An example application with deno.

This reflects Deno as of v0.3.1.

This file contains all the runtime type information, which can be used to supply an editor, like VSCode with the type information. This was generated from a custom build of deno, but you can simply replace this with whatever version of deno you are running, by doing something like:

$ deno --types > lib/lib.deno_runtime.d.ts

If you clone the repository, you simply need an install of deno in your path and run the following:

$ deno main.ts

Which should output something like:

Architecture: x64
Platform: mac

args: [ "main.ts" ]

There is also a basic tests which you can run via:

$ deno test.ts

Which should output:

If you clone this repository and use VSCode, you should be able to get all the intellisense available for the Deno environment. TypeScript does not support module IDs that end in .ts, but via the deno_ls_plugin it is able to patch TypeScript when using VSCode.

This does require you to do an npm install or yarn install after cloning the package and using the Workspace Version of TypeScript.

NOTE Deno does not use any package managers, the package.json only exists to facilitate installing the two required packages for VSCode to be able to give the full editing experience.

NOTE Because plugins are only active when using the language services, they do not affect tsc which means that when you try to run tsc it will report errors on module IDs which end with .ts.

In order to provide intellisense for remote modules, the tsconfig.json leverages baseUrl and paths to allow TypeScript to resolve modules that exist in the local Deno cache:

{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      // Paths have to be relative to `baseUrl`
      "http:https://*": [
        // This is the OSX location (assumine root is two levels up)
        "../../Library/Caches/deno/deps/http/*",
        // This is the typical location a Linux
        "../../.cache/deno/deps/http/*"
      ],
      "https://*": [
        // This is the OSX location (assumine root is two levels up)
        "../../Library/Caches/deno/deps/https/*",
        // This is the typical location a Linux
        "../../.cache/deno/deps/https/*"
      ]
    }
  }
}

The Deno cache defaults to the standard location based on operating system. See the notes in the Deno Manual on this. It can be overridden by setting the DENO_DIR environment variable. paths works off of relative paths from the baseURl, so the values may need to be adjusted based on your local configuration.

Also, you will not get intellisense until the remote modules are at least retrieved once.
