How to make redux TodoMVC example a real-time multiuser app with nun-db in 10 steps
In this tutorial, we will show how to add Nun-db to an already existent react/redux app. This project is a copy and paste of https://github.com/reduxjs/redux/tree/master/examples/todomvc + adding Nun-db as a database that makes it real-time and durable.
We need to make little archive that goal. (And I also believe this is true for any other Redux like projects)
Checkout it in action
Next I will list the changes we have made.
1. Clone redux samples
git clone email@example.com:reduxjs/redux.git
2. Go to the examples folder
3. Install all modules
4. Start the dev app
At this point, the app with be running without any persistence. If you reload the app, add data come back to the default state. Now the fun starts.
5. Run nun-db server in docker
In a different terminal
docker run --env NUN_USER=user-name --env NUN_PWD=user-pwd -it --rm -p 3013:3013 -p 3012:3012 -p 3014:3014 --name nun-test mateusfreira/nun-db
6. Create the nun database
Now back to the js project.
7. Installed Nun-db in the project
npm install nun-db
8. Added Nun-db middleware
Use your favorite text editor,
Add the next code to the file
9 Added Nun-db middleware to the store in the index.js
Reload the page and check the network console tab to make sure the database connected as expected.
10. Add event to update all the state in the first load
Done your app is already working with Nun-db. Now to see the magic happening, open the same page in another computer or browser to see how changing one place will reflect immediately in the other. In summary, all you need is the following changes (git diff).
And adding the nun.js to the
src folder as shown in this post…
This is all I did, and now the app is real-time, durable, and with minor changes to the code. I hope it helps you to do the same on your app. If not, don’t leave us an issue. We will be happy to make it work on your app.
