QUESTION
I'm currently working on a chat app for school, but I want to make it scroll to the bottom automatically as most chat apps do. I've tried every solution I can find so far, and I have only been getting react errors. I'm new to react so there could be some mistakes I don't realize I'm making. Here is what I have

The chatbox content need the following markup, where the content is aligned to bottom.

QUESTION
I am trying out some stuff using the react-chatbot-kit in the front end and getting data from a REST API. Console.log shows the data inside .then, however I am getting the error "Uncaught TypeError: Cannot read property 'map' of undefined" when trying to output the data on the console inside the calling function. I need help to display the returned data in console.log in the function handleApiList(). Thanks in advance.
PS: I am a newbie of course in React :) since I am not clear on how to handle REST API calls that are done asynchronously. Look forward to getting this resolved. Any help and tips on resolving this will be greatly appreciated
Following is the code:

Answered 2020-Nov-23 at 13:04You are fetching in getData and it's an async function. The data is not ready. It's better to just return the data than to setting state.

QUESTION
I want to create line chart with chart.js and it needs data with an array.
And I want to create a chart of post views by date. The range was set based on one week, and counters collection was created in MongoDB.
One week is 7 days so I use for loop to query seven times and get each counter value. The results are fine. And there is no problem with frontEnd side but sometime server send wrong data.
DB Data
...ANSWER
Answered 2020-Oct-22 at 11:04I guess that's because you're running an asynchronous block of code inside a for loop
try using async/await to force the for loop to wait until the asynchronous block of code executes and resolves its result before getting into the next iteration
so you code may look something like

QUESTION
I have this react app I want to dockerize. But the problem is, even though I tried, it doesn't work. But it works pretty well locally
This is how the current directories look like:
...ANSWER
Answered 2020-Sep-18 at 09:09Firstly, make sure you are copying the same package-lock.json file that you use to install deps locally, to make sure you have the same dependency tree in your container as you do locally.
COPY package.json package-lock.json /app/
Then, make sure that you are matching the same node/npm version as you run locally (replace 12 with the major version you are running, be it 10, 12, 14 or whatever):
FROM node:12
Each node version is bundled with a specific npm version (latest 12 version comes with npm 6.14.6), you can find the bundled NPM version int he changelogs, https://github.com/nodejs/node/tree/master/doc/changelogs
Additionally, instead of running npm install, you might wanna run npm ci in the container. The latter skips any checks for discrepancy between the lock file and your package.json file and just installs the locked dependency tree, which is not only faster, but will also match your local dep tree exactly.
EDIT:
In addition, this line:
COPY . /app
Would also overwrite node_modules unless you have ignored it via .dockerignore or similar.
Easiest would probably be to add a .dockerignore file to the same folder as your Dockerfile and add lines stating:
QUESTION
I'm trying to use components from dependencies in a project mostly freshly forked from electron-react-boilerplate. The layout is messed up (see pic below). Tried react-chat-window, react-chat-widget, and react-datepicker, so it's across the board. Sorry if this is vague, but I don't know what else to say, and I'm hopefully missing something really basic. Anyone know?
I've also read the electron-react-boilerplate docs. My deps are in ./package.json as suggested, but I also tried putting them into ./app/package.json, which breaks it entirely. This SO answer about material-ui didn't help this either.
Here's the relevant part of my page component, pretty much the same as in the example for react-chat-window:
...ANSWER
Answered 2020-Aug-09 at 15:36This page on electron-react-boilerplate, which seems to only be findable via Google and not on their site, pointed me to edit app.global.css. Seems really wrong that I have to do this when the module already imports its own styles, but it worked:
Replaced the contents of app.global.css with:
QUESTION
So, I'm making a small chat tool using react-chat-elements as UI library for chat components. I'd like to modify certain CSS values to match what I want to build without being tied to that specific library the way it is now (it hasn't been updated since 5 months ago).
So what I tried is fork it to my Github account, created the NPM package from it (react-chat-elements-av) without making any changes first to make sure it worked the same way as with the original. However, when I import a specific component from the NPM package I created, say import { MessageBox, SystemMessage } from "react-chat-elements-av";, I get an error saying Attempted import error: 'MessageBox' is not exported from 'react-chat-elements-av'., being the attempted import location: /node_modules/react-chat-elements-av/index.
Now, if I import those two components from the original NPM package, import { MessageBox, SystemMessage } from "react-chat-elements";, everything works and the import location is a bit different: /node_modules/react-chat-elements/dist/main.
Is there something I'm missing on the creation of that dist directory when doing npm install react-chat-elements-av? I literally forked the original repo, and created the NPM package with it, no changes made to any webpack config or so.
Any idea what could be happening here?
Thanks in advance!

Answered 2020-Apr-04 at 21:53The dist repository is for production grade code after it has been built. It's the distribution file. try seeing how they have built their library by running npm run build once you've downloaded it.
QUESTION
I've been trying to deploy my full-stack chatkit messenger app from localhost to being in production with Heroku. I'm not sure which changes have to be made within my code for it to run properly on heroku, as I'm currently getting a 404 "Not Found" error.
I've added a Procfile and an App.json file as someone recommended. I'm not sure whether my package.json's Start scripts are to blame, or whether I need to update the URL's of the HTTP requests within my code (from localhost to heroku's site url).
Or if I need to push the app to production and download static files, which I'm not very experienced with. The code is hosted on my Github (https://github.com/aladin94/MyChatterbox). What am I doing wrong?
...ANSWER
Answered 2020-Mar-04 at 05:21Try to put the build at the root of the project and change the code to:
app.use(express.static('build'))
app.get('*', (req, res) => {
res.sendFile(path.resolve(__dirname, 'build', 'index.html'))
})
To run the build, you need to add scripts to the package.json: "build": "react-scripts build"
Change your static routes http://localhost:3001/users to "/users", as the back-end and front-end are on the same server.
QUESTION
I am a newbie, and am trying to build a simple restaurant recommendation web app using AWS and React. So, I am using this chat window(https://www.npmjs.com/package/react-chat-window). Basically, when the user types something, the chatbot gets triggered and asks questions like "what kind of food do you want?" So far, I am able to pass the user's input and get the response back from the AWS. I can log the response to the console and verify it. But I have trouble getting the response displayed in the chatbox.
Here is the snippet of the code
...ANSWER
Answered 2020-Feb-21 at 05:09You have to bind your class methods in class components in order to call them with this. But you have to do this, e.g. in the constructor BUT not in your render function!
Check out this very nice explanation on why and how to bind your functions.
