I have wrote a cusom express middleware to pars an incoming multipart form.
The middleware works fine when launched in local or deployed but the test with jest fails with the error
TypeError: Cannot set property domain of [object process] which has only a getter
The issues seems to come from the package asap used by formidable.
I think that Jest is putting some limitations on the process object since the line where everything breaks is
domain.active = process.domain = null;
in the file raw.js
Does anyone has any workaround or solution for this issue? I cannot migrate to formidable V3 at the moment so that's not an option
I have an API key hidden in a file, I'm not using dotenv to do this, and I'm importing them into my javascript file via ES6 modules. Netlify allows build commands to build this when the app is deployed.
cd scripts && echo -e "const API_KEY = 'blahblahblah'; const HASH_KEY = 'blahblahblah'; const TIME_STAMP = 'ts=1'; const URL_ENDPOINT='blahblahblah';\n\nexport API_KEY, HASH_KEY, TIME_STAMP, URL_ENDPOINT;" > apikey.js
That is what I put into Netlify's deploy settings.
When I go to the deployed site, I get "Uncaught syntax error: unexpected token export".
The file is made correctly in the sources tab of the console. I'm at a loss for what I've done incorrectly, or what Netlify isn't interpreting correctly.
I found the solution:
I was missing brackets in the build command, and after that I had to update some links from HTTP: to HTTPS:.
Thanks for trying to help out.
Has anyone used axios-cookiejar-support with Vue.js on the backend?
I'm getting the following error in the Chrome debugger:
Uncaught (in promise) TypeError: axiosCookieJarSupport is not a function
And when I console.log(axiosCookieJarSupport) I see "undefined" when I run the the init code shown on the axios-cookiejar-support site that modifies Axios to support cookies:
const axiosCookieJarSupport = require('axios-cookiejar-support').default;
axiosCookieJarSupport(axios); // <--- error occurs here
Obviously, I tried it with a Node.js console application and it works, and I can console.log axiosCookieJarSupport and I see that it is a function in the console application.
I'm guessing I need to somehow tell Webpack (which I believe Vue.js uses) to preload axios-cookiejar-support, as opposed to just include it in the package.json (which I did), but I'm not sure how to do it.
I created nodeJS server that uses levelDOWN module. So when I'm starting my server with node app.js everything is fine. I want to create electron desktop app that will use my app.js file. So I installed electron module and created electronApp.js file:
var app = require('electron').app;
app.on('ready', function(){
// start http server
var server = require(__dirname + "/app");
});
Now I'm trying to run my application electron electronApp.js but I'm getting next error:
I tried node-gyp rebuild and electron-rebuild as well but it did not help. I'm dissapointed. How to solve it?
I met the same error and submitted an issue on Electron issue list: https://github.com/electron/electron/issues/8161
Hope this can be resolved soon.
I am writing an application for Android 2.3.5 (that will also be compatible with iOS). I wish to transfer data from the app's HTML/Javascript to a Python program on a server (which uses the Twisted engine to retrieve the data).
I've tried many things and looked at various forums, answers, tutorials, and web pages--including most of them here--and can't find an answer. Here's the relevant Javascript I have in my index.html file:
<script src="socket-lib/socket.io.js"></script>
<script type="text/javascript" charset="utf-8">
function sendData() {
try {
var socket = io.connect('http://mywebsite.com:12345');
socket.on('connect', function(data) {
socket.send('Hello.');
socket.on('message', function (msg) {
socket.send('This is where I send data?');
});
});
}
catch(err) {
alert('ERROR: socket.io encountered a problem:\n\n' + err);
}
} // end of sendData
If you can't tell, I'm still pretty confused how this works; I can't even test anything. The error that keeps coming up is ReferenceError: io is not defined. Some sites used something like var io = require('socket.io');. But then it results in the same error: ReferenceError: require is not defined.
I put the socket-lib folder in assets/www, where any other Javascript source should go. This is also where the index.html file is. Many sites use <script src="/socket.io/socket.io.js"></script>, but this makes no sense to me. Many sites also imply the use of node.js, but I never see it anywhere.
How can I make this work?

I tried it in Chrome, and it's giving me an Uncaught ReferenceError: require is not defined for the socket.io.js file. So I decide to source in require.js right before it. Then it gives the error Uncaught Error: Module name "socket.io-client" has not been loaded yet for context. Since I'm not using this, I care not. When I try the connection, though, it gives the same io is not defined error. When I define it as var io = require('socket.io'), the error is Error: Module name "socket.io" has not been loaded yet for context: _ http://requirejs.org/docs/errors.html#notloaded. I looked at the website, and it doesn't help me at all. When I try to put "require" as a function argument, another error occurs: TypeError: undefined is not a function.
I found the answer for anyone who gets immensely confused by the horrible lack of documentation of socket.io.
You cannot source /socket-lib/socket.io.js,
you must source http://yourwebsite.com:12345/socket.io/socket.io.js.
The server automatically does the rest for you.
I solved it myself by changing index.html to import the socket io client from bower, first i installed the bower component:
bower install socket.io-client
then i changed the reference in index.html to :
<script src="bower_components/socket.io-client/socket.io.js"></script>
Or file could be found at - lib/socket.io-client/dist/socket.io.js
I managed to blunder through this, and squandered about an hour, on something that turned out to be a very basic error.
When an function is not defined? Such as " Uncaught ReferenceError: io is not defined ". Does that not mean that the function is getting "used" before it is "created"?
In the part of my HTML file, that "calls" the javaScript files, it looked like this :
<script src='./js/playerChatter.js'></script> <!-- this one calls io -->
<script src="http://localhost:2019/socket.io/socket.io.js"></script><!-- This Creates io -->
and i changed it to this
<script src="http://localhost:2019/socket.io/socket.io.js"></script> <!-- This Creates io -->
<script src='./js/playerChatter.js'></script> <!-- this on calls io -->
So now the item "io", whether it is an object or function... Is actually getting created before it is getting used :D
Have FUN!
write server side code in socket.io.js file and try src="/socket.io/socket.io.js"
hope this will solve your problem
When getting socket.io to work with many other libraries using require.js I had same error, it turned out to be caused because of trying to load the socket.io.js file from the same /js folder than the rest of the other files.
Placing it in a separated folder, fixed it for me, you can see the code in this gist but all I changed for making it work, was this:
instead of:
socketio: 'socket.io',
Use:
socketio: '../socket.io/socket.io',
Not sure about the reason of this behavior, but I hope it helps you.
This looks like your browser cannot find the socket.io.js file. You could try opening the index.html on your computer with Firefox+Firebug or the Chrome Web Developer Tools and look at how the .js file is requested. On the other side, you could check the logs on the webserver serving the .js file whether there are any file not found errors.
The require function would be provided by e.g. RequireJS, but you would still need to configure the paths to your scripts correctly for it to work.
For me after debugging through all of the very helpful suggestions, it turned out to be simply that my node server had stopped. I had been running it manually in a terminal window during dev.
Make sure your node [yourservercode].js is running on the specified port! :-]
I use jspm.
Add this:
import 'btford/angular-socket-io/mock/socket-io';
In my case, using Unity WebGL with C# UnitySocketIO plugin, I need to add delay (1 sec) between Init and Connect, because the first method did not have time to add a new JS Socket object and code (listeners) to the page to work with it..
As mentioned in other answers, you have to use the complete URL.
<script src="http://127.0.0.1:5565/socket.io/socket.io.js "></script>
if it's giving you an error 404 please check whether io is properly instantiated on your server.js.If not please refer following to instantiate the io properly.
<script>
var socket = io();
</script>
In your server.js
const app = express();
const http = require('http'); //from express module
const server = http.createServer(app);
const { Server } = require("socket.io");
const io = new Server(server);
got to url /socket.io/socket.io.js and check if a js file is served or not if yes then instead of writing
var socket = io();
write
window.onload= function(){
var socket = io();
}
