Hello there! 🦕 Welcome to the world of Deno and TypeScript. If you're encountering errors when trying to deploy TypeScript projects in Deno, there are a few steps you can take to troubleshoot and resolve the issues:
1. Check TypeScript Version: Ensure that you're using a version of TypeScript that is compatible with Deno. You can find out the version of TypeScript that Deno is built with by running
deno --version in your terminal.
2. Review Import Statements: Deno requires explicit module specifiers, including the file extension. Make sure your import statements include the .ts extension where necessary.
3. Permissions: Deno is secure by default, which means it runs in a sandbox. If your project requires access to the network, file system, or environment variables, you need to explicitly grant these permissions. For example, if your project needs to read from the disk, you would run it with deno run --allow-read your_script.ts.
4. Type Checking: If you're getting type errors, it could be due to dependencies on the DOM or other global objects that are not included by default in Deno. You can use a tsconfig.json to configure TypeScript for Deno and include the necessary type libraries.
5. Import Maps: If you're using third-party modules that don't follow Deno's module resolution strategy, you might need to use an import map to specify how to resolve these modules.
6. Check the Documentation: The documentation provides a wealth of information on deploying and embedding Deno, TypeScript in Deno, and advanced topics that might be relevant to your project. Make sure to review the relevant sections to understand best practices and requirements.
If you're still having trouble after going through these steps, could you provide a specificerror message or describe the issue in more detail? That way, I can offer more targeted advice to help you get your TypeScript project up and running with Deno.
