dataOptions
is an object that you can pass configurations to, to tweak the behavior of your particular hook or HOC. It is the 4th param you pass to the hook (either useData
or useLazyData
), or the dataOptions
field of the object you pass to the HOC (withData
or withLazyData
).
dataOptions
Passing - To hook
const { data, error, loading } = useData('http://localhost:3000/some-rest-api/3',{query: 'params',},{method: 'GET',},// This 4th param is the `dataOptions` object{ssr: true,fetchPolicy: 'cache-first',});
- To HOC
const MyComponent = () => {}const MyComponentWithData = withData({url: 'http://localhost:3000/some-rest-api/24',name: 'myData',queryParams: { query: 'params' },fetchOptions: { method: 'GET' },// passed in the `dataOptions` fielddataOptions: {ssr: true,fetchPolicy: 'cache-first',},})(MyComponent);
Configurations
Following is a list of all the fields possible to be configured in the dataOptions
object
ssr
- Type:
boolean
- Default:
true
Determines whether the particular data should be fetched during server side rendering or not. Setting this true
does not affect lazy data.
fetchPolicy
- Type:
'cache-first' | 'cache-and-network' | 'network-only'
- Default:
'cache-first'
Determines the how the data is handled. A more detailed explanation can be found in Caching.
skip
- Type:
boolean
- Default:
false
Determines whether the data should be fetched or not.
raw
- Type:
boolean
- Default:
false
Determines whether to return the data
as raw response string, or JSON. For example, setting this to true
will cause the data
to be a string like {\"message\":\"Hello world!\"}
.
prefetch
- Type:
boolean
- Default:
false
Determines whether the particular data should be prefetched. Usually used with lazy data. This has no effect when ssr
is true
. A more detailed explanation can be found in Prefetching.
