Post data to a graphql server with request-promise - graphql

Question

I'm using the request-promise library to make http request to a graphql server. To achieve a query, I'm doing this:
const query = `
{
user(id:"123173361311") {
_id
name
email
}
}
`
const options = {
uri: "http://localhost:5000/graphql",
qs: { query },
json: true
}
return await request(options)
The above code is working fine. However I'm confused about how to go about a mutation since I need to specify both the actual mutation and the inputData like this:
// Input
{
name: "lomse"
email: "lomse#lomse.com"
}
const mutation = `
mutation addUser($input: AddUserInput!){
addUser(input: $input) {
_id
name
email
}
}
`
const option = {
uri: "http://localhost:5000/graphql",
formData: {mutation},
json: true,
// how to pass the actual data input
}
request.post(option)
Or is it that the request-promise library isn't designed for this use case?

Answer 1

Use body, not formData. Your body should consist of three properties:
query: The GraphQL document you're sending. Even if the operation is a mutation, the property is still named query.
variables: A map of your variable values serialized as a JSON object. Only required if your operation utilized variables.
operationName: Specifies which operation to execute. Only required if your document included multiple operations.
request.post({
uri : '...',
json: true,
body: {
query: 'mutation { ... }',
variables: {
input: {
name: '...',
email: '...',
},
},
},
})

Answer 2

The graphql-request library seems to do what I needed the request-promise library to do.
import { request } from 'graphql-request'
const variables = {
name: "lomse",
email: "lomse#lomse.com"
}
const mutation = `
mutation addUser($input: AddUserInput!){
addUser(input: $input) {
_id
name
email
}
}
`
response = await request(uri, mutation, {input: variables})
