The first build tool for compiling and bundling Vue components in a Deno runtime environment

  • Compiler
  • Bundler
  • Adapter


  • Vue is an approachable, incrementally adoptable JavaScript framework with an exciting ecosystem. Deno is a new runtime environment for JavaScript, built to address the shortcomings of node.js. We wanted to create a tool that let developers easily set up Vue applications in a Deno runtime environment. Meet vno!

How to use vno

  • You can use the vno Command Line Interface to quickly create a new Vue project in a Deno runtime
  • OR you can use the vno build method to compile an existing Vue file structure into a Deno-legible .js file

vno installation

  • vno requires the use of Deno version 1.10 or above
  • MacOS:
    • Run the following command in your terminal to install vno on your machine.
deno install --allow-net --unstable
  • WSL/Linux:
    • Open /home/<USERNAME>/bashrc with your editor of choice.
    • Add export PATH="/home/<USERNAME>/.deno/bin:$PATH to the end of the file.
    • Run the following command in your terminal to install vno on your machine.
sudo deno install --allow-net --unstable
  • Deno requires the --allow-net permission to run an installation

  • This feature and many of the others used in vno are still considered “unstable” for Deno. Run the command with --unstable to allow these resources to execute.

  • The force flag -f can be used if you want to overwrite an existing copy of the module

  • You can name the module in your path with the name flag -n or --name , ‘vno’ is the default name.

  • If you have not already added Deno bin into your path, you will need to do so.

    • MacOS: Copy the export path your terminal returns and paste it into your terminal
    • WSL/Linux: Replace root with your username and paste it into your terminal: export PATH="/home/<USERNAME>/.deno/bin:$PATH" install gif

a quick word about permissions

  • Deno is secure by default, which means that explicit permissions are required for certain tasks.
  • You can avoid responding to the permissions requests by flagging the installation script.
  • Most of our modules require both read and write permissions --allow-read & --allow-write
  • If you decide not to flag permissions at installation, you will be prompted in the terminal after executing a command.
  • If you would like to avoid writing out the permissions altogether, you can also use the -A or --allow-all tag

vno config

  • vno.config.json should be in the root of your project
  • following is a description of the object interface:
interface Config {
    entry: string;
      //entry is the path to root component's directory : i.e. './client/'
    root: string;
      //root is the filename of your root component : i.e. 'App'
    vue?: 2 | 3;
      //vue is the number 2 or 3 : 2 = vue v2.6.12 (default); 3 = vue v3.0.5 
    options?: {
      port?: number;
        //preferred port for the dev server : defaults to `3000`
      title?: string;
        //title of your project
      hostname?: string;
        //preferred host : defaults to ``


create a new project

  • Project name will become the directory that holds your project (you must CD into project directory after running the vno create command).
  • If the project name argument is omitted, then the project will be created in the current working directory.
  • Using vno create will give an option to build out a universal or single page application. Choosing ‘SPA’ will give you the option of choosing to add Vue Router, as well as choosing between Vue 2 or Vue 3 syntax.
vno create [project name]

vno create

  • OR If you’d rather not install:
deno run --allow-read --allow-write --allow-net --unstable create [project name]

run a build on a project

  • To invoke the build method and dynamically create bundled js and css files for your application, type the following into the terminal:
vno build


deno run --allow-read --allow-write --allow-net --unstable build

vno build

Scoped styling for CSS is currently not supported, but will be added to future builds

run a build on a project AND create a server configured for SSR

  • To invoke the build method and dynamically create bundled JS and CSS files, along with a server.ts for server side rendering your application, type the following into the terminal:
vno build --ssr


deno run --allow-read --allow-write --allow-net --unstable build --ssr

vno build ssr

run dev server includes live reload

  • Running the dev server dynamically runs a new build and runs the application on a module hosted server.
  • Native vno run dev command automatically enables live reload. Using Live Reload injects a WebSocket connection to build.js. Remove it with: vno run build
  • Invoke the dev server using the following commands:
vno run dev


deno run --allow-read --allow-write --allow-net --unstable run dev

vno run dev & live reload

vno as an API

initializing your application with the api

  • You can import vno into your application with the following URL : With a vno.config.json, no argument is needed The API will search for the config and apply it to your application
import { Factory } from '';

const vno = new Factory();
  • Without a vno.config.json, you can input the object directly into the Factory instance
import { Factory } from '';

const vno = Factory.create({
  root: "App",
  entry: "./"
  vue: 3,
  options: {
    port: 3000

await; will run a build on the entire application and compile it to a “vno-build” directory as one JavaScript file and one CSS file.

accessing component object storage

  • After running the build, parsed components are accessible inside the storage property on the Factory class.'App');

The argument accepted by the get method for storage is the component filename
