Welcome to final part of the recipe book app. We will HTTP requests in our app, in this part.

We will add on top of the app we have create in the previous part. You can find the code for the earlier part in this github link.

We will add functionalities of Save Data and Fetch Data from Firebase database in our project.

Save Data

We need to setup a new Project in firebase. The steps are exactly same as mentioned in the Angular Basics-12 post. We will follow them and create a new project named angular-recipe-book and it will use the Realtime Database.

Realtime database

First add the HttpClientModule in app.module.ts file.

app.module.ts

Now, we will create a new service called data-storage.service.ts in shared folder. Here we will use the HttpClient and RecipeService and putting all the recipies in our firebase endpoint.

Also notice that we have added recipes.json at the end of our firebase endpoint.

data-storage.service.ts

Now, we will add a function onSaveData to the click handler in header.component.html file.

header.component.html

Next, in the header.component.ts file we are implementing the onSaveData function by calling the storeRecipes from dataStorageService service.

header.component.ts

Now, just click on the Save Data button and our data will be stored in the firebase database.

Save Data

Now, it’s time to fetch the data. We need to create a new recipe service for it first in recipe.service.ts file. We are also commenting out the hardcoded recipes.

recipe.service.ts

Now, we will add the function fetchRecipes in data-storage.service.ts file. Here, we are just using the GET request to get all data.

data-storage.service.ts

Next, we will add a function onFetchData() click handler in header.component.html file.

header.component.html

Now, just add the function onFetchData() in header.component.ts file.

header.component.ts

Now, our Fetch and Save are working properly and taking data from stored firebase database.

Working

It’s time to deploy our application, as it’s finally complete. For this we will first run the below command in our project.
