Glasnost transformation into a GraphQL API server is now complete, access to Steem/Golos blockchain data is now possible using GraphQL queries.

# Repos

### [Glasnost Docker hub](https://hub.docker.com/r/ontofractal/glasnost)
### [Glasnost Github Repo](https://github.com/cyberpunk-ventures/glasnost)


# 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 an extractor for the Postgres database, which synchronizes new posts and comments in real time and looks back for comments over last 7 days
* Added a `/graphql` GraphQL API endpoint with `comments` and `comment` objects (see examples below)
* Added an interactive browser-based GraphiQL client at `/graphiql` route
* Previous admin and static HTML pages were completely removed
* Updated docker image
* A lot of various bugfixes and improvements


# Examples of GraphQL queries

```
{
  comments(blockchain: "steem", author: "ontofractal") {
    id,
    title,
    author,
    permlink,
    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,
    title,
    created,
    totalPayoutValue,
    pendingPayoutValue
  }
}
```

# Road map

In the next release, I plan to expand the capabilities of GraphQL resolvers and add filters, sorting, and a new type of queries for statistics.

Among future features:

* Convenient websockets APIs for accessing blockchain data
* Performant, low latency APIs
* Advanced filters and content display settings
* real-time streams of enriched blockchain events


# Technologies

* Elixir
* Phoenix
* GraphQL
* PostgreSQL

Read more about Glasnost and its roadmap in the [introduction post](https://steemit.com/steemit/@ontofractal/ann-introducing-glasnost-alpha-open-source-blog-and-app-server-for-steem-golos-blockchains)

# Development process
Glasnost is a single code base developed simultaneously both for Steem and Golos blockchains. Sustainable Glasnost development is made possible by generous support of Steem and Golos communities and @cyberfund program to support Golos open source ecosystem.
