We'll use Gulp to create a REACT project.
For that we will use gulp-babel, gulp-sourcemaps, and gulp-concat

We have created a project and we want to add gulp to the project. To that end we need to do the following:

npm i -g gulp-cli
mkdir gulpexample
cd gulpexample
npm init -y
npm i -save-dev gulp

Next create file called gulpfile.js

touch gulpfile.js

Creating Gulp tasks involve writing Node code with Gulp's API in a file called gulpfile.js. Gulp's API has methods for things like finding files and piping them through plugins that change them.

We are going to do the following to illustrate how to create a gulp task

• We use gulp.src to find JSX file
• use Babel to process ES2015 and React
• concat and join each file together

As projects grows, they tend to need more tasks. We end up with long gulpfile that is difficult to understand. We can get around this problem by breaking the gulpfile code into separate modules.
Gulp uses Node's module system to load its plugins. So we can use Node's module system to split long gulpfile to make them more maintainable. To use separate files, we do the following:

1. Create a folder called gulp and a sub-folder called tasks

mkdir -p gulp/tasks

2. Inside the tasks folder create gulp build file

cd gulp/tasks
touch development-build.js production-build.js

3. Inside ./gulp folder, create a file called index.js

cd .. to cd to the gulp folder and touch index.jsto create the index.js file

As a web developer we want to avoid build/refresh cycle as possible. One simple way to streamline builds is to use a Gulp plugin to watch the filesystem for changes.
