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:

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 am trying to solve that error and I spent hours trying to fix it. I updated all my dependencies from a project that used material-ui , so I migrated to @material-ui/core because the first is deprecated. I have a copy of that project (No code changes) and in the non-updated project I don't get the error.
When I updated everything I got the follow error:
Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.
Here is my class:

QUESTION
I have an application with a table, the table has a checkbox to set a Tenant as Active, this variable is a global variable that affects what the user does in other screens of the application.
On the top right of the application, I have another component called ActiveTenant, which basically shows in which tenant the user is working at the moment.
The code of the table component is like this:
...ANSWER
Answered 2019-Feb-27 at 14:42You're not using redux correctly there. You need to keep somewhere in your redux state your active tenant; That information will be your single source of truth and will be shared among your components throughout the app. Every component that will need that information will be connected to that part of the state and won't need to hold an internal state for that information.
Actions, are where you would call your API to get your active tenant information or set a new tenant as active. These actions wil call reducers that will change your redux state (That includes your active tenant information) and those redux state changes will update your app components.
You should probably take some time to read or re-read the redux doc, it's short and well explained !
QUESTION
My react app has a component called ListOfTenants, which is basically a table with a radiobutton on each row. And eevery time a row is selected, I want that in the top bar navigation, there should be a component that says, You are working on tenant X.
So the ActiveTenant component is like this:
...ANSWER
Answered 2018-Aug-06 at 11:07If you're using React 16, you could make use of the new Context API
In a typical React application, data is passed top-down (parent to child) via props, but this can be cumbersome for certain types of props (e.g. locale preference, UI theme) that are required by many components within an application. Context provides a way to share values like these between components without having to explicitly pass a prop through every level of the tree.
