QUESTION
The question is simple. How to fetch data in your React blog and stay DRY? Let's say that you have just two components in your blog - PostsList and SinglePost, in both components you must fetch data, activate isLoading state, etc. There will be chunks of the same code in both components.
I investigated the situation a little bit, checking React-blog demo apps of big headless CMS providers, like Prismic or Sanity.io, and they all just repeat fetch functions in both PostsList and SinglePost.
Does anybody have any idea? You can point me to some good resources?
...ANSWER

QUESTION
I don't know much about React and I have to test an application made in React.
My problem comes when I try to run the server with gulp nodemon, and I get a lot of errors. Apparently the application is built on an old version of React and doesn't recognize some libraries or modules; I have already solved several of them regarding prototypes or the way a ReactClass is created, but I found one regarding Bootstrap that I haven't been able to solve.
This is the error I get:

From this issue. The fix is to use the prop-types package instead

QUESTION
Getting: Build script returned non-zero exit code: 1
I have deployed my react js website code through Netlify and getting a build log and error as follows:
...ANSWER
Answered 2018-Sep-26 at 21:33The issue here is caused by the build environment using react-scripts in your create-react-app. You have a node_modules package being imported that is in an unexpected bundle format.
When running your npm run build in local development, which is what is happening on Netlify, you will see the following error on your build:
QUESTION
I have a simple blog that i'm developing using create-react-app (using react-scripts@next to get CSS Modules support).
The problem i'm having is the CSS hover transitions are very laggy and slow. I previously implemented this interface using Node EJS templates and everything was snappy and fast.
I'm thinking the problem maybe has to do with the PostSummary component receiving new props and re-rendering constantly, but all the props appear to be static once they're loaded.
I checked the Chrome performance tab and it said the majority of the cycles were being used by paint time (and not load time).
Very confused, anything I can test to resolve the issue?
...ANSWER
Answered 2018-Aug-11 at 20:35Animating large images will cause performance issues. The first image in your example is: width: 5264px; height: 3393px;. Optimize the images for web and they should load quicker and animate smoothly.
Consider animating text and pure HTML elements, but try to avoid animating large images.
When you resize an image by transitioning it has to render the image multiple times during the transition and is very "expensive".
QUESTION
I am trying to make a simple React blog app with MongoDB storing the posts, but webpack won't compile when I try to import a Mongoose model into my NewPost component.
Here are the errors:
...ANSWER
Answered 2018-Jan-08 at 00:11The problem you have is that you're mixing client (React) and server side code (Mongoose). While both of them are JS, Mongoose relies on some built-in Node.js modules and Webpack can't resolve those modules, unless your target is node which it will ignore them (You can learn more about it here).
I see what you were trying to do, call Mongoose models from your React components and fetch data from there, right?... that's not the way it works.
The solution here would be removing those Mongoose models, separate your code (client/server), make an API and handle all your needs from there (Create, Read, Update, Delete all your resources), here's a video tutorial that will help you to create an API really quickly using node-restful but just for demo/practice purposes and this other one for fetching data (an easy and simple way).
QUESTION
I am very new to unit testing, and am trying to go through my react-redux project to write some tests.
Why is this test not working, and how could I make it pass?
Here is the test. I want to test my fetch posts action creator. This is for a small blog application.:
...ANSWER
Answered 2018-Feb-08 at 08:15The mocked store you are using will store all dispatched calls that have been made to it. In your case, two dispatch calls should be made, the first being FETCH_POSTS and the second being either FETCH_POST_FULFILLED or FETCH_POST_REJECTED.
Hence when you retrieve the dispatched actions from the mocked store, the first entry (which you are using in your expect) will be the FETCH_POSTS. You should check the second value in the array, which would be either FETCH_POSTS_FULFILLED or FETCH_POSTS_REJECTED based on how the promise is resolved in the function you are testing.
QUESTION
I am trying to make a simple signup form. I have a redux form that I'm trying to send some user data to my express backend with. I am trying to do this through redux actions via this redux action:
Ultimately, I'd like to receive a response, and redirect or give errors if necessary. The backend seems to receive the data and can validate, but axios receiving the response to let redux know to update the state. Any ideas?
Edit: I also tried putting the axios request inside of the signupForm itself, and still had issues(wasn't able to get a response).
Edit: Here is the repo if you'd like to see all the files: https://github.com/capozzic1/react-blog
redux signup action:
...ANSWER
Answered 2017-Aug-30 at 04:36It doesn't work because your anonymous function returned by signUp function returns a promise. Use brackets to avoid default behaviour.
