How to use getInitialProps to get cookies?

I’m facing an issue with next.js

I cannot get my cookies when i make a request from async static getInitialProps. i get undefined

However when i am making it in componentWillMount there is no problem. Unfortunately, it’s too late because i need to get the cookie info before the component be called. So i need to get it in getInitialProps

Here what i’ve already tried without success :

static async getInitialProps () { const res = await axios.get('http://mybackend/getCookie'); return {data : res.data} } //res.data = undefined

the purpose is to check the user authentication status in firebase in order to render the appropriate page

Any suggestion ? thanks

I could finally solve this issue. the problem was inside the getinitialprops rather than making req.cookies, i had to do req.headers.cookie and all are working just as expected. Thanks for help.

you can use cookie-parser package. Use it in server.js as follows:

app.prepare().then(() => {
  const server = express();
  server.use(cookieParser());
});

index.js

  static async getInitialProps(context) {
    const { store, isServer, query, req } = context;
    if (isServer) {
      if (isServer) {
         console.log(req.cookies);
      }
    }
    return { isServer };
  }
