This is the same sample web app deployed on
The Sample Web App is hosted on Render.com, a cloud-based application hosting platform with the following components:
Frontend: HTML, CSS and Javascript
Backend: NodeJS, Express, EJS
Database: Postgres
You will need to be signed in to GitHub and Render.com before you setup the Sample Web Application. For instructions on how to sign up for a GitHub and Render account respectively, please refer to the following pages.
Type in your own repository name (this could be any name)
The description for your repository can be empty
Your repository should by default be Public
Ensure that you check the "Add a README file"
Ensure that you select Node as the .gitignore template
The license can be at it's default setting of None
Note that your default branch may be called "master" or "main", this is okay and you can leave it (mine is currently set as "develop").
Click on "Create repository" to create your new GitHub Repository
You should have been re-directed to your newly created repository
Click on the green "Code" button, select the "Codespaces" tab and click "Create Codespace on develop". (Note: your branch may be called "master" or "main" and this is fine)
Your GitHub Codespace should have opened up in a new tab after creating a codespace in the previous step.
After completing Step 2, a new tab should have opened with your Codespace similar to the image shown below.
Drag and drop all files and folders in Step 3 into the sidebar of your Codespace. IMPORTANT: Ensure that you select all the files and folders INSIDE the unzipped file, do not upload the whole zip file (see the below images if you are unsure).
This uploads the sample web app source code to your Codespace
After dragging and dropping, your Codespace should look like this with the following files in the sidebar
Click on the Source Control icon (the icon which has blue numbers on it, in the image above it's the third tab on the left)
Enter a commit message of "Uploaded sample code"
Click on the dropdown next to "Commit" and click on "Commit & Push".
Note that you will have to click on the drop down arrow for "Commit & Push" to show up
If the following pop-up appears, select "Always"
Another pop up may appear at the bottom right of your screen, select the option of "Yes"
Check that your files are in your GitHub repository by going to https://github.com and selecting the repository you created in Step 1
You should now see that there are the newly uploaded files in this repository
Type in a Name for your PostgreSQL instance (I've named mine techup-sample-database)
Leave the Database field blank
Leave the User field blank
Change the Region to "Singapore (Southeast Asia)
Leave PostgreSQL Version as the default value of 16
Leave the Datadog API Key field blank
Change your instance type to FREE
Click on "Create Database"
Your database should now be created (after about 30 seconds)
Scroll down to the section on Connections and take note of the External Database URL
Copy this External Database URL to a blank word document (or anywhere else such as Notepad) as you will be using it later to add it as an environment variable.
IMPORTANT: PLS ENSURE YOU HAVE COPIED THIS URL AS YOU NEED IT LATER.
Ensure "Build and deploy from a Git repository" is selected then click Next
On the right column you will need to click on "+ Connect Account" to connect your GitHub account to Render.
Click on "Connect" for the repository name which your created in Step 1
Leave the Name field as it's default value
Ensure that the Region is set to "Singapore (Southeast Asia)"
Ensure that your Branch is selected (yours may be called "master" or "main")
Leave the Root Directory field blank
Leave the Runtime as "Node"
Change the Build Command to yarn; npx prisma db push; npx prisma generate
Add the Start Command of node server.js
Change the Instance Type to FREE
Click on the "Create Web Service" button to start deploying
You will be redirected to a new page which shows the logs of the server build happening. It would take approximately 2-4mins for the the server to full deploy your app.
Your app is deployed once you see the line "==> Your service is live 🎉" in the logs.
You should now be able to view the sample web app which you have deployed on your own Render server!
Have fun playing around with the sample web app by Adding and Deleting blog posts!
External Database URL (which you copied earlier when setting up Postgres) into the text field then click ImportIf you prefer to watch a video of this setup you may watch it instead.
Go to to create a new repository
Go to to create a new PostgreSQL database on Render.
Go to to create a new Web Service (alternatively you may also click on the purple New + button at the top of the page and select Web Service)
Add a new Environment Variable of name DATABASE_URL with the value of your copied External Database URL in Step 6. (If you have misplaced this URL, not to worry. Go to and click on your database. Scroll down and simply copy the External Database URL again.)
At the top of the same deploy page with the logs, you will see a URL (in my case it is ). Click on this link and it will bring you to your web application.
