Slide 75

Slide 75 text

THE TROUGH

Slide 76

Slide 76 text

5 THINGS THAT EMBER COULD DO BETTER

Slide 77

Slide 77 text

1. API CUSTOMIZATION 2. AUTHENTICATION 3. EXTERNAL jQUERY LIBRARIES 4. TESTING 5. INTEGRATION WITH EXISTING APPS

Slide 78

Slide 78 text

WITH GUIDANCE, THE TROUGH CAN EVEN BE FUN TO NAVIGATE

Slide 79

Slide 79 text

1. EMBER DATA API CUSTOMIZATION

Slide 80

Slide 80 text

MY API DOESN’T PLAY NICELY WITH EMBER DATA. EMBER GENERATE YOUR WAY OUT OF THAT ONE, SMART GUY.

Slide 81

Slide 81 text

OUR APP WANTS DATA FROM A NON-REST ENDPOINT

Slide 82

Slide 82 text

WHAT DO YOU DO WHEN YOUR API DOESN’T CONFORM?

Slide 83

Slide 83 text

SOLUTION 1 AJAX & pushPayload

Slide 84

Slide 84 text

store.pushPayload() Push any JSON (properly formatted) into the store, skipping Ember Data’s AJAX.

Slide 85

Slide 85 text

import Ember from 'ember';    export default Ember.Route.extend({  model: function() {  var store = this.store;  return Ember.$.getJSON("/user.json").then(function(response){  Ember.run(function() {  store.pushPayload("user", response);  });  return store.find("user", response.user.id);  });  }  }); USING PUSHPAYLOAD app/routes/application.js

ADD TO CART

Slide 88

Slide 88 text

ADD ITEM TO CART ISN’T WORKING

Slide 89

Slide 89 text

GOOD API DOCS: ESSENTIAL

Slide 90

Slide 90 text

SOLUTION 2 Custom Serializer/Adapter

Slide 91

Slide 91 text

ADAPTER: DEALS WITH THE SERVER SERIALIZER: DEALS WITH THE DATA

Slide 92

Slide 92 text

ADAPTERS & SERIALIZERS Your API Object({id: 3}).save() Adapter Builds URL, sends XHR Serializer Generates payload & parses response

Slide 93

Slide 93 text

CUSTOM ADAPTERS: WHEN YOU NEED TO MODIFY API ENDPOINTS

Slide 94

Slide 94 text

YES, THERE’S A GENERATOR FOR THAT

Slide 95

Slide 95 text

ember generate adapter cart-‐item

Slide 96

Slide 96 text

export default ApplicationAdapter.extend({  buildURL: function(type, id, record) {  var url = this._super(type, id, record); // MODIFY URL HERE :) return url;  }  }); USE buildURL TO MODIFY THE API ENDPOINT URL

Slide 97

Slide 97 text

export default ApplicationAdapter.extend({  buildURL: function(type, id, record) {  var url = this._super("item", id, record); var modifiedURL = "/cart" + url; return url;  }  }); OVERRIDE BUILDURL type is “cartItem” in the model… app/adapters/cart-item.js

Slide 98

Slide 98 text

export default ApplicationAdapter.extend({  buildURL: function(type, id, record) {  var url = this._super("item", id, record); var modifiedURL = "/cart" + url; return url;  }  }); OVERRIDE BUILDURL app/adapters/cart-item.js …so we’ll replace that with “item” for our API

Slide 99

Slide 99 text

export default ApplicationAdapter.extend({  buildURL: function(type, id, record) {  var url = this._super("item", id, record); var modifiedURL = "/cart" + url; return url;  }  }); OVERRIDE BUILDURL app/adapters/cart-item.js then preﬁx it with “cart” so it’s “/cart/items”

Slide 100

2. AUTHENTICATION

Slide 114

Slide 114 text

WHY THE HECK ISN’T AUTHENTICATION BUILT INTO EMBER?

Slide 115

Slide 115 text

signIn: function(email, password) {  Ember.$.post("/users/sign_in.json", {  user: {  email: email,  password: password  }  }, "json").then(function(response) {  this.store.pushPayload("user", response);  var user = this.store.getById("user", response.user.id);  this.send("signedIn", user);  this.send("closeModal");  }.bind(this));  }, ROLL YOUR OWN app/routes/application.js

signOut: function() {  Ember.$.ajax("/users/sign_out.json", {  method: "post",  dataType: "json",  data: {  _method: "DELETE"  }  }).then(function(response) {  this.store.pushPayload("user", response);  var user = this.store.getById("user", response.user.id);  this.set("controller.model", user);  this.send("closeModal");  }.bind(this));  } ROLL YOUR OWN app/routes/application.js
