How to transfer request body to GraphQL context?

Question

I'm currently trying to get the request body in context because the body part contains a JWT that needs to be decoded. However, when I try to do the following, I get undefined for the context:

app.use('/', graphqlHTTP((req) => ({ schema: Schema, context: req.body, pretty: true, graphiql: false }))); 

I logged out and I did not see the body there. I use a library called react-reach , it adds the following to the request body:

  { query: {...}, queryParams: {...}, options: { token: '...' // <-- I'm passing the token into options } } 

I know that the body is interpreted because my requests / mutations that are in the body are interpreted and executed. It simply cannot find it when it is passed into context.

Your req.body is undefined unless you use an additional binder for the parser body. From the Express documentation:

req.body

Contains key-value data pairs sent to the request body. By default, it is undefined and populates when you use body parsing middleware such as body-parser and multer. http://expressjs.com/en/api.html#req.body

graphqlHTTP does this to check the request body (see here ) and why your requests / mutations work.

Adding middleware (e.g. body-parser or multer) to parse the request body should make it available on req.body , and then your context should be filled with what you are looking for.
