FAQPage Schema

How do I configure deno.json for a new Deno project?▼

To configure deno.json for a new Deno project, define your import maps, specify JSR package dependencies, and set up permission rules. This establishes a secure execution environment and centralizes dependency management using best practices.

What is the best way to manage dependencies in Deno?▼

The best way to manage Deno dependencies is using JSR packages via the jsr: import syntax. You should use npm as a fallback option and actively avoid deno.land/x to ensure modern, secure package management.

How do I run Deno CLI workflows for formatting, linting, and testing?▼

You run Deno CLI workflows by executing deno fmt for code formatting, deno lint for static analysis, and deno test for running test suites. These built-in tools provide a standard development workflow without external dependencies.

Can I use npm packages in a Deno project?▼

Yes, you can use npm packages in a Deno project as a fallback when JSR equivalents are unavailable. Configuring your deno.json correctly allows you to import and manage both jsr and npm dependencies securely.

Why should I avoid deno.land/x when starting a new project?▼

You should avoid deno.land/x because JSR provides a more modern and secure package registry. Using jsr: imports in your deno.json ensures better compatibility with built-in Deno tooling and standardized dependency management.
