return api.request<{ createUser: User }>(mutation, variables).then(r => r.createUser.id)mattbryanswan
12/14/2017, 8:03 PMI'm trying to add an additional mutation into this process, but that return line is tripping me up.

12/14/2017, 8:42 PMHey, I suppose you are not very familiar with TypeScript? simple smile the part inside
<>return api.request(mutation, variables).then(r => r.createUser.id)Promisematic
12/14/2017, 8:43 PMIn order to add another mutation it is probably best to add
.then(anotherPromise)api.request(mutation. variables).then(r => r.createUser.id)api.request(mutation, variables).then(r => r.createUser.id).then(anotherPermission)matic
12/14/2017, 8:45 PMOn the other hand you could also wrap whole functions inside a
try...catch...awaitawaitmatic
12/14/2017, 8:47 PMSomething like this 🙂 :
Copy code
async function createGraphcoolUser(api: GraphQLClient, email: string, password: string): Promise<string> {
const mutation = `
mutation createGraphcoolUser($email: String!, $password: String!) {
createUser(
email: $email,
password: $password
) {
id
}
}
`
const variables = {
email,
password: password,
}
try {
const user = await api.request<{ createUser: User }>(mutation, variables)
.then(r => r.createUser.id)
const res = await api.request(yourMutation, yourVariables)
return res
} catch(err) {
throw err
}
}m
