I am working on an app using a React frontend and Express backend, with GraphQL setup through Apollo (I am following and modifying tutorial https://www.youtube.com/playlist?list=PLN3n1USn4xlkdRlq3VZ1sT6SGW0-yajjL)
I am currently attempting deployment, and am doing so with Heroku. Everything functions perfectly on my local machine before deployment and on Heroku in Google Chrome. However, I get the aforementioned errors in Safari and Firefox, respectively. Wondering why this is happening in these browsers and how to fix.
I have spent about 10 hrs doing research on this. Things I tried that made no difference:
- I tried adding CORS to my express backend
- I tried serving the graphql endpoint as HTTPS
- Moving app.use(express.static) in main app.js server file
I couldn't find many other things to try. Everywhere I looked seemed to say that CORS fixed the problem, but mine persists.
Github link: https://github.com/LucaProvencal/thedrumroom Live Heroku App: https://powerful-shore-83650.herokuapp.com/
App.js (express backend):
const cors = require('cors')
// const fs = require('fs')
// const https = require('https')
// const http = require('http')
app.use(express.static(path.join(__dirname, 'client/build')));
app.use(cors('*')); //NEXT TRY app.use(cors('/login')) etc...
app.use(cors('/*'));
app.use(cors('/'));
app.use(cors('/register'));
app.use(cors('/login'));
app.get('/login', (req, res) => {
res.sendFile(path.join(__dirname, "client", "build", "index.html"));
});
app.get('/register', (req, res) => {
res.sendFile(path.join(__dirname, "client", "build", "index.html"));
});
server.applyMiddleware({ app }); // app is from the existing express app. allows apollo server to run on same listen command as app
const portVar = (process.env.PORT || 3001) // portVar cuz idk if it will screw with down low here im tired of dis
models.sequelize.sync(/*{ force: true }*/).then(() => { // syncs sequelize models to postgres, then since async call starts the server after
app.listen({ port: portVar }, () =>
console.log(`π ApolloServer ready at http://localhost:3001${server.graphqlPath}`)
)
app.on('error', onError);
app.on('listening', onListening);
});
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
next();
});
Full file is on Github, I tried to post only relevant parts above.
The expected result is that it works in all browsers. It seems from my research that since Heroku serves on HTTPS, Safari and Firefox do not allow requests to HTTP (which is where the graphql server is located, http://localhost:3001/graphql'). When I tried serving Apollo on HTTPS, Heroku just crashed, giving me H13 and 503 errors.
Thanks for any help...
