Connecting MongoDB Atlas

connectingMongoDB.md

Here's how to create a free cluster and connect it to your project using the connection string

1. Create an account on MongoDB Cloud Atlas
2. You will be prompted right away to create a new project and org. You may leave all values as default and click Continue.
3. Three cards will show up next asking you to choose a cluster. Select the Shared Cluster - that's the one which is free.
4. The next screen is about details of the cluster. Make sure M0 Cluster Tier is selected. You may leave all values as default and click on Create Cluster
5. Wait for some time for the cluster to get ready and then click on Connect.
6. First thing you need to add it IP Address. Select Add your current IP Address if you are working on the project yourself only or Allow Access from Anywhere. You may even manually add IP Addresses by clicking on Add a different IP...
7. Next up is Database user creation. You need to enter a username and password. For explanatory purposes, say I added them as admin and pass respectively.
8. Next step asks you for a connection method. Select Connect Your Application and then copy the connection string that gets prompted and click close. You may even close your browser as you do not need to do anything further through the website.
9. Now open your project and create a .env file in the directory of your backend application and add a key value pair as follows: MONGO_URI=<paste your connection string that you copied>

The string looks like this: mongodb+srv://admin:<password>@cluster0.bqss1.mongodb.net/<dbname>?retryWrites=true&w=majority

In the connection string as shown above, you need to replace <password> with the password you had created in step 7 and <dbname> with a name that you would like to name your database.

So it would finally look like this for me (with username: admin, password: pass, dbname: todo) mongodb+srv://admin:[email protected]/todo?retryWrites=true&w=majority

Do i Upload it to github?

@zcy764 use environment variables to store secrets like mongo uri and make use of gitignore to prevent them getting pushed to GitHub.
