Get started with Angular Grid in 5 minutes – ag-Grid – Medium

Integration
ag-Grid and its Angular grid component can be easily integrated into any Angular project bundler setup. component.html in your favorite text editor and add the ag-grid-angular component to the markup:
ag-grid-angular
style="width: 500px; height: 500px;"
class="ag-theme-balham"
[rowData]="rowData"
[columnDefs]="columnDefs"

/ag-grid-angularThe HTML above includes a wrapper DIV element which sets the grid dimensions and specifies the grid's theme by setting the className to ag-theme-balham. Angular Grid Sorting
Enabling sorting in ag-Grid is actually quite simple — all you need to do is set the enableSorting property to true on the ag-grid-angular component:
ag-grid-angular
[enableSorting]="true"
[rowData]="rowData"
the property is added, you should be able to sort the grid by clicking on the column headers. Angular Grid Filtering
As with sorting, enabling filtering is as easy as setting the enableFilter property to true:
ag-grid-angular
[enableFilter]="true"
[rowData]="rowData"
this property is set, the grid will display a small column menu icon when you hover over the header. Angular Grid Pagination
To enable pagination in our Angular grid, all you need to do is set the pagination property to true on the ag-grid-angular component:
ag-grid-angular
[pagination]="true"
[rowData]="rowData"
adding the property, you should be able to move through the pages by using the controls at the bottom of the grid:
By default the grid uses a page size of 100 records, but it can easily be changed through configuration options. Continue reading


How to Handle Errors Globally in Angular – The Info Grid

In this post, I will show you how to intercept the default error handler, and then send the errors to a remote logging service (Simple REST API call) and show a friendly message to the user. Then, we need to add an handleError method in our class, which will catch the errors in our app and do something with the errors. One option would be sending it to a remote logging server such as AWS Cloud Watch and provide a custom error message to the user. To do this, we need to create a logger service and inject it to our custom error handler class. Now, our complete class should look like this now:

Our logger service will look something like this:

NB: Please note, that am sending the error as the body. Continue reading


Building maintainable Angular applications – Versett – Medium

Presentational and Container Components
One similarity between React, or other component based libraries, and Angular is presentational and container components–the idea of splitting the view and the logic into their own separate components instead of combining them into one. Instead of performing logic within the presentational component, the presenters use the @Output() feature of Angular to let the container decide how to handle events. Dan Abramov has an excellent article on presentational and container components, which refers to React, but the same principles apply to Angular. The separation of streams and data is a very effective way to remove coupling between the presentational and container components. It was only after we had added ngrx to our projects and embraced the pattern that we understood the original motivations of the Angular team, and how RxJS could help keep our code maintainable.

ngFor in Angular 5 Instead of ngRepeat

As we have seen in AngularJS to repeat the loop, we have to use the angular’s directive named as . As the new Angular 5 feature comes with the same functionality but its directive is named as . For previous AngularJS version we have to simply just import or linked the library in the project, but now the Angular 5 (TypeScript) has its requirements such NodeJS and Git Version Control (optional), Can be used from windows command prompt. on running the this will open up a pre build component of Angular Documentation

After installation, let’s create a component for any view but the scope of this tutorial was to learn about ngFor

Check out what are components? In AngularJS to display the data from an array as a list, we would use the directive, In Angular 5 we have the directive. Continue reading
