Introducing our Angular 10 CRUD Application
We will learn how to build an Angular 10 front-end application that fetches data from a REST API of products:
- Each product has id, name, description, availability status.
- Users would be able to create, retrieve, update, and delete products.
- Users can search for products by name.
The REST API Endpoints
We’ll be building an Angular 10 frontend app for a presumed REST API exporting the following REST API endpoints:
- POST /api/products create new product
- GET /api/products retrieve all products
- GET /api/products/:id retrieve a product by
:id - PUT /api/products/:id update a product by
:id - DELETE /api/products/:id delete a product by
:id - DELETE /api/products delete all products
- GET /api/products?name=[keyword] find all products which name contains the passed
keyword.
All of them can work well with this Angular App.
Angular 10 CRUD App Structure
These are the components of our CRUD app:
- The
Appcomponent is the parent of all other components and contains arouter-outletdirective where the router will be inserting any matched component. It also contains a navigation bar that contains links to the app routes usingrouterLinkdirective.
– ProductListComponent which displays the list of products.
– ProductUpdateComponent which displays a form for editing product’s details by :id.
– ProductCreateComponent which displays a form for creating a new product.
The components use the ProductService methods for actually making CRUD operations against the REST API. The service makes use of Angular 10 HTTPClient to send HTTP requests to the REST and process responses.
