Agile teams are often confused between Acceptance Criteria (AC) and Definition of Done (DoD), if you are one of them, you are at the right place. What is the Definition of Done (DoD)? Definition: A shared team-level checklist ensuring work is fully completed and ready for release. Ensures consistency, quality, and alignment across the team. Applies to all user stories, features, and increments. Example of a DoD checklist: Code is written and peer-reviewed. Unit and integration tests are passed. Security checks are completed. Documentation is updated. What are Acceptance Criteria (AC)? Definition: Story-specific conditions that must be met for a user story to be considered successful. Written from a business or user perspective . Can vary between user stories. Example of AC for a login feature: The user must enter a valid email and password. If incorrect credentials are entered, an error message should appear. If correct, the user is redirected to the dashboard. Key Differences Betwe...
Node Js - Valid JSON body before it reaches API router endpoint "SyntaxError: Unexpected string in JSON at position 83
at JSON.parse"
When using node js with express, sometimes we get some unexpected errors from the API endpoint which doesn't really makes sense to the API consumer. On the other hand, we need to send appropriate message and Http Code to the consumer. If you pass invalid Json body to a node Js API, you may get the following enexpected error. " SyntaxError: Unexpected string in JSON at position 83 < br > at JSON.parse" We can clearly see, such errors can't be handled accurately by the consumer application as it has lot of HTML data as response. To fix this, you can try to handle the parser error in the router endpoint and return apropriate message to the consumer, but there is an issue, the middleware itself returns the above error to the consumer, before it reaches the API end point. So, the solution is pretty simple and will be applicable to all the APIs. Write a middleware to handle this error like following. const app = ex...
