Running Typescript workspaces with transpiled internal packages

Running TypeScript Workspaces with Transpiled Internal Packages

When working on large TypeScript projects, it is common to organize the codebase into multiple packages or modules. This helps in maintaining a clean and modular code structure. However, when it comes to running TypeScript workspaces with transpiled internal packages, it can be a bit challenging. In this article, we will explore different solutions to tackle this problem.

Solution 1: Using Symlinks

One way to handle transpiled internal packages in TypeScript workspaces is by using symlinks. Symlinks allow you to create a link to a directory or file in another location. By creating symlinks for the transpiled packages, you can easily reference them within your workspace.

To use symlinks, follow these steps:

1. Build the transpiled packages using the TypeScript compiler.
2. Create a symlink for each transpiled package using the following command:

ln -s /path/to/transpiled-package /path/to/workspace/node_modules/transpiled-package

Make sure to replace /path/to/transpiled-package with the actual path to the transpiled package, and /path/to/workspace with the actual path to your workspace.

Once the symlinks are created, you can import the transpiled packages in your TypeScript files as if they were regular dependencies.

Solution 2: Using npm/yarn link

Another approach to handle transpiled internal packages is by using the npm link or yarn link command. This command allows you to create a global link to a package, which can be referenced within your workspace.

To use npm link, follow these steps:

1. Build the transpiled packages using the TypeScript compiler.
2. Navigate to the transpiled package directory.
3. Run the following command:

npm link

After running the command, you will see a message indicating that the package has been successfully linked.

Next, navigate to your workspace directory and run the following command:

npm link transpiled-package

Make sure to replace transpiled-package with the actual name of the transpiled package.

Once the package is linked, you can import it in your TypeScript files as if it were a regular dependency.

Conclusion

Running TypeScript workspaces with transpiled internal packages can be a bit tricky, but with the help of symlinks or npm/yarn link, you can easily overcome this challenge. Choose the solution that best suits your project requirements and start enjoying the benefits of a modular codebase.
