Apollo Queries With TTL
This project provides an implementation of Apollo Hook Queries (useQuery and useLazyQuery) with a TTL (Time To Live) for cache hits.
These hooks are useful when you want to control how long your queries can fetch data from cache. In another words, you can provide a TTL in miliseconds to the hook,
it will use the cache-first
fetch policy until the TTL time expires, the next fetch after expiration will use a network-only
policy, then, the TTL will be applied again.
Check Apollo Client docs about fetch policy, here
Instalattion
$ npm i @profusion/apollo-query-ttl
$ yarn add @profusion/apollo-query-ttl
Hooks
This lib exports two hooks:
useQueryWithTTL
: wraps Apollo's useQuery hook with TTL logic
Usage:
const QUERY = gql`
query ContinentsQuery {
data {
id
payload
}
}
`;
const TryQueryTTL = (): JSX.Element => {
const { data } = useQueryWithTTL({
query,
queryOptions: {}, // you can provide all the options available on useQuery
ttl: 10000, // it will allow cache hits for 10 seconds
});
return (
<pre>
{JSON.stringify(data)}
</pre>
)
}
useLazyQueryWithTTL
: wraps Apollo's useLazyQuery hook with TTL logic
Usage:
const QUERY = gql`
query ContinentsQuery {
data {
id
payload
}
}
`;
const TryQueryTTL = (): JSX.Element => {
const [fetch, { data }] = useLazyQueryWithTTL({
query,
queryOptions: {}, // you can provide all the options available on useQuery
ttl: 10000, // it will allow cache hits for 10 seconds
});
return (
<div>
<pre>
{JSON.stringify(data)}
</pre>
<button onClick={fetch}>Fetch!</button>
</div>
)
}
Typing the data
You can type your data
and variables in the same way you do on default queries:
interface DataType {}
interface VariablesType {}
const { data } = useQueryWithTTL<DataType, VariablesType>({
query,
queryOptions: {
variables: {},
},
ttl: 10000,
});
// data and queryOptions.variables will be
// typed as DataType and VariablesType, respectivelly
