Change the world, one line of code at a time
People like to look at changing the world as a big task. I believe changing the world can be done in little steps.
The key is identifying a problem and taking a little step.
My journey began on Friday, September 7th, 2018. That was the day I decided to build a React plugin for the freeCodeCamp Test Suite. I noticed a problem and I took action.
There is a working version up for installation on the Node Package Manager registry. This is a milestone for me, as the project is my first Open Source contribution.
I used certain key technologies to build the project, like Webpack, React, NPM, and Node.js. I had a lot of fun building it, and I learned a lot, too.
I tried several times (for a whole day actually) before I could even succeed in making the plugin work.
After making it work, implementation in a React app was a challenge. Although I was faced with technical difficulties, in the end, the plugin worked.
The idea behind the project was simple. All I wanted to do was find a simple way to add the freeCodeCamp Test Suite to React apps.
My first plan was to build it with Create-React-App.
I felt that since I could use it to build React applications, I could use it to build a plugin. I was wrong.
Create-React-App was too heavy for what I needed to build.
I discovered that to make the plugin easy to export, I would need some extra configuration.
I went online and googled a couple of times, and came across Webpack and react-helmet. What I came across was both amazing and confusing, at first.
Still, I knew they were what I needed. I continued searching some more.
Before Webpack, I had tried exporting and publishing the plugin as a module with no extra configuration. It did not work. Newbie mistake, I know.
This was a big challenge that I had to overcome.
Thankfully, we learn as we grow!
While I was developing the plugin, there were constant power cuts. In Nigeria, the power situation is not very settled.
I had to work until my laptop powered out, then think deeply about what to do when power returned.
All of this happened on the second day (Saturday).
The magic, the beauty
Using Webpack, I began building the plugin.
I placed the core code in an index.js file. Here is the code below:
The code above was all I needed to add the script to the head tag of any React app I desired.
I came across an article on Medium which was a great help to me.
It helped me understand how to use Webpack to create a node module that I could successfully publish to the Node Package Manager registry.
I followed the instructions in that article. After making some changes, I built the following webpack.config.js file:
Let me explain what this file is doing:
>> First, it is using the HtmlWebpackPlugin to create an HTML file to serve my webpack bundle.
>> Next it is exporting the plugin I created as a node module.
>> It is saying that the entry point of my plugin is in the loc
ation demo/src/index.js. This means that this is where the code to be exported will be taken from.
>> Next, it is saying that the output directory of my plug
in is demo/dist . In this directory, the react-fcctest plugin will be exported in a file
>> Next it introduces a set of rules for the file that is to be exported.
>> The rules, tell the file to do two things. One, use babel-loader when working
s and .jsx files and do not includ
e the node_modules folder. Two, use style-loader and css-loader when working
with .css files.
>> The resolve and extensions part of the file allowed me to leave of
f the .j
s and .jsx from the end of my files while importing them.
>> Lastly, my development server was on port 3001. This port could have been any other of my choosing.
I just noticed that beauty involves hard work…
I added Webpack to the project on Sunday, and then the plugin worked!
With this, I was able to create a module that could be easily exported. This module was ReactFCCtest.
I cannot say how much the read-search-ask methodology helped me throughout the project.
Here is Demo of the finished plugin. It was very fun to build.
I tested it out in a freeCodeCamp project, and it worked perfectly.
I created a Github Repository that holds all the open source code for the project.
How to install and use `react-fcctest`
npm i react-fcctest or
yarn add react-fcctest to install the React plugin.
import ReactFCCtest from 'react-fcctest'; in your App.js:
That is all there is to it!
My 2018 so far has been amazing.
I am now the Developer Student Club Lead for my university, in a program powered by Google Developers in Sub-Saharan Africa.
I am aiming for greatness, in outer space — perhaps I might just land on a moon. Follow me on my journey.
