You can use the CLI to build custom pieces for the platform. This process compiles the pieces and exports them as a `.tgz` packed archive.
### How It Works
The CLI scans the `packages/pieces/` directory for the specified piece. It checks the **name** in the `package.json` file. If the piece is found, it builds and packages it into a `.tgz` archive.
### Usage
To build a piece, follow these steps:
1. Ensure you have the CLI installed by cloning the repository.
2. Run the following command:
```bash
npm run build-piece
```
You will be prompted to enter the name of the piece you want to build. For example:
```bash
? Enter the piece folder name : google-drive
```
The CLI will build the piece and you will be given the path to the archive. For example:
```bash
Piece 'google-drive' built and packed successfully at dist/packages/pieces/community/google-drive
```
