Introducing the Jaina CLI and SDKs

What shipped

Today we shipped four packages alongside the platform:

All four are open source, MIT licensed.

The CLI

npm install -g jaina-cli

jaina login                       # OAuth in your browser
jaina projects list               # what's in your account
jaina projects create my-game     # new project

# Sync workflow
jaina pull my-game/level-1        # download package to ./level-1/
# ... edit model.json or files locally ...
jaina push ./level-1              # upload your changes

# Code generation
jaina codegen my-game --lang csharp --output ./Models/
jaina codegen my-game --lang typescript --output ./types/

TypeScript example

import { JainaClient } from '@jaina/sdk';

const jaina = new JainaClient({
  apiKey: process.env.JAINA_API_KEY!,
});

const enemies = await jaina.records.list<Enemy>('my-game', 'enemy', {
  filter: { 'data.hp': { gte: 50 } },
});

await jaina.records.create('my-game', 'enemy', {
  name: 'Goblin',
  hp: 20,
  attack: 3,
});

C# example (Unity-friendly)

using Jaina.Client;

var client = new JainaClient(apiKey: System.Environment.GetEnvironmentVariable("JAINA_API_KEY"));

var enemies = await client.Records.ListAsync<Enemy>("my-game", "enemy");
foreach (var e in enemies.Items)
{
    UnityEngine.Debug.Log($"{e.Name} (HP {e.Hp})");
}

Python example

from jaina import JainaClient

with JainaClient(api_key=os.environ["JAINA_API_KEY"]) as jaina:
    enemies = jaina.records.list("my-game", "enemy", model=Enemy)
    for e in enemies.items:
        print(f"{e.name} (HP {e.hp})")

What's next

The CLI and SDKs are at v0.2 with 249 tests passing across the three language clients. We're focused on coverage and ergonomics, not surface area, for the next few months. If something is awkward, open an issue — that's the fastest path to a fix.
