So, what exactly is Dojo today?
Dojo is a modern TypeScript framework designed from the ground up to make building web applications easy and fun. Dojo has always been focussed on providing compatibility with the emerging web standards, interoperability with the wider web development ecosystem and a batteries included approach with intelligent defaults. Dojo aims to provide developer friendly, intuitive APIs without compromising the experience for your users. Over the last 2 years since the initial 2.0.0 release, Dojo has continued to evolve across the entire framework, with core features that aim to cover every aspect of modern web application development.
Core Dojo features:
- Custom Dojo rendering engine for widgets and DOM nodes
- Flexible, composable functionality with Dojo middleware
- Zero config Custom element generation, output any Dojo widget as a custom element
- Test renderer for testing Dojo widgets
- Routing and Store functionality
- Bespoke Dojo build commands, with intelligent defaults
- Automatic route based and configuration driven code splitting
- Conditionally load polyfills depending on usage and browser capabilities
- Out of the box PWA support with a just a few lines of configuration
- Build time rendering, inline html and CSS at build time including support for fully static sites
- Dojo Blocks, execute modules at build time and load the block bundle at runtime
- Comprehensive widget library
- Dojo commands for creating applications and widget libraries
- Dojo Parade, a complete, automated widget example and documentation generation tool
- Seamless integration with Vercel, with built-in support for Dojo
- Dojo Codesandbox integration and standard template for getting started quickly
And much more! Over the coming months, hopefully I'll be covering a number of these features here on Dojo Tips.
Let's get started with the Dojo CLI
The easiest way to get started with Dojo is by using the Dojo CLI. The Dojo CLI is a command line application used throughout development to run Dojo commands, the CLI can be installed via
npm globally or using
npx to run commands without the need for a global installation.
npm install @dojo/cli -g
Once the CLi has been installed, you can run
dojo on the command line to see what commands are available. Most commands need to be installed separately, the command to get started with Dojo is the
cli-create-app command, which creates a skeleton Dojo application to get you up and running quickly.
npm install @dojo/cli-create-app -g
Once the command is installed you can run
dojo create app --help to see all the options.
The template Dojo application
To create your Dojo application run (for the demo we will use
--tsx option to create an application using
dojo create app --name my-first-dojo-app --tsx
If you prefer to use
npx instead of globally installing dependencies globally you can run:
npx -p @dojo/cli-create-app -p @dojo/cli -- dojo create --name my-first-dojo-app --tsx
Once the command completes a brand new project will be created in the
my-first-dojo-app directory. The default template, includes a basic application with a header with routing setup.
To build and run your application for development, a npm script is pre-configured.
npm run dev
This builds the application using the
@dojo/cli-build-app command in
watch mode with the development server running, by default the port used is
9999 meaning your Dojo application can be access at http://localhost:9999.
Deploying your Dojo application to Vercel (formally Zeit)
When you've finished working (or just got started) on your application and want to shout about it to the world, there's no easier way to deploy a Dojo application than using Vercel's custom Dojo integration.
All that is needed is to have the vercel package installed globally,
npm install vercel -g. Once installed, running
vercel --prod in your application folder will deploy the built application to your Vercel account (once you have logged in).
Alternatively you can integrate your application's github (bitbucket and gitlab are supported too) repository by clicking
Import Project from the Vercel dashboard and now you will have a new deployment for pull requests and merges to master auto-magically.
Wrapping it up
Getting started with Dojo has never been easier! From creating your Dojo application to deploying the application into production with the Dojo CLI and excellent tooling available from Vercel, meaning that there has never been a better time to jump in and build your next project. Happy coding!
