### Clone and run the preorder template with Bun

Source: https://effectstream.github.io/docs/home/templates/preorder

Clones the repository, installs dependencies, and starts the local development stack. `bun run dev` is `NODE_ENV=development bunx orchestrator start`, which reads `start.dev.ts` and brings up all services in dependency order.

```bash
git clone https://github.com/effectstream/effectstream.git  

cd effectstream/templates/preorder  

  

bun install          # standalone; inside the monorepo run ./link.sh instead  

bun run dev          # boots the whole local stack
```

--------------------------------

### Build and run with Docker

Source: https://effectstream.github.io/docs/home/templates/evm-midnight

Builds and runs the Docker image, which installs Bun, Node, Foundry, and Compact, pre-warms the solc cache, and starts the orchestrator. On Apple Silicon, set DOCKER_DEFAULT_PLATFORM to linux/amd64. The test suite runs inside the container with `bun run test`.

```bash
# On macOS Apple Silicon  

export DOCKER_DEFAULT_PLATFORM=linux/amd64  

  

docker build -f ./Dockerfile . -t evm-midnight  

docker run -p 10599:10599 -p 9999:9999 -p 8545:8545 -p 8546:8546 \  

           -p 8088:8088 -p 6300:6300 -p 9944:9944 -p 4747:4747 evm-midnight  

  

# Run the test suite inside the container  

docker run evm-midnight bun run test  
```

### Clone and Run Development Environment

Source: https://effectstream.github.io/docs/home/templates/batcher-validations

Commands to clone the repository, install dependencies, and start the development services including PGLite, Hardhat, sync node, batcher, and frontend.

```bash
git clone https://github.com/effectstream/effectstream.git

cd effectstream/templates/batcher-validations

  

bun install          # standalone; inside the monorepo run ./link.sh instead

bun run dev          # PGLite, Hardhat + deploy, sync node, batcher, frontend
```

--------------------------------

### Clone and run the template with link.sh and bun run dev

Source: https://effectstream.github.io/docs/home/templates/projected-nft-preorder

Clones the effectstream repository, navigates to the projected-nft-preorder template, runs link.sh to install dependencies and symlink local packages, then starts the development environment with bun run dev. The first run downloads the YACI DevKit and Cardano node, so it takes longer.

```bash
git clone https://github.com/effectstream/effectstream.git  

cd effectstream/templates/projected-nft-preorder  

  
# Inside the monorepo, use link.sh — it installs npm deps and then symlinks  
# every @effectstream/* package to its local source. Standalone copies of the  
# template use `bun install` instead.  
./link.sh  

  
# Starts PGLite, YACI DevKit and Dolos; mints a test NFT and writes the  
# Hololocker script hash; then starts the sync node and the frontend.  
bun run dev  

```

--------------------------------

### Complete Batcher Setup with Effection

Source: https://effectstream.github.io/docs/home/components/batcher/overview

This example shows the complete setup for the Effectstream Batcher. It creates an EffectstreamL2DefaultAdapter with a contract address, private key, fee, and sync protocol name. Then it creates a Batcher with polling interval, port, HTTP server, event system, and empty adapters, using FileStorage. The adapter is added with hybrid criteria (time window and max batch size) and set as default target. State transitions for 'startup' and 'batch:submit' are added for monitoring. Finally, the batcher is run with Effection's main and suspend.

```typescript
import { main, suspend } from "effection";  

import { Batcher, FileStorage, EffectstreamL2DefaultAdapter } from "@effectstream/batcher-sdk";  

  

// 1. Create adapter  

const adapter = new EffectstreamL2DefaultAdapter(  

  "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb",  // Contract address  

  process.env.PRIVATE_KEY!,                       // Private key  

  0n,                                              // Fee  

  "mainEvmRPC"                                     // Sync protocol name  

);  

  

// 2. Create batcher  

const batcher = new Batcher({  

  pollingIntervalMs: 1000,  

  port: 3334,  

  enableHttpServer: true,  

  enableEventSystem: true,  

  adapters: {}  // Start empty, add dynamically  

}, new FileStorage("./batcher-data"));  

  

// 3. Wire adapter with criteria  

batcher.addBlockchainAdapter("ethereum", adapter, {  

  criteriaType: "hybrid",  

  timeWindowMs: 5000,  

  maxBatchSize: 50  

}).setDefaultTarget("ethereum");  

  

// 4. Add monitoring  

batcher.addStateTransition("startup", ({ publicConfig }) => {  

  console.log(`🚀 Batcher started on port ${publicConfig.port}`);  

});  

  

batcher.addStateTransition("batch:submit", ({ txHash }) => {  

  console.log(`🚀 Batch submitted: ${txHash}`);  

});  

  

// 5. Run with Effection  

main(function* () {  

  yield* batcher.runBatcher();  

  yield* suspend();  

});  

  

```

### Define and register a database migration with start(...)

Source: https://effectstream.github.io/docs/home/effectstream-engine/database

These three files define and register a database migration: the SQL creates the `inputs_log` table in the `public` schema, the migration-order file pairs the SQL text with a name, and the node entry point passes the migration table to `start(...)`. The engine applies any unrun migrations in array order during startup.

```sql
CREATE TABLE inputs_log (  
  id SERIAL PRIMARY KEY,  
  signer TEXT NOT NULL,  
  payload JSONB NOT NULL,  
  block_height INTEGER NOT NULL  
);  
```

```typescript
import type { DBMigrations } from "@effectstream/runtime";  
import initSql from "./migrations/000-init.sql" with { type: "text" };  
  
export const migrationTable: DBMigrations[] = [  
  { name: "000-init.sql", sql: initSql },  
];  
```

```typescript
import { migrationTable } from "@my-app/database";  
  
yield* start({  
  appName: "my-app",  
  appVersion: "1.0.0",  
  syncInfo: toSyncProtocolWithNetwork(config),  
  migrations: migrationTable,  
  // …grammar, gameStateTransitions, apiRouter  
});  
```

--------------------------------

### Install @effectstream/npm-avail-light-client with bun or npm
