves two important purposes. Firstly, the more precisely we express... See more
