How to deploy Puppeteer with node on Render.com

Hello everyone, today I want to share my experience with everyone it’s a very challenging to deploy puppeteer on render because after a lot of search and I did not find any solution and chatgpt as well failed to give me a complete and proper solution after 3 days a lot searches I found the solution and successfully deploy my puppeteer node app on render. Today we will discuss how to deploy apps on render. I’ll try to explain everything in this post.

Hopefully this will be in your code as well and I had the issue when I deployed my app on render then on the “Launch” line my code was broken and said that chrome is not supported on it.

My package.json file. Install the puppeteer latest version

After that create a new file with the name of “render-build.sh” on the root of the project. Like that

In the “render-build.sh” file Add these codes.

#!/usr/bin/env bash
# exit on error
set -o errexit

# Install dependencies
npm install
# Uncomment this line if you need to build your project
# npm run build 

# Ensure the Puppeteer cache directory exists
PUPPETEER_CACHE_DIR=/opt/render/.cache/puppeteer
mkdir -p $PUPPETEER_CACHE_DIR

# Install Puppeteer and download Chrome
npx puppeteer browsers install chrome

# Store/pull Puppeteer cache with build cache
if [[ ! -d $PUPPETEER_CACHE_DIR ]]; then 
  echo "...Copying Puppeteer Cache from Build Cache"
  # Copying from the actual path where Puppeteer stores its Chrome binary
  cp -R /opt/render/project/src/.cache/puppeteer/chrome/ $PUPPETEER_CACHE_DIR
else 
  echo "...Storing Puppeteer Cache in Build Cache"
  cp -R $PUPPETEER_CACHE_DIR /opt/render/project/src/.cache/puppeteer/chrome/
fi

This is the screenshot of the code.

After that push these changes to the github and then go to the render dashboard and add the build command to the render dashboard. Go to your service and then go to the Environment tab and then scroll down to the build section and add the line.

“./render-build.sh”

After adding just save and deploy again your changes. Now hopefully your changes will be deloyed and puppeteer will work successfully. If you face any route issue in the logs like

Said that any route issue then check your logs and if your opt routes is not match this below route then change your render-build file route and push changes and deploy again.

Hopefully this post will be helpful for you. If you face any issue please comment below I’ll try to help you.

Thanks
