GraphQL as state management
GraphQL is a "data query and manipulation language for APIs"

- Apollo Client 1 & 2: build the best GraphQL Client
- Apollo Client 3: a library for interacting with a client-side data graph
Apollo Client mission
Local state management with GraphQL
GraphQL in 2020
GraphQL as state management
Simple local state example
GraphQL in 2020
GraphQL as state management
import { TypePolicies, makeVar } from '@apollo/client';
export const DARK_MODE_KEY = 'dark-mode'
export const darkMode = makeVar<boolean>(localStorage.getItem(DARK_MODE_KEY) || false)
export const resolvers: TypePolicies = {
Query: {
fields: {
darkMode: {
read: () => darkMode(),
},
},
},
};
export default resolvers
const { data } = useQuery(`
query isDarkMode {
darkMode @client
}
`)Example: darkMode settings
GraphQL in 2020
GraphQL as state management
import { TypePolicies, makeVar } from '@apollo/client';
export const DARK_MODE_KEY = 'dark-mode'
export const darkMode = makeVar<boolean>(localStorage.getItem(DARK_MODE_KEY) || false)
export const resolvers: TypePolicies = {
Query: {
fields: {
darkMode: {
read: () => darkMode(),
},
},
},
};
export default resolvers
darkMode(true)updates
useQuery() hook
Example: darkMode settings
GraphQL in 2020
GraphQL as state management
import { darkMode, DARK_MODE_KEY } from './resolvers'
const useUpdateDarkMode = () => useCallback(
(enabled: boolean) => {
localStorage.setItem(DARK_MODE_KEY, enabled)
darkMode(enabled)
},
[],
)
export default useUpdateDarkMode

More advanced local state example
GraphQL in 2020
GraphQL as state management
- TodoList items are remote (GQL API)
- The newly created Todo is local
- Totally transparent at component- level
const { data, error } = useMainTopicListQuery()
// data contains remote + local todosGraphQL in 2020
GraphQL as state management
Adding the TodoDraft to the list Query
Apollo Cache
TypePolicies read()

useQuery() hooks
GraphQL in 2020
GraphQL as state management
1. Adding the TodoDraft to the list Query
const { data } = useQuery(`
query getMainTopicList($completedAfter: DateTime!) {
activeTopics: topicsList(first: 200, view: ACTIVE) {
hasAfter
items {
...TopicListItem
}
}
}
`)const typePolicies: TypePolicies = {
Query: {
fields: {
topicsList: {
keyArgs: ['view', 'first'],
// ...
read: (existing, { args }) => {
const draft = todoDrafts()
return draft ?
{
...existing,
items: [
draft,
...(existing ? existing.items : []),
],
}:
existing
},
},
},
},
}GraphQL in 2020
GraphQL as state management
2. Todo `isDraft` local property
fragment TodoListItem on Todo {
id
reference
title
# ...
isDraft @client
# ...
}export const resolvers: TypePolicies = {
// we augment the `Todo` type
Todo: {
fields: {
isDraft: {
read: (existing = false, { readField }) => isDraft(readField('id')),
},
},
},

Full local state management capabilities
- State: managed by ApolloCache, along side with APIs data
- Computed values: TypePolicies
- Actions: reactive variables or client.writeQuery()
- Reactions: Apollo ObservableQuery + reactive variables
- Tools: Apollo Client Dev tools

GraphQL Full-stack type safety
Given a GraphQL Schema, generates:
- TypeScript types definition
- React Apollo hooks definition
- urql components
- Types for Flow, Java, Kotlin

GraphQL without queries: gqless
const User = graphql(({ user }: { user: User }) => (
<div>
<h2>{user.name}</h2>
<img src={user.avatarUrl({ size: 100 })} />
</div>
))
const App = graphql(() => (
<div>
{query.users.map(user => (
<User key={user.id} user={user} />
))}
</div>
))query App {
users {
id
name
avatarUrl(size: 100)
}
}+ TypeScript support

Beyond a "Facebook & Apollo technology"
GraphQL in 2020
GraphQL in 2020 ⚡️
- Better front-end developer experience (Full-stack type safety, ...)
- Easier complex GraphQL API building (Hasura)
- Fast GraphQL Database (Dgraph, Hasura)
- GraphQL as a universal data language (state, GraphQL Mesh)
Beyond fetching data from the client-side
GraphQL in 2020
GraphQL: Looking forward
- Subscriptions / Async evolutions
- Apollo 3, Hasura
- @defer, @live
- Smarter client-side cache?
- Better mobile clients ecosystem?
- more public APIs?
GraphQL in 2021?
Thank you!
