Features I wanted as UI developer
- Fast data queries with all&only needed data
- Data caching, to avoid refetching
- Allow to work offline
- Specify queries, parses data
- Easy to paginate
- Execute mutations, with cache and pagination
GraphQL server isn't that easy...
Tips & tricks
- Use limits on bigger amount of data
- Define schema first
- Read carefully full specification, it may help
