- Install the hasura CLI
#Clone this repo
git clone https://github.com/hasura/graphql-workshop-2hrs
cd hasura-graphql-workshop/
docker-compose up -d
hasura console
#You might have to wait if you get an error on the command above, for hasura and postgres to start up
- On the Hasura console, create a users table, todo table
- Setup foreign keys and relationships
Users table:
| name | type | nullable | unique | default | primary |
|---|---|---|---|---|---|
| id | Text | no | yes | yes | |
| name | Text | no | no | no | |
| password | Text | no | no | no | |
| created_at | Timestamp | no | no | now() | |
| last_seen | Timestamp | no | no |
Todos table

Once you finish modelling, head to the migrations directory to see the actual files that have been created!
- Use Mutations to insert users & todos
