The documentation contains more information on how to set up some of these
confguration options. More documentation is in progress.
> Note that you don't need any of these options to get started
- [Getting Started guide](./docs/getting-started.md)
- [Architecture information](./docs/architecture.md)
### Keys
## API
Keys are used when you need a slight alteration to the value of your identifier or
when the identifier is a non-traditional property.
The `cacheExchange` accepts an object with three optional configuration items.
[Read more](./docs/keys.md)
```typescript
{
keys?: KeyingConfig;
resolvers?: ResolverConfig;
updates?: UpdatesConfig;
optimistic?: OptimisticMutationConfig;
}
```
### Resolvers
Resolvers are needed when you want to do additional resolving, for example do some
custom date formatting.
[Read more](./docs/resolvers.md)
### Updates
The graph cache will automatically handle updates but some things are quite hard to
incorporate. Let's say you delete/add an item, it's hard for us to know you wanted to
delete or where to add an item in a list.
[Read more](./docs/updates.md)
### Optimistic
Here you can configure optimistic responses, this means that we don't wait for the server
to respond but offer the user to instantly replace the data with the variables from the
mutation.
[Read more](./docs/optimistic.md)
## Maintenance Status
**Active:** Formidable is actively working on this project, and we expect to continue for work for the foreseeable future. Bug reports, feature requests and pull requests are welcome.
