Event Replay: If we find a past event was incorrect, we can compute the consequences by reversing it and later events and then replaying the new event and later events. (Or indeed by throwing away the application state and replaying all events with the correct event in sequence.) The same technique can handle events received in the wrong sequence - a common problem with systems that communicate with asynchronous messaging.

make the Compose file the source of truth for development and deployment

As a reminder, the JSON Schema is not the source of truth for the Specification. In cases of conflicts between the Specification itself and the JSON Schema, the Specification wins.

As a reminder, the JSON Schema is not the source of truth for the Specification. In cases of conflicts between the Specification itself and the JSON Schema, the Specification wins. Also, some Specification constraints cannot be represented with the JSON Schema so it's highly recommended to employ other methods to ensure compliance.

Oh, I just figured out a workaround for my project, in case it helps someone. If you want the source of truth on the prop to come from the child component, then leave it undefined in the parent. Then, you can make the reactive variable have a condition on the presence of that variable. eg: <script> let prop; $: prop && console.log(prop); </script> <Child bind:prop/> Might not work for every use case but maybe that helps someone.

withindex.js, we have a single source of truth, giving fine grained control on what we expose to the outside world.

In the next major, we'll start copying the ref onto both the props and the element.ref. React will now use the props.ref as the source of truth for forwardRef and classes and it will still create a shallow copy of props that excludes the ref in these cases. At the same time, we'll add a getter for element.ref in DEV that warns if you access it. The upgrade path is now to just access it off props if you need it from the element.

Redux, which features a single store, often called a single source of truth

Do not include the same information in multiple places. Link to a SSOT instead.

There is a temptation to summarize the information on another page. This will cause the information to live in two places. Instead, link to the SSOT and explain why it is important to consume the information

With a single file in the repository, everyone with read access can see the contents, making it much more inviting to improve and review the build scripts.

Code Owners allows for a version controlled single source of truth file outlining the exact GitLab users or groups that own certain files or paths in a repository.
