API Usage

The API is discoverable which means you can access the root resource at / and follow links to subresources from there but lets say you have a database named testdb with a table named testtable in the public schema you can then do the following operations:

Retrieve (GET) or update (PUT) a single row at:
/db/testdb/schemas/public/tables/testtable/rows/id

Retrieve rows (GET), update rows (PUT) or create a new row (POST) at:
/db/testdb/schemas/public/tables/testtable/rows

The above resources accepts URL encoded parameters where, limit and offset where applicable. Example:

GET a maximum of 10 rows where cost>100 at:
/db/testdb/schemas/public/tables/testtable/rows?where=cost%3E100&limit=10

The default and currently the only dataformat is JSON. POSTing or PUTing expects a single JSON object with properties corresponding to column names.

TODOs

• Use real primary key (current single row operations assume a primary key named id)
• Optionally use authenticated user/password to connect to DB
• Handle ORDER BY via orderby param
• Handle PostGIS data
• Allow raw SQL queries?
• Handle DDL stuff?
