### Mutations

#### Schema

Here we have one `User`'s type with three fields (email, fullname and password), one `Query` type with a profile field just to keep GraphQL's mouth shut about having a Query type defined. We have two `Mutation` types (login, and signup).

```ts
type User {
email: String
fullname: String
password: String
}

type Query {
profile: User
}

type Mutation {
createUser(email: String!, fullname: String, password: String!): User
login(email: String!, password: String!): User
}
```

#### Resolvers

The resolvers we care about here are `createUser` and `login`. They both take in `email` and `password` as arguments with `createUser` taking an extra `fullname` argument.

```js
Mutation: {
createUser(root, { email, fullname, password }, { login }) {
const user = new User({ email, fullname })

return new Promise((resolve, reject) => {
return User.register(user, password, err => {
if (err) {
reject(err)
} else {
login(user, () => resolve(user))
}
})
})
},
login(root, { email, password }, { login }) {
return new Promise((resolve, reject) => {
return User.authenticate()(email, password, (err, user) => {
// user returns false if username / email incorrect
if (user) {
login(user, () => resolve(user))
} else {
reject('Email / Password Incorrect')
}
})
})
}
}
```

### Models

Oops! We have only one model (User). It accepts email, validates the email with `express-validator`. Then we have a plugin to tell `passport-local-mongoose` to use our email field as the default `usernameField`.

```js
const userSchema = new Schema({
email: {
type: String,
unique: true,
lowercase: true,
trim: true,
validate: {
isAsync: true,
validator: (v, cb) =>
cb(validator.isEmail(v), `${v} is not a valid email address`)
},
required: 'Please Supply an email address'
},
fullname: String
})

userSchema.plugin(passportLocalMongoose, {
usernameField: 'email',
errorMessages: {
UserExistsError: 'Email Already Exists'
}
})
```
