About The Project

Hasura is an extremely productive tool for quickly generating robust GraphQL APIs atop SQL databases. Hasura offers several extension points, including writing SQL functions in languages like PL/SQL or PL/pgSQL.

However, the developer workflow for writing SQL code in a Hasura-managed codebase is lacking. The default workflow does not require SQL code to be checked into an application's source tree like any other code. This can lead to error-prone manual workflows like copy/pasting existing functions into new migrations. Reviewing such migrations is nearly impossible.

sqrly offers an opinionated workflow wherein SQL functions are checked into a source tree as .sql files. While iterating on SQL code, sqrly will monitor for changed files and automatically apply them to a Postgres database. When it comes time to write out a Hasura migration, sqrly will gather files modified .sql files (according to git) and generate a new hasura migration with them.

Getting Started

$ npm install -g sqrly
$ sqrly watch --path path/to/sql/files --db postgres://...
-> Monitoring changes to path/to/sql/files/**/*.sql

# Add/edit some SQL code and it will be applied to the DB automatically.

-> Applying file path/to/sql/files/new_sql_function.sql
-> File applied.

# Ctrl-C to exit

$ git status
...
    added: path/to/sql/files/new_sql_function.sql

$ sqrly migrate \
    --name add_new_sql_function \
    --path path/to/sql/files \
    --hasura-dir path/to/hasura/files
-> Generating migration: add_new_sql_function
...
-> hasura migrate completed
