            Normal/Standard way to compare prevProps in componentDidUpdate
            Asked 2020-Jun-18 at 13:44

            This has come about because during prototyping, I'm finding that incoming new prop(s) might be an array of complex objects, so prevProps.myProp===this.props.myProp is always false. JSON.stringifying them both before comparison works, but feels unreliable.

            I'm trying to write a reusable function for Class Components that compares prev/new props in react's componentDidUpdate. For example:

            ...

            ANSWER

            Answered 2020-Jun-18 at 13:44

            that would mean any time the incoming props change, those get immediately reflected in state

            Yes, that's wrong. When I first started out I was doing the same thing.

            1. state is something "owned" by that component (noteworthy: not all components need state at all!).
            2. props are something that are "owned" by a higher component.

            Best example:

            ComponentA passed an id to ComponentB as a prop. ComponentB uses that id to make an API request (for example).

            The status/results of that API request form part of ComponentB's state (it's "owned" by your component). The id passed in as a prop is NOT part of ComponentB's state (it's owned by ComponentA, or maybe somewhere higher in the tree that passed it as a prop to ComponentA).

            When the id prop changes, ComponentB will need to make another API request.

            EDIT:

            The complexity of lifecycle methods is why React has highly encouraged functional components.

            You should think of components as functions. It's a lot easier to write the logic if you just think of it as input -> output.

            componentDidUpdate has been moved to useEffect with a dependency list so you can say - run this function, but only when this prop changes - which is a nice way to break down massive componentDidUpdate methods into tiny readbale/testable chunks.

            I've heard a lot of people say hooks ruined react, but I highly disagree with them. React saw the problems people were running into in the community by misusing class/instance based components and instead of lecturing about how to use them correctly, they nudged people to writing better components by introucing a simpler API - functions, while they still can and will be abused - are generally simpler to deal with than classes and align nicely with composition over inheritance and declarative over imperative.

            Serialize but not deserialize fields/properties in XML, JSON and (particularly) YAML?
            Asked 2018-Jun-17 at 13:15

            I have a set of objects that contain fields & properties that need to be inspectable in the output of serialization but not read back in when deserialized.

            This is purely for debugging/confirmation purposes. We are creating hundreds of files and I want to spot check that serialization is occurring correctly by adding supplementary information. I do not want this supplementary information to be read in during deserialization - it's impossible to do so in fact.

            I also need to do this with equal facility across different serialization formats, so we can assess which one is working best. I have a generic serialization approach where the desired format is passed in as an argument, so don't want anything too messy or intricate for each different format.

            I've hunted around and found various things on related topics - mostly to do with the opposite: not writing certain fields during serialization. What's out there seems to be quite complicated and at times hacky.

            Is it possible to serialize an object differently to deserializing it using Json.Net?

            JsonConvert .NET Serialize/Deserialize Read Only

            Serialize Property, but Do Not Deserialize Property in Json.Net

            Also it appears any approach is inconsistent between serialization formats. i.e. unlike the [*Ignore] attributes, there are no [*SerializeOnly] attributes (where * = JSON, XML, YAML).

            Is there an easy way to do this across these serialization formats? Is there a single family of attributes that can help? Or is it idiosyncratic and hacky in each case?

            Javascript arrays and objects: Get differences and merge them
            Asked 2017-Oct-19 at 15:42

            So I have this scenario where I have a client-app which sends data (array of objects) to a server which then forwards the data to other clients connected to this server.

            In the client-app, the data is constantly changing, meaning: Values change, new objects inside the array pop up, objects being removed, and so on ...

            Now I want the other clients to always receive the latest data. And because I dont want the client-app to just push the whole new data to the server which then forwards the whole new data to the other clients, I decided to let the client-app only push the changes (using this library: https://www.npmjs.com/package/deep-object-diff).

            The other clients then receive an array of objects with only the data that has actually changed and because they know the previous data array, I want them to "merge" the array of changes with the old data object.

            My actual problem is the merging. I dont know how to properly do this. Especially if I have an array of objects without any key for the objects.

            Answered 2017-Sep-27 at 20:14

            The library doesn't export anything. It uses IIFE to not pollute global scope with local variables. It's impossible to reach local variables from the outside, this makes Module pattern so effective (and annoying).

            The library uses AngularJS angular global and expects that it will exist. This creates a problem, because Angular 4 application should mock angular global in this case. Moreover, the code itself relies on AngularJS-specific units ($sce service).

            The library should be forked and modified to suit the expectations. The mentions of angular should be removed. Considering that script will be executed in module scope, IIFE should be removed and appropriate exports should be added.
