LinkedIn Reaction Poll Generator(Beta)

Reactions increase the reach of a post on LinkedIn similar to what happens on every other social media platform. Because of this, something I call “reaction polls” have become really popular as a growth hack. Instead of running a regular LinkedIn poll, which is frankly pretty jank and constrained to 4 options, you can have users react to your post to vote on the option they want, creating a much richer experience that also nets you the poster a bunch of free engagement. If you don’t know what I’m talking about, here’s an example of one of these reaction polls:

This project is an implementation to the idea here by Alex Chiou.

Using the app will output an image that is 540px wide for Linkedin feed:

Running it Locally:

Clone this project to your computer and cd into the project. Run yarn install (you can also do npm install, but yarn seems to download everything quickly, since we already have a lock file).

Run this project by typing yarn start and visiting localhost:3000 on your computer.

Edit the App.js file, it’s a single file with all the HTML and JS for the time being.

Edit the App.css file to style the app.

MVP Requirements (implemented)

• Show an initially blank image with the 5 LinkedIn reactions. This will be the “canvas” that lets users know what their reaction poll currently looks like.
• User can type in what question they want to poll to ask. The “canvas” should update in real-time.
• User can type in the text they want to show up for each of the reactions. The “canvas” should update in real-time.
• User can click a button and download the filled in template image when they are done.

How it is done?

Using <canvas> API it’s possible to draw text over images like we see meme generators. But implementing the raw API is cumbersome. Fortunately there a are bunch of open source tools that let us make it easily. I used the Dom To Image package to handle the image generation. I was surprised it created the image without any visible inconsistancies.

I created a preview or demo area where we will put all the text and icons. When we click download domtoimage will take that entire element by the class and offer to save. The save function is achieved using another package called File Saver

The main interactivity is done using ReactJS with local state.

Todo List

• Add the 6th remaining icon, Support.
• Add option for image uploads for each votes.
• Variable text size for legibility.
• Need to make this app usable on the mobile. Right now it’s not very friendly, because it’s best fit as a desktop app.
• Implement accessibility.
• Browser testing.
• Need to fix bugs after user testing.
• A reset button to clear all the text.
• Refactor the code.
• Add a button to directly post to linkedin.
• Title uppercase, lowercase, capital case options.
• Dark mode.
• Color options.
• Save the last image data into the user’s browser.
• Implement image loading skeleton for layout shifts
• Other extensions mentioned here

Done

• Bought domain name
• Add google analytics for page views and custom events for image download button clicks.
• Add github star button.
• Better layout so we can see the text while editing.
• Want to implement high-resolution image outputs. At least 800-1200px. (made the image 800px)
• What happenes when we add a long title and long option names? Currently when we enter a long title, it will not add .png at the end of the file when saving the file. So we might wanna trim the file name when saving. (fixed this bug by trimming the title)
• Add option for grid icon layout.
