Preparing the environment

Creating the Firestore Project

1. Go to console.firebase.com and login if necessary
2. create a new project called "code-mentoring-edition1".
3. Once inside the project, click on the "Project Overview" button on the top-left
4. click on the "Add App" button, just bellow the name of your project (code-mentoring-edition1).
5. Amongst the icons, choose "Web" (the last one)
6. When asked for it, also call the app "code-mentoring-edition1"
7. check the box for Hosting, and set the url to whatever you wish.
8. click the "Register the App" button and finish the process clicking on "next" and "continue to console"
9. back to the console, in "Project Overview", click on the newly created app icon,below the project name and on the gear icon (settings)
10. Once in the project settings, scroll down to the app settings and from the "Automatic", "CDN", "Config", choose "Config"
11. Copy the snippet and paste in somewhere, we're going to use it later on.

Creating the Angular Project

if you haven't followed along during last session, those are the steps to take to create the project:

1. open a terminal in the directory you want your project to be located in.
2. run ng new code-mentoring-edition1 --routing --style sccs
3. Once the process is done, run cd code-mentoring-edition1, then run code . to open the project in VSCode.
4. Open VSCode terminal (View/Terminal) and inside it, run ng add @angular/fire. It might ask you for authentication & permissions. When asked, choose the code-mentoring-edition1 project from the list.
5. run npm i @types/firebase --save-dev to install the types for firebase as a development dependency.
6. in the app folder, create the following directories:
   • core
   • shared
   • sections
7. in the core folder, create the following directories:
   • models
   • pipes
   • services
   • guards
8. in the shared folder, create a services directory

Configuring the angular project

1. in the tsconfig.json file, add the the following snippet in the compilerOptions:

    "strictNullChecks": false,
        "paths": {
        "@env": ["src/environments/environment"],
        "@shared/*": ["src/app/shared/*"],
        "@core/*": ["src/app/core/*"],
        "@sections/*": ["src/app/sections/*"]
    },
    "resolveJsonModule": true,
    "allowSyntheticDefaultImports": true,
    "typeRoots": ["node_modules/@types"],
   

2. In the root folder of the project, if it doesn't exist, create a file named .editorconfig (starting with a dot). In that file,

   1. under [*], add the following configs:

      quote_type = single
      max_line_length = 140
      

   2. under [*.ts], add strictNullCheck = false

3. in the tslint.json file, change rules.variable-name to :

    "options": [
       "allow-leading-underscore",
       "allow-pascal-case",
       "ban-keywords",
       "check-format",
       "require-const-for-all-caps"
     ]
   

4. in the environment.ts file, add the firebaseConfig object we got from the firestore console, to the environment constant.

5. Also add a variable called collections than holds firestore collections names (venues,users, checksIn). Once done, the environment constant should look like this:

       export const environment = {
           production: false,
           firebaseConfig: {
               apiKey: 'XXXXXXXXXXXXXXXXXXXXXXXXX',
               authDomain: '??????????',
               projectId: 'code-mentoring-edition1',
               storageBucket: 'code-mentoring-edition1.appspot.com',
               messagingSenderId: 'XXXXXXXXX',
               appId: 'XXXXXXXXXXXXXXXXXXX',
               measurementId: 'XXXXXXXXXXXXXXXXxxx',
           },
           collections: {
               venues: 'venues',
               users: 'users',
               checksIn: 'checksIn',
           },
       };
   

6. Repeat the 2 previous points for the environment.prod.ts file

Starting to code

Core Module

1. create the core module: ng g m core
2. inside core.module.ts, define a constant array called module and add the necessary modules, like this

   const modules = [AngularFireAuthModule, AngularFirestoreModule];
   

3. in the imports array of the decorator @NgModule add the following:
   1. CommonModule
   2. ...modules
   3. AngularFireModule.initializeApp(environment.firebaseConfig)
4. in the exports array, add the following:
   1. ...modules
5. in the providers array, add the following:
   1. AngularFirestore
   2. AuthService
6. in the constructor of the module, add the following line:

   constructor() {
       firebase.setLogLevel('info');
   }
   

users service

1. create the service using ng g s core/services/users
2. add the AngularFireStore provider using dependency injection:
3. add the UsersService to the providers of the core.module.ts file

auth Service

1. create the service using ng g s core/services/auth
2. add the AngularFireAuth provider using dependency injection: constructor(protected _afAuth: AngularFireAuth) {}
3. add the AuthService to the providers of the core.module.ts file
