#esbuild Plugin Resolution Issue with Virtual Module
primal sandalBOT
To address your issue with esbuild plugin resolution for virtual modules in a Trigger.dev project, I can provide some guidance based on the available information.
The Trigger.dev build system uses esbuild, and it allows for customization of the build process through extensions. For your specific case with a custom esbuild plugin, you can use the esbuildPlugin extension provided by Trigger.dev to integrate your plugin into the build process.
Here's how you can set up your custom esbuild plugin in the trigger.config.ts file:
import { defineConfig } from "@trigger.dev/sdk/v3";
import { esbuildPlugin } from "@trigger.dev/build/extensions";
import yourCustomPlugin from './path-to-your-custom-plugin';
export default defineConfig({
project: "<project ref>",
build: {
extensions: [
esbuildPlugin(
yourCustomPlugin(),
{ placement: "last", target: "deploy" }
),
],
},
});
This setup is based on the information from the Trigger.dev documentation on esbuild plugins.
For your specific issue with resolving file imports within a virtual module, you need to ensure that your custom plugin is correctly setting the resolveDir for the virtual module. Here's a general structure that might help:
const yourCustomPlugin = () => ({
name: 'your-custom-plugin',
setup(build) {
build.onResolve({ filter: /^virtual:/ }, (args) => {
return { path: args.path, namespace: 'virtual-namespace' }
})build.onLoad({ filter: /.*/, namespace: 'virtual-namespace' }, (args) => {
// Your virtual module content generation logic here
const contents = export { sendWelcomeEmail } from '${build.initialOptions.absWorkingDir}/src/lib/email.ts'
return {
contents,
resolveDir: build.initialOptions.absWorkingDir, // Set the resolve directory to the project root
}
})
}
})
In this example, `build.initialOptions.absWorkingDir` is used to set the `resolveDir` to the project root, which should help esbuild resolve the imports correctly.
If you're still encountering issues, you might want to use the debug logging feature of Trigger.dev to get more information about the build process. You can do this by running:
npx trigger.dev@latest dev --log-level debug
or
npx trigger.dev@latest deploy --log-level debug
This information comes from the [Trigger.dev documentation on troubleshooting build extensions](<https://trigger.dev/docs/config/extensions/overview#troubleshooting>).
If these suggestions don't resolve your issue, you might want to consider reaching out to the Trigger.dev community for more specific help. You can [join their Discord community](<https://trigger.dev/discord>) or [open an issue on GitHub](<https://github.com/triggerdotdev/trigger.dev/issues>) for further assistance.

ok. I think the issue is with the path resolution.

@primal sandal
I believe the issue is somewhere in how i'm resolving the paths in the plugin
build.onResolve({ filter: /^\.\/src\/lib\/([^/]+)$/ }, args => {
// Extract the filename from the import
const filename = args.path.split('/').pop();
// Derive the full path based on the current working directory
const srcLibPath = resolve(build.initialOptions.absWorkingDir ?? process.cwd(), 'src', 'lib');
const fullPath = resolve(srcLibPath, `${filename}.ts`);
console.log(`[triggerkit] Original import: ${args.path}`);
console.log(`[triggerkit] Resolved path: ${fullPath}`);
return {
path: fullPath,
namespace: 'file'
};
});
build.onResolve({ filter: /^virtual:triggerkit$/ }, (args) => {
console.log(`[triggerkit] Resolving path: ${args.path}`);
return {
path: args.path,
namespace: NAMESPACE
};
});
But this is producing [ERROR] Could not resolve "../lib/email"

Let me check the knowledge base for you again. One moment! :books:
Based on the code snippet you've provided and the error message you're seeing, it appears that the issue is indeed related to path resolution in your custom esbuild plugin. Let's analyze the problem and suggest a potential solution.
The error message [ERROR] Could not resolve "../lib/email" indicates that the plugin is trying to resolve a relative path (../lib/email) which doesn't match the filter you've set in your onResolve hook (/^\.\/src\/lib\/([^/]+)$/).
To address this issue, you can modify your plugin to handle both relative and absolute paths. Here's a suggested modification to your plugin:
import { resolve, dirname } from 'path';
// ... other parts of your plugin ...
build.onResolve({ filter: /^(\.\.?\/.*|src\/lib\/.*|virtual:triggerkit)$/ }, (args) => {
console.log(`[triggerkit] Resolving path: ${args.path}`);
if (args.path === 'virtual:triggerkit') {
return {
path: args.path,
namespace: NAMESPACE
};
}
// Handle relative paths
const fullPath = resolve(args.resolveDir, args.path);
// Ensure the path ends with .ts
const finalPath = fullPath.endsWith('.ts') ? fullPath : `${fullPath}.ts`;
console.log(`[triggerkit] Original import: ${args.path}`);
console.log(`[triggerkit] Resolved path: ${finalPath}`);
return {
path: finalPath,
namespace: 'file'
};
});
This modification does the following:
- It expands the filter to catch relative paths (
..and.), paths starting withsrc/lib/, and your virtual module. - It uses
args.resolveDiras the base for resolving relative paths. This is provided by esbuild and represents the directory of the file containing the import. - It ensures that the resolved path ends with
.ts.
To integrate this plugin with Trigger.dev, you can use the esbuildPlugin extension in your trigger.config.ts file as mentioned in the Trigger.dev documentation on esbuild plugins:
import { defineConfig } from "@trigger.dev/sdk/v3";
import { esbuildPlugin } from "@trigger.dev/build/extensions";
import yourCustomPlugin from './path-to-your-custom-plugin';
export default defineConfig({
project: "<project ref>",
build: {
extensions: [
esbuildPlugin(
yourCustomPlugin(),
{ placement: "last", target: "deploy" }
),
],
},
});
If you're still encountering issues after these changes, you might want to use the debug logging feature of Trigger.dev to get more detailed information about the build process. You can do this by running:
npx trigger.dev@latest dev --log-level debug
or
npx trigger.dev@latest deploy --log-level debug
This information comes from the Trigger.dev documentation on troubleshooting build extensions.
If these suggestions don't fully resolve your issue, consider reaching out to the Trigger.dev Discord community for more specific help, as they might have more experience with complex esbuild plugin scenarios in the context of Trigger.dev projects.

Let me check the knowledge base for you again. One moment! :books:
Based on the code snippets you've provided, it seems you're using a custom esbuild plugin called triggerkit for your Trigger.dev project. The issue you're facing is related to resolving imports within a virtual module. Let's analyze the problem and suggest some potential solutions.
-
Virtual Module Resolution:
Your plugin is correctly handling the resolution of the virtual module itself. You have multipleonResolvehooks that catch different variations of the virtual module ID. -
Import Resolution Within Virtual Module:
The problem likely occurs when trying to resolve the imports that are generated within the virtual module content. YouronLoadhook for the virtual module is generating content, but it's not providing aresolveDirfor the imports within that content.
To address this, you can modify your onLoad hook to include a resolveDir. Here's a suggested modification:
build.onLoad({ filter: /.*/, namespace: NAMESPACE }, async () => {
const currentTime = Date.now();
if (!virtualModuleContent || currentTime - lastScanTime > 2000) { // 2 seconds cache
const { exportedFunctions, discoveredEnvVars } = await scanForFunctions(
resolvedIncludeDirs,
include,
exclude
);
virtualModuleContent = generateEntryModule(exportedFunctions, discoveredEnvVars);
lastScanTime = currentTime;
}
return {
contents: virtualModuleContent,
loader: 'ts',
resolveDir: process.cwd(), // Add this line
};
});
By adding resolveDir: process.cwd(), you're telling esbuild to resolve imports in the virtual module relative to the current working directory.
- Additional Resolution Hook:
You might also need to add an additionalonResolvehook to handle the imports within your virtual module. Here's an example:
build.onResolve({ filter: /^\.\.?\/.*/ }, (args) => {
if (args.namespace === NAMESPACE) {
// This is an import from within our virtual module
const resolvedPath = resolve(process.cwd(), args.path);
return {
path: resolvedPath,
namespace: 'file',
};
}
});
This hook will handle relative imports within your virtual module, resolving them relative to the project root.
- Debugging:
To help debug the issue, you can add more logging in your plugin. For example:
build.onResolve({ filter: /.*/ }, (args) => {
console.log(`[triggerkit] Resolving: ${args.path} from ${args.importer}`);
return null; // Let esbuild handle it
});
This will log all resolution attempts, which can help you understand what paths esbuild is trying to resolve.
- Using Trigger.dev's esbuildPlugin:
As mentioned in the Trigger.dev documentation on esbuild plugins, you should wrap your custom plugin with theesbuildPluginfunction provided by Trigger.dev. Update yourtrigger.config.tslike this:
import { defineConfig } from "@trigger.dev/sdk/v3";
import { esbuildPlugin } from "@trigger.dev/build/extensions";
import { triggerkit } from "vite-plugin-triggerkit";
export default defineConfig({
dirs: ["./src/trigger"],
build: {
external: ['vite-plugin-triggerkit', 'fsevents', 'lightningcss'],
extensions: [
esbuildPlugin(
triggerkit({
includeDirs: ['src/lib', 'src/lib/server']
}),
{ placement: "last", target: "deploy" }
),
]
}
});
If you're still encountering issues after implementing these suggestions, you might want to use the debug logging feature of Trigger.dev as mentioned in the documentation on troubleshooting build extensions:
npx trigger.dev@latest dev --log-level debug
