char16t / right-now-pgsql

Potgresql + PostgREST backend for task tree that are available as flat list of tasks for execution right now

Pure PgSQL implementation of Right Now Task Engine. It's too difficult for support and improvements, so I had to switch to Neo4J. Read the details of the problem and solutions here: https://github.com/char16t/right-now

Use with PostgREST

Install:

1. Create database tasks
2. Execute backend/schema.sql in tasks database
3. Execute backend/postgrest.sql in tasks database

Run:

postgrest backend/postgrest.conf

Open:

http://localhost:3000/

http://localhost:3000/rpc/todo_list

Use with PostgreSQL
