An opinionated starter template based on the Rollup Sapper template. 🚀
The purpose of this repo was to save me time by doing all of the things I do on every Sapper project, but hey you might find it useful too right?!
To clone it and get started:
# for Rollup
npx degit matt3224/sapper-start my-app
cd my-app
npm install
npm run dev
Open up localhost:3000 and start clicking around.
Consult sapper.svelte.dev for help getting started with Sapper itself.
If you use this a lot you can alias it by putting this in your zshrc or bashrc:
alias sapper-start='npx degit https://github.com/matt3224/sapper-start .'
Then simply cd into your empty project directory and run sapper-start
Good question, I found myself doing these changes on every project and thought I'd save myself and you some time by making a little repo you could import just like the official sapper-template.
Here are the differences:
numworker: 1
in rollup.config to prevent crash on servers with a single processor core~
& auto resolves .js, .mjs, .html, .svelte, .scssimport { util } from '~/utils';
instead of import { util } from '../../utils.js';
If you run into an issue which you don't see in the normal sapper-template, open an issue.

If you are coming from the background of working with angularjs, it was quite straight forward to access and manipulate the DOM there. You had access to the DOM node through element
injected in the link
function of the directive.
function link(scope, element, attrs) {
}
Or through angular.element
which was an AngularJS’s built in subset of jQuery. But this approach had its drawbacks. It made your code tightly coupled with Browser’s API.
The new Angular (2 onwards) works on multiple platforms: mobile, web workers etc. So, they have introduced a number of APIs to work as an abstraction layer between your code and platform APIs. These APIs come in the form of different reference types likeElementRef
, TemplateRef
, ViewRef
, ComponentRef
and ViewContainerRef
.
In this blog, we will see some examples of how these reference types can be used to manipulate DOM in angular. But before that let’s look at the ways to access these reference types within a Component/Directive.
DOM Queries
Angular has provided two ways to query/access various reference types within a Component/Directive. These are
These are decorators which can be used within a Component/Directive as @ViewChild
(returns a single reference) or @ViewChildren
(returns a list of references in the form of a QueryList
). These will assign the values of reference types from template to the component fields they are applied to. The basic usage is as follow:
@ViewChild(selector, {read: ReferenceType}) fieldName;
A selector can be a string representing a template reference variable, or a Component/Directive class, or a TemplateRef or a provider defined in the child component tree.
@ViewChild("myElem") template: ElementRef;
The second parameter is optional and is only required to query some reference types which can’t be inferred easily by Angular like ViewContainerRef
.
@ViewChild("myContainer", {read: ViewContainerRef}) container: ViewContainerRef;
The usage is pretty much similar to that of ViewChild/ViewChildren. The only difference is that it queries within the <ng-content>
projected elements of the component while the @ViewChild
queries within the template of the component. This will be explained better in the examples of upcoming sections.
DOM access via ElementRef
ElementRef
is a very basic abstraction layer on a DOM element in Angular. It’s an angular wrapper around the native element.
You can get hold of ElementRef in a Component or Directive in following ways:
Host element of a Component or Directive can be accessed via direct DI in the constructor.
@Component({
selector: 'app-test',
template: '<div>I am a test component</div>'
})
export class TestComponent implements OnInit {
constructor(private element: ElementRef) { }
ngOnInit() {
console.log(this.element.nativeElement);
}
}
/*
* Output:
* <app-test>
* <div>I am a test component</div>
* </app-test>
* */
@Component({
selector: 'app-test',
template: `
<div #child1>First Child</div>
<div>Second Child</div>
`
})
export class TestComponent implements OnInit {
@ViewChild("child1") firstChild: ElementRef;
constructor() { }
ngOnInit() {
console.log(this.firstChild.nativeElement);
}
}
/*
* Output: <div>First Child</div>
* */
Works in a similar manner as that of @ViewChild
, but for <ng-content>
projected elements.
// Child Component
@Component({
selector: "component-a",
template: `<ng-content></ng-content>`
})
export class ComponentA {
@ContentChild("contentChild") contentChild: ElementRef;
ngOnInit() {
console.log(this.contentChild.nativeElement);
}
}
// Parent Component
@Component({
selector: 'app-test',
template: `
<component-a>
<div #contentChild>Content Child 1</div>
<div>Content Child 2</div>
</component-a>
`
})
export class TestComponent implements OnInit {}
/*
* Output: <div>Content Child 1</div>
* */
It looks pretty straight forward that you can easily access a DOM element via ElementRef
and then manipulate the DOM by accessing the nativeElement
. Something like this:
@Component({
selector: 'app-test-component',
template: `
<div class="header">I am a header</div>
<div class="body" #body>
</div>
<div class="footer">I am a footer</div>
`
})
export class TestComponent implements AfterContentInit {
@ViewChild("body") bodyElem: ElementRef;
ngAfterContentInit(): void {
this.bodyElem.nativeElement.innerHTML = `<div>Hi, I am child added by directly calling the native APIs.</div>`;
}
}
However, the direct usage of ElementRef is discouraged by Angular Team because it directly provides the access to DOM which can make your application vulnerable to XSS attacks. It also creates tight coupling between your application and rendering layers which makes is difficult to run an app on multiple platforms.
Everything is a ‘View’ in Angular
A view is the smallest building block of an angular app’s UI. Every component has its own view. You can consider it as a group of elements which can be created and destroyed together.
A view can be classified into two types:
Displaying a view in UI can be broken down into two steps:
Embedded Views
Embedded views are created from templates defined using <ng-template>
element.
First a template needs to be accessed within a component as TemplateRef
using @ViewChild
and template reference variable. Then, an embedded view can be created from a TemplateRef
by passing a data-binding context.
const viewRef = this.template.createEmbeddedView({
name: "View 1"
});
This context is being consumed by the template in<ng-template>
.
<ng-template #template let-viewName="name">
<div>Hi, My name is {{viewName}}. I am a view created from a template</div>
</ng-template>
You can also use the $implicit
property in the context if you have only a single property to bind.
const viewRef = this.template.createEmbeddedView({
$implicit: "View 1"
});
In this case, you can skip assigning values to template variables.
<ng-template #template let-viewName>
<div>Hi, My name is {{viewName}}. I am a view created from a template</div>
</ng-template>
Till now, we have created only an instance of ViewRef
. This view is still not visible in the UI. In order to see it in the UI, we need a placeholder (a view container) to render it. This placeholder is being provided by ViewContainerRef
.
Any element can serve as a view container, however <ng-container>
is a better candidate as it is rendered as a comment and doesn’t leave any redundant element in the html DOM.
@Component({
selector: 'app-test-component',
template: `
<div class="header">I am a header</div>
<div class="body">
<ng-container #container></ng-container>
</div>
<div class="footer">I am a footer</div>
<ng-template #template let-viewName="name">
<div>Hi, My name is {{viewName}}. I am a view created from a template</div>
</ng-template>
`,
})
export class TestComponent implements AfterContentInit {
@ViewChild("template") template: TemplateRef;
@ViewChild("container", {read: ViewContainerRef}) container: ViewContainerRef;
constructor() { }
ngAfterContentInit(): void {
const viewRef = this.template.createEmbeddedView({
name: "View 1"
});
this.container.insert(viewRef);
}
}
Both <ng-container>
and <ng-template>
elements will be rendered as comments leaving the html DOM neat and clean.
The above 2 steps process of creating a view and adding it into a container can further be reduced by using the createEmbeddedView
method available in the ViewContainerRef
itself.
this.container.createEmbeddedView(this.template, {
name: "View 1"
});
This can be further simplified by moving the whole view creation logic from component class to the template using ngTemplateOutlet
and ngTemplateOutletContext
.
@Component({
selector: 'app-test-component',
template: `
<div class="header">I am a header</div>
<div class="body">
<ng-container [ngTemplateOutlet]="template" [ngTemplateOutletContext]="{name: 'View 1'}"></ng-container>
</div>
<div class="footer">I am a footer</div>
<ng-template #template let-viewName="name">
<div>Hi, My name is {{viewName}}. I am a view created from a template</div>
</ng-template>
`
})
export class TestComponent {}
Host Views
Host Views are quite similar to Embedded View. The only difference is that the Host Views are created from components instead of templates.
In order to create a host view, first you need to create a ComponentFactory
of the component you want to render using ComponentFactoryResolver
.
constructor(
private componentFactoryResolver: ComponentFactoryResolver
) {
this.someComponentFactory = this.componentFactoryResolver.resolveComponentFactory(SomeComponent);
}
Then, a dynamic instance of the component is created by passing an Injector
instance to the factory. Every component should be bound to an instance of Injector
. You can use the injector of the parent component for the dynamically created components.
const componentRef = this.someComponentFactory.create(this.injector);
const viewRef = componentRef.hostView;
Rendering a host view is almost similar to rendering an embedded view. You can directly insert it into a view container.
@Component({
selector: 'app-test-component',
template: `
<div class="header">I am a header</div>
<div class="body">
<ng-container #container></ng-container>
</div>
<div class="footer">I am a footer</div>
`,
})
export class TestComponentComponent implements AfterContentInit {
@ViewChild("container", {read: ViewContainerRef}) container: ViewContainerRef;
private someComponentFactory: ComponentFactory<SomeComponent>;
constructor(
private componentFactoryResolver: ComponentFactoryResolver,
private injector: Injector
) {
this.someComponentFactory = this.componentFactoryResolver.resolveComponentFactory(SomeComponent);
}
ngAfterContentInit(): void {
const componentRef = this.someComponentFactory.create(this.injector);
const viewRef = componentRef.hostView;
this.container.insert(viewRef);
}
}
Or by directly calling the createComponent
method of ViewContainerRef
and passing the component factory instance.
this.container.createComponent(this.someComponentFactory);
Now, similar to embedded view, we can also shift the whole logic of host view creation in template itself using ngComponentOutlet
.
@Component({
selector: 'app-test-component',
template: `
<div class="header">I am a header</div>
<div class="body">
<ng-container [ngComponentOutlet]="comp"></ng-container>
</div>
<div class="footer">I am a footer</div>
`
})
export class TestComponent {
comp = SomeComponent;
}
Don’t forget to store the reference of the component class in parent component’s field. The template has access only to the fields of the components.
Here we come to an end. Let’s conclude what we have understood till now.
ElementRef
, TemplateRef
, ViewRef
, ComponentRef
and ViewContainerRef
.@ViewChild
and @ContentChild
.ElementRef
. However, manipulating this element directly is discouraged because of security reasons.So, that’s it for today about understanding DOM manipulation in Angular.

Are you leading an organization that has a large campus, e.g., a large university? You are probably thinking of introducing an electric scooter/bicycle fleet on the campus, and why wouldn’t you?
Introducing micro-mobility in your campus with the help of such a fleet would help the people on the campus significantly. People would save money since they don’t need to use a car for a short distance. Your campus will see a drastic reduction in congestion, moreover, its carbon footprint will reduce.
Micro-mobility is relatively new though and you would need help. You would need to select an appropriate fleet of vehicles. The people on your campus would need to find electric scooters or electric bikes for commuting, and you need to provide a solution for this.
To be more specific, you need a short-term electric bike rental app. With such an app, you will be able to easily offer micro-mobility to the people on the campus. We at Devathon have built Autorent exactly for this.
What does Autorent do and how can it help you? How does it enable you to introduce micro-mobility on your campus? We explain these in this article, however, we will touch upon a few basics first.
You are probably thinking about micro-mobility relatively recently, aren’t you? A few relevant insights about it could help you to better appreciate its importance.
Micro-mobility is a new trend in transportation, and it uses vehicles that are considerably smaller than cars. Electric scooters (e-scooters) and electric bikes (e-bikes) are the most popular forms of micro-mobility, however, there are also e-unicycles and e-skateboards.
You might have already seen e-scooters, which are kick scooters that come with a motor. Thanks to its motor, an e-scooter can achieve a speed of up to 20 km/h. On the other hand, e-bikes are popular in China and Japan, and they come with a motor, and you can reach a speed of 40 km/h.
You obviously can’t use these vehicles for very long commutes, however, what if you need to travel a short distance? Even if you have a reasonable public transport facility in the city, it might not cover the route you need to take. Take the example of a large university campus. Such a campus is often at a considerable distance from the central business district of the city where it’s located. While public transport facilities may serve the central business district, they wouldn’t serve this large campus. Currently, many people drive their cars even for short distances.
As you know, that brings its own set of challenges. Vehicular traffic adds significantly to pollution, moreover, finding a parking spot can be hard in crowded urban districts.
Well, you can reduce your carbon footprint if you use an electric car. However, electric cars are still new, and many countries are still building the necessary infrastructure for them. Your large campus might not have the necessary infrastructure for them either. Presently, electric cars don’t represent a viable option in most geographies.
As a result, you need to buy and maintain a car even if your commute is short. In addition to dealing with parking problems, you need to spend significantly on your car.
All of these factors have combined to make people sit up and think seriously about cars. Many people are now seriously considering whether a car is really the best option even if they have to commute only a short distance.
This is where micro-mobility enters the picture. When you commute a short distance regularly, e-scooters or e-bikes are viable options. You limit your carbon footprints and you cut costs!
Businesses have seen this shift in thinking, and e-scooter companies like Lime and Bird have entered this field in a big way. They let you rent e-scooters by the minute. On the other hand, start-ups like Jump and Lyft have entered the e-bike market.
Think of your campus now! The people there might need to travel short distances within the campus, and e-scooters can really help them.
What advantages can you get from micro-mobility? Let’s take a deeper look into this question.
Micro-mobility can offer several advantages to the people on your campus, e.g.:

The electric scooter revolution has caught on super-fast taking many cities across the globe by storm. eScooters, a renovated version of old-school scooters now turned into electric vehicles are an environmentally friendly solution to current on-demand commute problems. They work on engines, like cars, enabling short traveling distances without hassle. The result is that these groundbreaking electric machines can now provide faster transport for less — cheaper than Uber and faster than Metro.
Since they are durable, fast, easy to operate and maintain, and are more convenient to park compared to four-wheelers, the eScooters trend has and continues to spike interest as a promising growth area. Several companies and universities are increasingly setting up shop to provide eScooter services realizing a would-be profitable business model and a ready customer base that is university students or residents in need of faster and cheap travel going about their business in school, town, and other surrounding areas.
In many countries including the U.S., Canada, Mexico, U.K., Germany, France, China, Japan, India, Brazil and Mexico and more, a growing number of eScooter users both locals and tourists can now be seen effortlessly passing lines of drivers stuck in the endless and unmoving traffic.
A recent report by McKinsey revealed that the E-Scooter industry will be worth― $200 billion to $300 billion in the United States, $100 billion to $150 billion in Europe, and $30 billion to $50 billion in China in 2030. The e-Scooter revenue model will also spike and is projected to rise by more than 20% amounting to approximately $5 billion.
And, with a necessity to move people away from high carbon prints, traffic and congestion issues brought about by car-centric transport systems in cities, more and more city planners are developing more bike/scooter lanes and adopting zero-emission plans. This is the force behind the booming electric scooter market and the numbers will only go higher and higher.
Companies that have taken advantage of the growing eScooter trend develop an appthat allows them to provide efficient eScooter services. Such an app enables them to be able to locate bike pick-up and drop points through fully integrated google maps.
It’s clear that e scooters will increasingly become more common and the e-scooter business model will continue to grab the attention of manufacturers, investors, entrepreneurs. All this should go ahead with a quest to know what are some of the best electric bikes in the market especially for anyone who would want to get started in the electric bikes/scooters rental business.
We have done a comprehensive list of the best electric bikes! Each bike has been reviewed in depth and includes a full list of specs and a photo.
