Configuration

Glasnost now requires a PostgreSQL database.

You need to configure the following Postgres database parameters using the Docker ENV variables:

• GLASNOST_DB
• GLASNOST_DB_HOST
• GLASNOST_DB_PORT
• GLASNOST_DB_USERNAME
• GLASNOST_DB_PASSWORD

Other parameters, such as PORT, STEEM_URL and GOLOS_URL, can be configured in the Docker file.

Changelog

• added GraphQL query for block data with height or getLast: true arguments
• added GraphQL query for basic statistics
• added order_by (created,total_payout_value и pending_payout_value) and sort(asc, desc) arguments for comments query with possible values suggested in GraphiQL interface
• new queries examples
• minor bugfixes
• docker image update

Examples of GraphQL queries

{
  comments(blockchain:"steem", author: "ontofractal", isPost: true, category: "steemdev", orderBy: TOTAL_PAYOUT_VALUE, sort: DESC){

    title,
    author,
    permlink,
    parentAuthor,
    parentPermlink,
    body
    tags,
    category,
    created,
    totalPayoutValue,
    pendingPayoutValue
  }
}

{
  comment(blockchain:"steem", author: "ontofractal", permlink: "glasnost-v0-12-released-now-with-postgresql-realtime-and-7-day-lookback-comments-data-sync-open-source-app-server-for-steem"){
    id,
