I'm trying to load the fs module to create a webpage with CSS, but I can't install the module.
I receive the error:

Uncaught Error: Module fs not found
at line 2 col 22
var fs = require('fs');

@Zyrotot, was this post as a follow up to a suggestion I made in this post?

Retrieving a file from my Espruino board to my computer

Is the SD Card installed and accessible?

This should provide some insight:

[SOLVED] Is there anyway to have a filesystem-like facility on ESP8266?

What version is currently flashed? process.env

Well, fs is too much for the ESP8266.

• Use the Storage module to save pages and css (store_webdata.js)
• Load them in your app (in_your_app.js).

store_webdata.js

require("Storage").write("mypage", `
   your page data
`);
require("Storage").write("mycss", `
   your css data
`);

in_your_app.js

mypage = require('Storage').read('mypage');
mycss =  require('Storage').read('mycss');

On ESP8266 Storage is located in the memory mapped section, using this technic is fast and saves vars and heap.
