+# Packaging a VS Code Extension Using pnpm and VSCE
+
+VS Code’s `vsce` tool doesn't play nicely with `pnpm` out of the box; here’s a
+proven workaround using bundling and the `--no-dependencies` flag to get things
+running smoothly.
+
+---
+
+## Why pnpm + vsce can be problematic
+
+`vsce` relies on `npm list --production --parseable --depth=99999`, which fails
+under pnpm's symlink-based dependency management, often throwing
+`npm ERR! missing:` errors.  
+([github.com](https://github.com/microsoft/vscode-vsce/issues/421),
+[daydreamer-riri.me](https://daydreamer-riri.me/posts/compatibility-issues-between-vsce-and-pnpm/))
+
+---
+
+## Solution Overview
+
+1. **Bundle your extension** using a bundler such as **esbuild** or **Webpack**
+2. **Use `--no-dependencies`** when running `vsce package` and `vsce publish`
+
+Because all dependencies are bundled, `vsce` no longer needs to resolve them
+from `node_modules`.
+
+---
+
+## Step-by-Step Setup
+
+### 1. Install Tools
+
+```bash
+pnpm add -D @vscode/vsce esbuild
+```
+
+@vscode/vsce` is the CLI for packaging and publishing VSCode extensions. Recent
+versions (e.g., v3.6.0) support npm (≥6) and Yarn (1.x), but don't officially
+support pnpm.
+
+### 2\. Configure `package.json`
+
+Scripts Add build and packaging commands: jsonc Copy code
+
+```json
+{
+  "scripts": {
+    "vscode:prepublish": "pnpm run bundle",
+    "bundle": "esbuild ./src/extension.ts --bundle --outfile=out/main.js --external:vscode --format=cjs --platform=node --minify",
+    "package": "pnpm vsce package --no-dependencies",
+    "publish": "pnpm vsce publish --no-dependencies"
+  }
+}
+```
+
+- `vscode:prepublish`: runs before packaging; bundles source using esbuild
+- `bundle`: compiles `extension.ts` into `out/main.js` and excludes the `vscode`
+  module
+- `package` / `publish`: calls VSCE via pnpm, skipping dependency resolution
+
+### 3\. Why It Works
+
+By bundling dependencies manually, `vsce` doesn’t need to resolve them during
+packaging or publishing. The `--no-dependencies` option avoids pnpm’s symlink
+issues entirely.
+
+## Sample `package.json` Snippet
+
+```json
+{
+  "devDependencies": {
+    "@vscode/vsce": "^3.6.0",
+    "esbuild": "^0.XX.X"
+  },
+  "scripts": {
+    "vscode:prepublish": "pnpm run bundle",
+    "bundle": "esbuild ./src/extension.ts --bundle --outfile=out/main.js --external:vscode --format=cjs --platform=node --minify",
+    "package": "pnpm vsce package --no-dependencies",
+    "publish": "pnpm vsce publish --no-dependencies"
+  }
+}
+```
+
+### **Wrap-Up**
+
+Using **pnpm** with VS Code extensions involves a few extra steps because `vsce`
+doesn’t support pnpm’s dependency structure directly. The ideal workflow: _
+**Bundle your extension first**, then _ **Use `--no-dependencies`** to package
+and publish safely.
