| 1 | +# Trigger.dev Configuration (v4) |
| 2 | + |
| 3 | +**Complete guide to configuring `trigger.config.ts` with build extensions** |
| 4 | + |
| 5 | +## Basic Configuration |
| 6 | + |
| 7 | +```ts |
| 8 | +import { defineConfig } from "@trigger.dev/sdk"; |
| 9 | + |
| 10 | +export default defineConfig({ |
| 11 | + project: "<project-ref>", // Required: Your project reference |
| 12 | + dirs: ["./trigger"], // Task directories |
| 13 | + runtime: "node", // "node", "node-22", or "bun" |
| 14 | + logLevel: "info", // "debug", "info", "warn", "error" |
| 15 | + |
| 16 | + // Default retry settings |
| 17 | + retries: { |
| 18 | + enabledInDev: false, |
| 19 | + default: { |
| 20 | + maxAttempts: 3, |
| 21 | + minTimeoutInMs: 1000, |
| 22 | + maxTimeoutInMs: 10000, |
| 23 | + factor: 2, |
| 24 | + randomize: true, |
| 25 | + }, |
| 26 | + }, |
| 27 | + |
| 28 | + // Build configuration |
| 29 | + build: { |
| 30 | + autoDetectExternal: true, |
| 31 | + keepNames: true, |
| 32 | + minify: false, |
| 33 | + extensions: [], // Build extensions go here |
| 34 | + }, |
| 35 | + |
| 36 | + // Global lifecycle hooks |
| 37 | + onStartAttempt: async ({ payload, ctx }) => { |
| 38 | + console.log("Global task start"); |
| 39 | + }, |
| 40 | + onSuccess: async ({ payload, output, ctx }) => { |
| 41 | + console.log("Global task success"); |
| 42 | + }, |
| 43 | + onFailure: async ({ payload, error, ctx }) => { |
| 44 | + console.log("Global task failure"); |
| 45 | + }, |
| 46 | +}); |
| 47 | +``` |

| 174 | +]; |
| 175 | +``` |
| 176 | + |
| 177 | +#### Additional NPM Packages |
| 178 | + |
| 179 | +Only use this for installing CLI tools, NOT packages you import in your code. |
| 180 | + |
| 181 | +```ts |
| 182 | +import { additionalPackages } from "@trigger.dev/build/extensions/core"; |
| 183 | + |
| 184 | +extensions: [ |
| 185 | + additionalPackages({ |
| 186 | + packages: ["wrangler"], // CLI tools and specific versions |
| 187 | + }), |
| 188 | +]; |
| 189 | +``` |
| 190 | + |
| 191 | +#### Additional Files |
| 192 | + |
| 193 | +```ts |
| 194 | +import { additionalFiles } from "@trigger.dev/build/extensions/core"; |
| 195 | + |
| 196 | +extensions: [ |
| 197 | + additionalFiles({ |
| 198 | + files: ["wrangler.toml", "./assets/**", "./fonts/**"], // Glob patterns supported |
| 199 | + }), |
| 200 | +]; |
| 201 | +``` |
| 202 | + |
| 203 | +### Environment & Build Tools |
| 204 | + |
| 205 | +#### Environment Variable Sync |
| 206 | + |
| 207 | +```ts |
| 208 | +import { syncEnvVars } from "@trigger.dev/build/extensions/core"; |
| 209 | + |
| 210 | +extensions: [ |
| 211 | + syncEnvVars(async (ctx) => { |
| 212 | + // ctx contains: environment, projectRef, env |
| 213 | + return [ |
| 214 | + { name: "SECRET_KEY", value: await getSecret(ctx.environment) }, |
| 215 | + { name: "API_URL", value: ctx.environment === "prod" ? "api.prod.com" : "api.dev.com" }, |
| 216 | + ]; |
| 217 | + }), |
| 218 | +]; |
| 219 | +``` |
| 220 | + |
| 221 | +#### ESBuild Plugins |
| 222 | + |
| 223 | +```ts |
| 224 | +import { esbuildPlugin } from "@trigger.dev/build/extensions"; |
| 225 | +import { sentryEsbuildPlugin } from "@sentry/esbuild-plugin"; |
| 226 | + |
| 227 | +extensions: [ |
| 228 | + esbuildPlugin( |
| 229 | + sentryEsbuildPlugin({ |
| 230 | + org: process.env.SENTRY_ORG, |
| 231 | + project: process.env.SENTRY_PROJECT, |
| 232 | + authToken: process.env.SENTRY_AUTH_TOKEN, |
| 233 | + }), |
| 234 | + { placement: "last", target: "deploy" } // Optional config |
| 235 | + ), |
| 236 | +]; |
| 237 | +``` |
| 238 | + |
| 239 | +## Custom Build Extensions |
| 240 | + |
| 241 | +```ts |
| 242 | +import { defineConfig } from "@trigger.dev/sdk"; |
| 243 | + |
| 244 | +const customExtension = { |
| 245 | + name: "my-custom-extension", |
| 246 | + |
| 247 | + externalsForTarget: (target) => { |
| 248 | + return ["some-native-module"]; // Add external dependencies |
| 249 | + }, |
| 250 | + |
| 251 | + onBuildStart: async (context) => { |
| 252 | + console.log(`Build starting for ${context.target}`); |
| 253 | + // Register esbuild plugins, modify build context |
| 254 | + }, |
| 255 | + |
| 256 | + onBuildComplete: async (context, manifest) => { |
| 257 | + console.log("Build complete, adding layers"); |
| 258 | + // Add build layers, modify deployment |
| 259 | + context.addLayer({ |
| 260 | + id: "my-layer", |
| 261 | + files: [{ source: "./custom-file", destination: "/app/custom" }], |
| 262 | + commands: ["chmod +x /app/custom"], |
| 263 | + }); |
| 264 | + }, |
| 265 | +}; |
| 266 | + |
| 267 | +export default defineConfig({ |
| 268 | + project: "my-project", |
| 269 | + build: { |
| 270 | + extensions: [customExtension], |
| 271 | + }, |
| 272 | +}); |
| 273 | +``` |
| 274 | + |
| 275 | +## Advanced Configuration |
| 276 | + |
| 277 | +### Telemetry |
| 278 | + |
| 279 | +```ts |
| 280 | +import { PrismaInstrumentation } from "@prisma/instrumentation"; |
| 281 | +import { OpenAIInstrumentation } from "@langfuse/openai"; |
| 282 | + |
| 283 | +export default defineConfig({ |
| 284 | + // ... other config |
| 285 | + telemetry: { |
| 286 | + instrumentations: [new PrismaInstrumentation(), new OpenAIInstrumentation()], |
| 287 | + exporters: [customExporter], // Optional custom exporters |
| 288 | + }, |
| 289 | +}); |
| 290 | +``` |
| 291 | + |
| 292 | +### Machine & Performance |
| 293 | + |
| 294 | +```ts |
| 295 | +export default defineConfig({ |
| 296 | + // ... other config |
| 297 | + defaultMachine: "large-1x", // Default machine for all tasks |
| 298 | + maxDuration: 300, // Default max duration (seconds) |
| 299 | + enableConsoleLogging: true, // Console logging in development |
| 300 | +}); |
| 301 | +``` |
| 302 | + |
| 303 | +## Common Extension Combinations |
| 304 | + |
| 305 | +### Full-Stack Web App |
| 306 | + |
| 307 | +```ts |
| 308 | +extensions: [ |
| 309 | + prismaExtension({ schema: "prisma/schema.prisma", migrate: true }), |
| 310 | + additionalFiles({ files: ["./public/**", "./assets/**"] }), |
| 311 | + syncEnvVars(async (ctx) => [...envVars]), |
| 312 | +]; |
| 313 | +``` |
| 314 | + |
| 315 | +### AI/ML Processing |
| 316 | + |
| 317 | +```ts |
| 318 | +extensions: [ |
| 319 | + pythonExtension({ |
| 320 | + scripts: ["./ai/**/*.py"], |
| 321 | + requirementsFile: "./requirements.txt", |
| 322 | + }), |
| 323 | + ffmpeg({ version: "7" }), |
| 324 | + additionalPackages({ packages: ["wrangler"] }), |
| 325 | +]; |
| 326 | +``` |
| 327 | + |
| 328 | +### Web Scraping |
| 329 | + |
| 330 | +```ts |
| 331 | +extensions: [ |
| 332 | + playwright({ browsers: ["chromium"] }), |
| 333 | + puppeteer(), |
| 334 | + additionalFiles({ files: ["./selectors.json", "./proxies.txt"] }), |
| 335 | +]; |
| 336 | +``` |
| 337 | + |
| 338 | +## Best Practices |
| 339 | + |
| 340 | +- **Use specific versions**: Pin extension versions for reproducible builds |
| 341 | +- **External packages**: Add modules with native addons to the `build.external` array |
| 342 | +- **Environment sync**: Use `syncEnvVars` for dynamic secrets |
| 343 | +- **File paths**: Use glob patterns for flexible file inclusion |
| 344 | +- **Debug builds**: Use `--log-level debug --dry-run` for troubleshooting |
| 345 | + |
| 346 | +Extensions only affect deployment, not local development. Use `external` array for packages that shouldn't be bundled. |
