Overview

  • Vue is an approachable javascript framework with an exciting ecosystem with remarkable versatility. Deno is a runtime environment intent on improving the shortcomings of node.js. We wanted to be able to leverage the Vue framework in a Deno runtime environment, and vno makes that possible.

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
  • run the following command in your terminal to install vno on your machine.
deno install --allow-net --unstable https://deno.land/x/vno/install/vno.ts
  • 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.

    • Copy the export path your terminal returns and paste it into your terminal

a quick word about permissions

  • Deno is secure by default, this 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 module requires 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.
  • note: 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 `0.0.0.0`
    };
  }

CLI

create a new project

  • Project name will become the directory that holds your project (you must CD into project directory after running create command).
  • If project name argument is omitted, then project will be created in current working directory.
vno create [project name]

  • OR If you'd rather not install:
deno run --allow-read --allow-write --allow-net --unstable https://deno.land/x/vno/install/vno.ts 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

OR

deno run --allow-read --allow-write --allow-net --unstable https://deno.land/x/vno/install/vno.ts build

vno build

It is important to know that as of now, scoped styling is not supported

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

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

OR

deno run --allow-read --allow-write --allow-net --unstable https://deno.land/x/vno/install/vno.ts 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
    • Live reload injects a WebSocket connection to build.js. Remove it with: vno run build
  • Invoke the dev server like so:
vno run dev

OR

deno run --allow-read --allow-write --allow-net --unstable https://deno.land/x/vno/install/vno.ts 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 : https://deno.land/x/vno/dist/mod.ts 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 'https://deno.land/x/vno/dist/mod.ts';

const vno = new Factory();
await vno.build();

without a vno.config.json, you can input the object directly into the Factory instance

import { Factory } from 'https://deno.land/x/vno/dist/mod.ts';

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

await vno.build();

vno.build() 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.
vno.storage.get('App');

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