NUXT: Module not found: Error: Can't resolve 'fs' - node.js

Question

I'm starting out with vue and nuxt, I have a project using vuetify and I'm trying to modify the carousel component to dynamically load images from the static folder. So far I've come up with:
<template>
<v-carousel>
<v-carousel-item v-for="(item,i) in items" :key="i" :src="item.src"></v-carousel-item>
</v-carousel>
</template>
<script>
function getImagePaths() {
var glob = require("glob");
var options = {
cwd: "./static"
};
var fileNames = glob.sync("*", options);
var items = [];
fileNames.forEach(fileName =>
items.push({
'src': '/'+fileName
})
);
return items;
}
export default {
data() {
return {items :getImagePaths()};
}
};
</script>
When I test this I see:
ERROR in ./node_modules/fs.realpath/index.js
Module not found: Error: Can't resolve 'fs' in '....\node_modules\fs.realpath'
ERROR in ./node_modules/fs.realpath/old.js
Module not found: Error: Can't resolve 'fs' in ....\node_modules\fs.realpath'
ERROR in ./node_modules/glob/glob.js
Module not found: Error: Can't resolve 'fs' in '....\node_modules\glob'
ERROR in ./node_modules/glob/sync.js
Module not found: Error: Can't resolve 'fs' in '.....\node_modules\glob'
googling this I see a bunch of references like https://github.com/webpack-contrib/css-loader/issues/447.
These suggest that you have to midify the webpack config file with something like:
node: {
fs: 'empty'
}
I know very little about webpack. I found https://nuxtjs.org/faq/extend-webpack/ , but am not sure how to modify the webpack config file in this case.
How do I do this?

You can't use NodeJs specific module on browser.
To solve your issue, you can create an API using Nuxt server middleware. The code below, inspired by https://github.com/nuxt-community/express-template.
Create a file, index.js in api/index.js. Then fill it with:
const express = require('express')
// Create express instance
const app = express()
// Require API routes
const carousel = require('./routes/carousel')
// Import API Routes
app.use(carousel)
// Export the server middleware
module.exports = {
path: '/api',
handler: app
}
Create carousel.js in api/routes/carousel.js. Then fill it with:
const { Router } = require('express')
const glob = require('glob')
const router = Router()
router.get('/carousel/images', async function (req, res) {
const options = {
cwd: './static'
}
const filenames = glob.sync('*', options)
let items = [];
filenames.forEach(filename =>
items.push({
'src': '/'+filename
})
);
return res.json({ data: items })
})
module.exports = router
Register your server middleware in nuxt.config.js
module.exports = {
build: {
...
},
serverMiddleware: [
'~/api/index.js'
]
}
Call the api in your page / component. I assume you're using Axios here (axios-module).
<script>
export default {
async asyncData ({ $axios }) {
const images = (await $axios.$get('/api/carousel/images')).data
return { images }
}
}
</script>

I know this is an old question, but it may be helpful for someone to disable fs in their browser.
Like this:
nuxt.config.js
build: {
extend (config, { isDev, isClient }) {
config.node= {
fs: 'empty'
}
// ....
}
},

Answer 3

Add this in your nuxt-config.js:
build: { extend (config, { isDev, isClient }) {
config.node = {
fs: 'empty'
}
// ....
}},
