Running flutter web app locally without android studio - flutter

Question

I have a flutter app using Firebase's cloud firestore. I've done the web build and running it on Chrome through Android Studio works well. I would like to share my web app progress to my client but don't want to host it (because it's not finished yet). Hence I'd like to find a way to run it locally the same way you can do it with Android Studio but without needing to install Android Studio (and hopefully not requiring to install flutter either), so that I can send the build file to my client and they can run it in their machine (with a script to start the web server locally and run the web app).
I have tried the following script included inside the web build folder (where the index.html is)
from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer
from httplib import HTTPResponse
from os import curdir,sep
#Create a index.html aside the code
#Run: python server.py
#After run, try http://localhost:8080/
class RequestHandler(BaseHTTPRequestHandler):
def do_GET(self):
if self.path == '/':
self.path = '/index.html'
try:
sendReply = False
if self.path.endswith(".html"):
mimeType = 'text/html'
sendReply = True
if sendReply == True:
f = open(curdir + sep + self.path)
self.send_response(200)
self.send_header('Content-type', mimeType)
self.end_headers()
self.wfile.write(f.read())
f.close()
return
except IOError:
self.send_error(404,'File not found!')
def run():
print('http server is starting...')
#by default http server port is 80
server_address = ('127.0.0.1', 8080)
httpd = HTTPServer(server_address, RequestHandler)
try:
print 'http server is running...'
httpd.serve_forever()
except KeyboardInterrupt:
httpd.socket.close()
if __name__ == '__main__':
run()
But when opening http://localhost:8000 on Chrome I get a blanc page and the console shows the errors:
Failed to load resource: net::ERR_EMPTY_RESPONSE main.dart.js:1
Failed to load resource: net::ERR_EMPTY_RESPONSE manifest.json:1
Failed to load resource: net::ERR_EMPTY_RESPONSE :8080/favicon.png:1
I also tried NPM local-web-server by running ws --spa index.html but just getting a ERR_EMPTY_RESPONSE response.
This is what I have in my build/web after running flutter build web:
How can I create a local server where I can host my web app locally and run it locally without hosting it on the internet?

Answer 1

as you mentioned in the comment here you go.
Create a file app.js with the following:
const express = require('express')
const app = express()
const port = 8000
app.get('/', (req, res) => {
console.log('getting request')
res.sendFile('website/y.html',{root:__dirname})
})
app.use(express.static(__dirname + '/website'))
app.use((req, res)=>{
res.redirect('/')
})
app.listen(port, () => {
console.log(`app listening at http://localhost:${port}`)
})
Here my website files exist at website folder and my entry point is y.html.
Set the static file directory (your website page) and then serve the .html for the root request
example project: https://github.com/ondbyte/website
Finally, to run it open terminal and move to the root folder. Then do
npm init
npm install express --no-save
node app.js

Here is the more simpler way. NO NEED to setup server
open your Build/web folder in vscode.
install Live server Plugin in vscode.
hit Golive Button
Here you go your flutter web app would be running locally without android studio.
