Self serializers
A self-serializer is a React component that leverages the useSerialized()
hook from @shopify/react-html
to handle both serializing data during server rendering, and deserializing it on the client. The components often render React.context()
providers to make their serialized state available to the rest of the app they're rendered in.
Comparison with traditional serialization techniques
Consider the I18n
self-serializer. In the server you may want to set the locale based on the Accept-Language
header. The client needs to be informed of this somehow to make sure React can render consistently. Traditionally you might do something like:
On the server
- get the locale from the
Accept-Language
header in your node server - create an instance of
I18nManager
with that locale - pass the instance into your app
- render a
<Serialize name="locale" />
component in the DOM you send to the client
On the client
- call
getSerialized('locale')
in your client entrypoint for your locale - create an instance of
I18nManager
with that locale - pass the instance into your app
In your react app's universal code
- have your app render an
<I18nProvider />
with the manager from props
With self-serializers you would instead:
On the server
- get the locale from the
Accept-Language
header in your node server - pass the locale into your app directly
On the client
- render your app without passing in the locale
In your react app's universal code
- have your app render an
<I18n />
with the locale from props
Since self-serializers handle the details of serialization they allow you to remove code from your client/server entrypoints and instead let the react app itself handle those concerns.
API
I18n
A self-serializing provider for @shopify/i18n
's I18nManager.
Props
The component takes an object containing the React children to render and any options to use when configuring the I18nManager
to provide to the tree.
interface Props {
locale?: string;
country?: string;
currency?: string;
timezone?: string;
pseudolocalize?: boolean;
fallbackLocale?: string;
onError?: ((error: I18nError) => void);
children?: React.ReactNode;
}
Example
// App.tsx
import {I18n} from '@shopify/react-self-serializers/I18n';
function App({locale}: {locale?: string}) {
return <I18n locale={locale}>{/* rest of the app */}</I18n>;
}
GraphQL
A self-serializing provider for initial GraphQL data from Apollo.
Props
The component takes children and a function that can create an Apollo client. This function will be called when needed, and the resulting Apollo client will be augmented with the serialized initial data.
Example
interface Props {
children?: React.ReactNode;
createClient(): ApolloClient<any>;
}
// App.tsx
import {ApolloClient} from 'apollo-client';
import {InMemoryCache} from 'apollo-inmemory-cache';
import {createHttpLink} from 'apollo-link-http';
import {GraphQL} from '@shopify/react-self-serializers/GraphQL';
function App({
server,
shop,
accessToken,
}: {
server?: boolean;
shop?: string;
accessToken?: string;
}) {
const createClient = () => {
const link = createHttpLink({
uri: `https://${shop}/admin/api/graphql`,
headers: {'X-Shopify-Access-Token': accessToken},
});
return new ApolloClient({
link,
cache: new InMemoryCache(),
ssrMode: server,
ssrForceFetchDelay: 100,
connectToDevTools: !server,
});
};
return <GraphQL createClient={}>{/* rest of the app */}</GraphQL>;
}
createSelfSerializer
This factor function will create a Self Serialized Provider given a React Context object. It is particularly useful for simple object that need to be sync up between the server and client.
Options
The function takes a unique id and a React Context object.
Props
The resulting Provider takes children and a data prop.
Example
interface Props {
data?: Data;
children?: React.ReactNode;
}
//ApiKeyProvider.tsx
import {createContext} from 'react';
import {createSelfSerializer} from '@shopify/react-self-serializers/create-self-serializer';
export const ApiKeyContext = createContext<string | null>(null);
export const ApiKeyProvider = createSelfSerializer('api-key', ApiKeyContext);
// App.tsx
import {ApiKeyProvider} from './ApiKeyProvider';
function App({apiKey}: {apiKey?: string}) {
return <ApiKeyProvider data={apiKey}>{/* rest of the app */}</ApiKeyProvider>;
}
AppBridge
A self-serializing provider for @shopify/app-bridge-react
's Provider.
Props
The component takes children, apiKey
, shop
, and forceRedirect
. Similar to @shopify/app-bridge-react
's Provider.
interface Props {
apiKey?: string;
shop?: string;
forceRedirect?: boolean;
children?: React.ReactNode;
}
Example
// App.tsx
import {AppBridge} from '@shopify/react-self-serializers/AppBridge';
function App({apiKey, shop}: {apiKey?: string; shop?: string}) {
return <AppBridge config={{apiKey, shop}}>{/* rest of the app */}</AppBridge>;
}
