Trigger.dev Configuration
Configure your Trigger.dev project with trigger.config.ts and build extensions.
When to Use
- Setting up a new Trigger.dev project
- Adding database support (Prisma, TypeORM)
- Configuring browser automation (Playwright, Puppeteer)
- Adding media processing (FFmpeg)
- Running Python scripts from tasks
- Syncing environment variables
- Installing system packages
Basic Configuration
// trigger.config.ts
import { defineConfig } from "@trigger.dev/sdk";
export default defineConfig({
project: "<project-ref>",
dirs: ["./trigger"],
runtime: "node", // "node", "node-22", or "bun"
logLevel: "info",
retries: {
enabledInDev: false,
default: {
maxAttempts: 3,
minTimeoutInMs: 1000,
maxTimeoutInMs: 10000,
factor: 2,
},
},
build: {
extensions: [], // Add extensions here
},
});
Common Build Extensions
Prisma
import { prismaExtension } from "@trigger.dev/build/extensions/prisma";
export default defineConfig({
// ...
build: {
extensions: [
prismaExtension({
schema: "prisma/schema.prisma",
migrate: true,
directUrlEnvVarName: "DIRECT_DATABASE_URL",
}),
],
},
});
Playwright (Browser Automation)
import { playwright } from "@trigger.dev/build/extensions/playwright";
extensions: [
playwright({
browsers: ["chromium"], // or ["chromium", "firefox", "webkit"]
}),
]
Puppeteer
import { puppeteer } from "@trigger.dev/build/extensions/puppeteer";
extensions: [puppeteer()]
// Set env var: PUPPETEER_EXECUTABLE_PATH="/usr/bin/google-chrome-stable"
FFmpeg (Media Processing)
import { ffmpeg } from "@trigger.dev/build/extensions/core";
extensions: [
ffmpeg({ version: "7" }),
]
// Automatically sets FFMPEG_PATH and FFPROBE_PATH
Python
import { pythonExtension } from "@trigger.dev/build/extensions/python";
extensions: [
pythonExtension({
scripts: ["./python/**/*.py"],
requirementsFile: "./requirements.txt",
devPythonBinaryPath: ".venv/bin/python",
}),
]
// Usage in tasks:
const result = await python.runScript("./python/process.py", ["arg1"]);
System Packages (apt-get)
import { aptGet } from "@trigger.dev/build/extensions/core";
extensions: [
aptGet({
packages: ["imagemagick", "curl"],
}),
]
Additional Files
import { additionalFiles } from "@trigger.dev/build/extensions/core";
extensions: [
additionalFiles({
files: ["./assets/**", "./templates/**"],
}),
]
Environment Variable Sync
import { syncEnvVars } from "@trigger.dev/build/extensions/core";
extensions: [
syncEnvVars(async (ctx) => {
return [
{ name: "API_KEY", value: await getSecret(ctx.environment) },
{ name: "ENV", value: ctx.environment },
];
}),
]
Common Extension Combinations
Full-Stack Web App
extensions: [
prismaExtension({ schema: "prisma/schema.prisma", migrate: true }),
additionalFiles({ files: ["./assets/**"] }),
syncEnvVars(async (ctx) => [...envVars]),
]
AI/ML Processing
extensions: [
pythonExtension({
scripts: ["./ai/**/*.py"],
requirementsFile: "./requirements.txt",
}),
ffmpeg({ version: "7" }),
]
Web Scraping
extensions: [
playwright({ browsers: ["chromium"] }),
additionalFiles({ files: ["./selectors.json"] }),
]
Global Lifecycle Hooks
export default defineConfig({
// ...
onStartAttempt: async ({ payload, ctx }) => {
console.log("Task starting:", ctx.task.id);
},
onSuccess: async ({ payload, output, ctx }) => {
console.log("Task succeeded");
},
onFailure: async ({ payload, error, ctx }) => {
console.error("Task failed:", error);
},
});
Machine Defaults
export default defineConfig({
// ...
defaultMachine: "medium-1x",
maxDuration: 300, // seconds
});
Telemetry Integration
import { PrismaInstrumentation } from "@prisma/instrumentation";
export default defineConfig({
// ...
telemetry: {
instrumentations: [new PrismaInstrumentation()],
},
});
Best Practices
- Pin versions for reproducible builds
- Use
syncEnvVarsfor dynamic secrets - Add native modules to
build.externalarray - Debug with
--log-level debug --dry-run
Extensions only affect deployment, not local development.
See references/config.md for complete documentation.

trigger-realtime
Subscribe to Trigger.dev task runs in real-time from frontend and backend. Use when building progress indicators, live dashboards, streaming AI/LLM responses, or React components that display task status.
triggerdotdev/skills
trigger-setup
Set up Trigger.dev in your project. Use when adding Trigger.dev for the first time, creating trigger.config.ts, or initializing the trigger directory.
triggerdotdev/skills
trigger-agents
AI agent patterns with Trigger.dev - orchestration, parallelization, routing, evaluator-optimizer, and human-in-the-loop. Use when building LLM-powered tasks that need parallel workers, approval gates, tool calling, or multi-step agent workflows.
triggerdotdev/skills
trigger-tasks
Build AI agents, workflows and durable background tasks with Trigger.dev. Use when creating tasks, triggering jobs, handling retries, scheduling cron jobs, or implementing queues and concurrency control.
triggerdotdev/skills
trigger-cost-savings
Analyze Trigger.dev tasks, schedules, and runs for cost optimization opportunities. Use when asked to reduce spend, optimize costs, audit usage, right-size machines, or review task efficiency. Requires Trigger.dev MCP tools for run analysis.
triggerdotdev/trigger.dev
span-timeline-events
Use when adding, modifying, or debugging OTel span timeline events in the trace view. Covers event structure, ClickHouse storage constraints, rendering in SpanTimeline component, admin visibility, and the step-by-step process for adding new events.
