Alternative Answer: CSS Preprocessing
I'm posting a somewhat indirect way to answer the question. I came here looking to see how I could use rendered SASS in my main app.js
(in my case, for use in a pug.js template).
The answer is: use a CSS pre-processor. In this minimal example, I'll use node-sass.
0. Install:
npm install node-sass
npm install bulma
1. Create an inherited style
mystyles.scss
:
@charset "utf-8";
@import "node_modules/bulma/bulma.sass"; // <--- Check and make sure this file is here after installing Bulma
This will inherit styles from the Bulma installation, but override those styles with what you place here.
2. Build the CSS
app.js
:
const nsass = require("node-sass");
const rendered_style = nsass.renderSync({ // <---- This call is synchronous!
file: "./mystyles.scss",
});
Here, node-sass is processing the .scss
file into a Result object that has CSS buffer. Note that node-sass
has an asynchronous call (sass.render()
) as well, if needed.
3. Use the CSS
The buffer containing the CSS is now available at rendered_style.css
console.write(rendered_style.css)
--Notes--
The benefit of the SASS approach is that it unlocks Customization, which is what makes Bulma powerful!
Keep in mind that if app.js
is your entry point, the CSS will be rendered every time you run the server. If your styles aren't changing frequently, it may be best to write it out to a file. You can see more on this approach in the Bulma Documenation I adapted this from.
import Bulma from 'bulma'
in main.js and it works. – Ctenidium
