steemQL 0.6.0 - GraphQL API Wrapper for Steem

steemQL, the Steem GraphQL server, is evolving at the speed of light. This is a major version update due to some breaking changes and final design decisions. It basically wraps most of the standard steem API calls and enables near complete interaction with the blockchain. To separate these queries/mutations from custom convenient calls they are prefixed with _ (underscore).

The next steps are to implement custom, opinionated convenience queries to enable the full strength of GraphQL: Nesting of related data (Graphs, hence the name). This allows fetching data e.g. for an user (author) along with his last posts in one query. No need for 2 or more queries to build a simple user profile view. And it can reduce the used bandwidth, esp. for mobile, as only needed return values can be specified, unlike with the common API libs like steemjs which fetches all properties (~40) e.g. for discussions. This will be explained in more detail in one of the next updates.

New Features

• Most of the standard steem API calls wrapped in queries/mutations
• Standard calls prefixed with _ for better separation from custom queries

The standard queries leave it to the developer do deal with special formatting of specific return values and input params, e.g. parsing json_metadata and provide the right format for updates/inserts.
This will become easier with custom queries which will take care of any kind of formatting and enable the simplest queries/mutations possible like createPost(author, title, body, tags) and steemql will take care of creating permlink, json_metadata and so on.. no messing with dozens of input params.

Roadmap

• Custom convenience method for easier querying and minimal number of params
• Subscriptions for post/comment related queries, to use with GraphQL Clients like Apollo
