# Description
This is a sample todo list implemented using pgx as the connector to a
PostgreSQL data store.
# Usage
Create a PostgreSQL database and run structure.sql into it to create the
necessary data schema.
Example:
createdb todo
psql todo < structure.sql
Build todo:
go build
## Connection configuration
The database connection is configured via DATABASE_URL and standard PostgreSQL environment variables (PGHOST, PGUSER, etc.)
You can either export them then run todo:
export PGDATABASE=todo
./todo list
Or you can prefix the todo execution with the environment variables:
PGDATABASE=todo ./todo list
## Add a todo item
./todo add 'Learn go'
## List tasks
./todo list
## Update a task
./todo update 1 'Learn more go'
## Delete a task
./todo remove 1
# Example Setup and Execution
jack@hk-47~/dev/go/src/github.com/jackc/pgx/examples/todo$ createdb todo
jack@hk-47~/dev/go/src/github.com/jackc/pgx/examples/todo$ psql todo < structure.sql
Expanded display is used automatically.
Timing is on.
