Using Bootstrap

While you can use Bootstrap directly, there are many advantages in using a library such as Reactstrap to provide ready-made React components, instead of having to reference bootstrap classes manually.


Make sure you are in the web folder before running the commands below:

cd ./web


Install dependencies from NPM:

npm install --save bootstrap reactstrap

Then load the Boostrap CSS from src/index.js:

import 'bootstrap/dist/css/bootstrap.min.css';


Refer to Reactstrap documentation for more information.

Advanced: customize bootstrap

Bootstrap can be customized by loading the SCSS files instead, and providing custom configuration variables.

This allows tweaking things like colors, sizes, etc.

To keep things organized, we’ll start creating a style folder:

mkdir src/style

Create a src/style/_vars.scss file, to load all the customized variables

@import "~bootstrap/scss/functions";
@import "./custom";
@import "~bootstrap/scss/variables";


The main advantage of having this as a separate file, rather than in is we can then load variables from this file into any of our other scss files.

Then, copy the bootstrap variables to _custom.scss:

cp ./node_modules/bootstrap/scss/_variables.scss ./src/style/_custom.scss


While just adding overridden variables to _custom.scss would be enough, we find it makes life a lot easier to be able to search for variables / tweak them directly in one file.

Keep in mind you can remove the !default marker from variables as you customize their values.

You can then create a src/style/index.scss to load all the bootstrap SCSS, along with the required customizations:

@import "./vars";
@import "~bootstrap/scss/bootstrap";


You can load individual components instead of the whole bootstrap.scss.

This has the benefit of reducing bundle size (and compile time).

Have a look at node_modules/bootstrap/scss/bootstrap.scss to see which imports you’re going to need.

Finally, load it from src/

@import "~style/index";
