#1 about 4 min

Introduction to Deno and installing the runtime natively

The Deno JavaScript runtime provides a modern alternative to traditional setups and can be quickly installed natively on any operating system.

#2 about 4 min

Initializing a project with built-in Deno development tools

Creating a new project via initialization commands automatically configures essential files alongside native language server protocol features for code editors.

#3 about 4 min

Testing and utilizing packages from the standard library

Running tests using the built-in runner eliminates third-party configuration while easily integrating curated packages from the native standard library.

#4 about 3 min

Managing dependency configuration and scripts without node modules

Defining execution tasks inside a dedicated configuration file modernizes dependency management by utilizing a centralized global cache instead of local module folders.

#5 about 4 min

Compiling TypeScript automatically with strict linting and formatting

Relying on built-in toolchains provides zero-configuration TypeScript compilation alongside native syntax checking and automatic code formatting tools.

#6 about 5 min

Exploring native core APIs and web standard support

Interacting with system files and running HTTP servers becomes streamlined using standardized native runtime commands and universal web APIs.

#7 about 2 min

Importing and accessing legacy Node modules natively

Importing traditional Node core packages natively ensures immediate backward compatibility when maintaining older application design patterns.

#8 about 3 min

Configuring execution capabilities through the explicit permissions model

Implementing an explicit permissions model requires deliberate access configuration to mitigate untrustworthy behavior from unverified external dependencies.

#9 about 6 min

Running existing Express and Node applications without modification

Executing complex pre-existing Express applications unmodified using native allowance commands eliminates tedious ecosystem migration efforts.
