ember-skill-tree exploration

This README outlines the details of collaborating on this Ember application.

Skill tree

Thoughts on how Ember (or anything) could be taught in order of importance. I would consider it a strike against the process anytime you have to say "don't worry about that right now." In theory - these things can roll out / giving the user a complete set of tools for increasingly ambitious application. (this assumes they are new to MVC - instead of porting over from another)

1. Install Ember

  • You may need to explain a bit about imports and exports. If they don't feel comfortable with NPM and imports and exports / don't just keep moving. Instead: initialize an npm project with them - and import and export some stuff between files to explain it clearly before moving on.

1.1

  • explain that Ember CLI is a tool that lets you create projects and files and that it watches your project for changes. Create a new project

2. Find a file to work in and clear out the confusing stuff

  • use a quick-find type command pallet to find the 'application.hbs' - and don't worry about the file structure yet.

  • explain that the 'application.hbs' is the 'root' for all templates. You can use the index.php or whatever experience they have to draw on. If you were going to do one thing - it would be there. This way - when they start their own practice projects / they'll get right where they need to be.

  • explain that .hbs is a different type of file than HTML. You will write standard HTML there - but you can also do a bunch of additional things as we'll outline in order of importance. These types of files are called "templates." handlebars/html-bars>hndlbrs>.hbs

  • address that there is an idea of a 'component' - and use the welcome page as an example. They'll ask "where is that code" - and you'll say... it's abstracted out into an 'addon' so, you don't see the code... and they'll be confused - so, you'll just have to say - "don't worry about that right now" (delete the welcome-page)

  • address that there is an 'outlet' sitting in your template - and that you'll use that later to describe where sub-routes should appear. They'll ask "what is a route" - and you'll have to say, "don't worry about that right now" (delete the outlet)

  • now we can do something.

3. Write some markup and styles

  • explain that the 'app.css' is the primary file for styles (by default) (this way - they can find it...)

  • write some decent markup examples to work with and some basic styles to ensure things are connecting

  • expose why you might want to start breaking up the style files - and why you might want a preprocessor

  • at this point - it's just like an HTML & CSS project (index.html and style.css) - so... why use Ember? At least the build pipeline auto-refreshes the page when you make changes to the files! : )

4. Use Ember

  • so far - you've used Ember CLI to create a project / and to watch for file changes and build your project (and display that in the browser) - but that's really just the tooling. We haven't worked with anything dynamic / or used Ember for what it's good at.

  • since we're working with a file called 'application' - you can create a 'controller' of the same name - and they can work together (describing this stuff here - as a precursor to components)

  • Use the CLI to generate a controller. ember generate controller application = "Hey, Ember. Please generate a controller and name it 'application'. thanks." (you could talk about how there is always a controller for everything... but that it's hidden to keep things clean / and that when you want to use it - you have to explicitly create the file which extends the bla bla... or save that for later...)

  • find that file with the command pallet (don't worry about file structure) - and explain that Embers conventions use naming to connect files. application.hbs - and application.js are linked by name. This will help dispell some of the 'magic.'

  • create a few properties in the controller and then use them in the template

5. Use Ember more

  • You can get a lot done with just one template and it's controller.

  • build out some fun stuff with inputs and buttons. maybe something of this complexity

  • (I'm late for real work - so, I'm not going to actually program the rest of this stuff)

6. Show how template/controller - is just like components

  • Take the functionality of the stuff you made - and break it out into a component instead of a controller.

7. from there...

  • depending on the person... and their goals - you might take a few paths. Maybe they should start getting some data from other sources... or maybe they should work with routes - and get some static pages.

  • my point... is that each step should leave the person capable. If you hook up a bunch of services and some models and some ember-data - and nested routes - and they don't understand how those things are helping them... then they are just memorizing things. At each stage - you need to hit the wall / where the tools can assist you. Some people are learning this flavor or MVC - but others are learning 'web applications' - and those people aren't just going to see parody here and there. They might have never heard or rails. They might have gone to a MEAN stack boot-camp and barely know HTML.

  • outlets might not be as important to understand as services - depending on what they want to build... but / having an about/contact page - might be a good example.

  • importing/using libraries

  • services (using them in components)

  • routing (links/outlets) (maybe file structure now - if at all)

  • using routes to get data

  • models (ember-data)

  • dynamic routing

  • state

  • testing

  • auth

  • creating addons

  • engines
