Yeah even I am getting the same error. Tried working with the requestHTTP2 and responseHTTP2 methods, but failed. Needs help.

Same.

NodeJS version 11.0.0+ has a core http2 module (previously hidden behind --expose-http2 command-line option).
Using require('http2') will use that core module instead of molnarg's node-http2 module (which is now deprecated).

You may need to require the old http2 module via a relative or fixed path instead then pass it to express-http2-workaround.
I need to update this to check if the core module is passed in or not, to have a more relevant error message be thrown. I'll update the README to mention this information too when I can.

[talwaserman]

can you please provide code snippet of the solution?
is there also a way to use this workaround with the new http2 module ?

[SangeetaKhan]

Any update on this ?

[SangeetaKhan]

@Jashepp Please share me any code for the same

Stumbled upon this thread as I googled for this specific error.
I had an old project that hadn't been updated since 2017 and while running it with node 10 I got the error. (It did work fine on older versions like version 7 though)

As Jasheep said the issue is that node (since version 10 LTS) now has a native http2 so require("http2") will load that one. instead of https://www.npmjs.com/package/http2

The solution is to replace require("http2"); with require("./node_modules/http2"); and all the code examples from the readme will work fine.

@Jashepp - I know this project hasn't been updated in a long time but a suggestion be to update the code in the README with this small change.

---

So @SangeetaKhan , @talwaserman - the code sample from https://github.com/Jashepp/express-http2-workaround#example works if you just change the path for the http2 import.

Here's a full example I used, works fine in node 10.16.3.

var express = require('express');
var http2 = require("./node_modules/http2"); //here's the significant change! this loads the module from https://www.npmjs.com/package/http2 instead of node's built-in
var fs = require("fs");
var app = express();

// Make HTTP2 work with Express (this must be before any other middleware)
require('express-http2-workaround')({ express:express, http2:http2, app:app });

// Setup HTTP/2 Server
var httpsOptions = {
    'key' : fs.readFileSync(__dirname + '/keys/ssl.key'),
    'cert' : fs.readFileSync(__dirname + '/keys/ssl.crt'),
    'ca' : fs.readFileSync(__dirname + '/keys/ssl.crt')
};
var http2Server = http2.createServer(httpsOptions,app);
var port = 5000;
http2Server.listen(port,function(){
  console.log("Express HTTP/2 server started on", port);
});

// Serve some content
app.get('/', function(req,res){
    res.send('Hello World!');
});

Browse to https://localhost:5000 to view the output.

PS: the original example uses 443 but some machines have permission denied for those ports so I changed it to a random one like 5000.
DS: make sure you use https and not http as this example only sets up the https-variant.
