Funding HAF Plug & Play Development #2

Breakdown of fund usage:

2 dedicated servers (Development and Production: $130 x 2)

Development costs (I am the main developer and I am working with a frontend developer to make/maintain an onboarding website and example implementations of HAF-based Plug & Play)

Administrative costs (I am working with a dedicated admin to handle Plug & Play onboarding and setup for clients)

Summary of what I'm offering the community:

A public, HAF Plug & Play node

Database schema design services, to populate custom tables and functions

Endpoint design to retrieve custom data sets that Hive dApps need

Support for the universal custom_json ops like community and follow

API streaming of custom_json ops

Subscription-based access (still under deliberation)

Help with setting up public HAF Plug & Play node

Current status:

The code is on GitHub: https://github.com/imwatsi/haf-plug-play

Preparing a public beta version to be released next week

Initiated communication with

@brianoflondon to support Podping's custom_json and API endpoints

I'm working on supporting the parsing of post json_metadata, which will enable apps that use json in posts and comments to populate state for various content related features (still in Alpha stage)

Progress Report (V1 target):

Core code:

[100%] HAF sync script: connects to the `hive_fork_manager` extension, extracts `custom_json` ops and saves them in a PostgreSQL database [100%] Main "plug" structures: SQL function structures, table schema designs, JSONRPC endpoint design structures to make "plugs" configurable and independent of other plug data

Plug code:

1) Stores, synchronizes and avails historical and state-based data from custom_json ops. It uses PostgreSQL functions to populate tables that store historical operations and secondary functions to populate tables that store derived state.

[100%] PostgreSQL database, functions and table schemas [100%] App and plug definitions

2) JSONRPC endpoints to handle data requests from apps.

[100%] Follow plug: historical `follow` operations and Hive accounts' followers list [100%] Reblog plug: historical `reblog` operations and endpoints to retrieve all reblogs made on a particular post or author, optionally filterable by block_range [40%] Community plug: historical `community` operations and the state of community related ops like subscribe, unsubscribe, etc (still work-in-progress)
