Vue-Surf
Very customized animated svg wave Vue component
Why ?
Current solutions for adding cool waves to websites are often less controllable. Many SVG Wave Generators generate random shapes, if you want to add animation, the randomness factor increases even more.
And the output is usually just image files. If you want to make changes later on, you'll need to regenerate them.
Install
npm install vue-surf
Usage
Add <VueSurf> component from vue-surf to your template, and Pass in at least two parameters, width and apexes to <VueSurf>.
<script setup>
import { VueSurf } from "vue-surf";
</script>
<template>
<VueSurf
:width="800"
:apexes="[[0, 50], [100, 0], [100, 50]]"
/>
</template>And Ta-da!
Props
width
width: {
type: [Number | String],
default: "100%"
}The width of the wave, accept direct number values representing pixels or string with px or % units."
color
type LinearGradientColor = {
name: string;
rotate?: number;
steps: {
offset: number;
color: string;
opacity?: number
}[];
}
color: {
type: [String, Object] as PropType<string | LinearGradientColor>,
default: "white",
}Configuring the fill color of the wave, it accept standard monochrome string or utilize a specific object format to configure linear gradients.
const color = reactive({
name: "myGradient" // name must be specified
rotate: 90,
steps: [
{ offset: 0, color: '#FEAC5E', opacity: 0.3 },
{ offset: 0.5, color: '#C779D0' },
{ offset: 1, color: '#4BC0C8' },
],
})
Radial gradients are currently not supported
shape
type WaveShape = "wavy" | "serrated" | "petal";
shape: {
type: String as () => WaveShape,
default: "wavy",
}In addition to the regular wave pattern, VueSurf also offer options for a serrated and a petal-like pattern for you to choose from.
apexesSeries
type Apex =
| [number | string, number | string]
| {
distance: number | string;
height: number | string;
};
type Apexes =
| Apex[]
| {
apexes: Apex[];
shape?: WaveShape;
color?: string | LinearGradientColor;
};
apexesSeries: {
type: Array as () => Apexes[],
default: undefined,
}What is Apex?
An apex is configured as the smallest unit of a wave, consisting of both distance and height. You can represent it using either an object or an array.
const apex = ref<Apex>([0, "50%"]); // [distance, height]
// or
const apex = ref<Apex>({ distance: 0, height: "50%" });Here, the term distance refers to the length of separation from the previous apex. And height denotes the vertical distance of the apex from the reference plane used for calculation.
Both distance and height accept direct number values representing pixels or string with px or % units.
⚠️ It is noteworthy that when configured using percentages, they will be calculated relative to the width of the wave.
What is Apexes?
Apexes are an array composed of multiple apex, and you can freely use either object or array formats for each apex within the array.
const apexes = ref<Apexes>([
{ distance: 0, height: "50%" },
[100, 50],
["100px", 120]
]);Additionally, if you wish to set apexes with shapes or colors distinct from the shape and color props, you can describe apexes using objects and specify the 'shape' and 'color' properties.
const myApexes = ref<Apexes>({
apexes: [
{ distance: 0, height: "20%" },
[100, 50],
["100px", 120]
],
shape: "petal",
color: "lightblue"
});
⚠️ Due to the absence of a preceding apex for the first apex, any distance configuration for it will be disregarded.
Setting ApexesSeries
ApexesSeries is an array composed of one or multiple apexes. Similarly, you have the option to utilize either object or array formats for apexes within it."
const apexesSeries = ref<Apexes[]>([
[
{ distance: 0, height: "20%" },
[120, 0],
[120, 120]
],
{
apexes: [
{ distance: 0, height: "10%" },
[120, 0],
[120, 60]
],
shape: "petal",
color: "lightblue"
}
])When you pass an ApexesSeries with a length greater than 1, the wave transformation animation will automatically activate. However, you can disable it by setting apexesSeriesTransformAuto to false.
Of course, you can also directly replace the values of ApexesSeries dynamically to achieve the transformation effect.
const apexesSeries = ref<Apexes[]>([
[
[0, 50],
[100, 0],
[100, 50]
],
])
apexesSeries.value = [
[0, 100],
[50, 0],
[50, 100]
]
⚠️ Please ensure that eachapexeswithin theapexesSeriespossesses an equal length and total distance to maintain the effectiveness of the transformation animation."
apexesIndex
apexesIndex: {
type: Number,
default: undefined,
}You can specify apexesIndex to determine which set of apexes from apexesSeries the wave should display.When it is configured, the transformation animation will be deactivated.
side
type WaveSide = "top" | "bottom";
side: {
type: String as () => WaveSide,
default: "top",
}The determination of whether the wave faces upwards or downwards also dictates whether the height of the apexes is measured from the top or the bottom.
<template>
<section />
<VueSurf
:width="800"
:side="'top'"
:apexes="[[0, 50], [100, 0], [100, 50]]"
/>
</template>
<template>
<VueSurf
:width="800"
:side="'bottom'"
:apexes="[[0, 50], [100, 0], [100, 50]]"
/>
<section />
</template>
repeat
repeat: {
type: Boolean,
default: true,
}The decision to automatically repeat is contingent upon whether the cumulative distance set by an apexes is insufficient to cover the entire width of the wave.
<template>
<section />
<VueSurf
:width="800"
:apexes="[[0, 50], [100, 0], [100, 50]]"
:repeat="false"
/>
</template>
closure
closure: {
type: Boolean,
default: true,
}To facilitate a natural alignment of repeated waves, the height of the last apex in an apexes will automatically align with the height of the first apex. You can set it to false to disable this behavior.
<template>
<section />
<VueSurf
:width="800"
:apexes="[[0, 50], [100, 0], [100, 100]]" // higher then first apex
:closure="false"
/>
</template>
smooth
smooth: {
type: [Boolean, Number],
default: true,
}At times, when you configure a significant difference in distance between consecutive apexes, the presentation of the wave may not appear as smooth.
To mitigate such outcomes, we perform certain calculations. However, you have the option to set it to false to disable this behavior.
Alternatively, you can provide a number value between 0 and 1 to adjust the level of smoothness.
<template>
<section />
<VueSurf
:width="800"
:apexes="[
[0, 50],
[100, 0],
[50, 100],
[200, 0],
[100, 50]
]"
:smooth="false"
/>
</template>
⚠️ If the numerical disparities are indeed substantial, the extent of smoothing may still remain limited
marquee
marquee: {
type: Boolean,
default: true,
}When you use , the marquee animation effect will automatically activate. You can set it to false to deactivate the animation.
Switch it from true to false, the animation will completely reset. If you only wish to pause the marquee, please set marqueeSpeed to zero.
marqueeSpeed
marqueeSpeed: {
type: Number,
default: 2,
}It accepts a number value ranging from -25 to 25 to control the speed of the marquee animation. When the value is greater than 0, the animation moves to the right; when less than 0, it moves to the left.
transitionDuration
transitionDuration: {
type: Number,
default: 500,
}Regardless of how you modify the current state of the wave ( ApexesSeriesTransform, Changing ApexesIndex or Changing Apex Value Directly... ), there will always be interpolation animations. You can pass a number value to adjust the transition duration. The unit is millisecond.
apexesSeriesTransformAuto
apexesSeriesTransformAuto: {
type: Boolean,
default: true,
}When you pass an ApexesSeries with a length greater than 1, VueSurf will transform the wave in accordance with the order of the ApexesSeries. You can set apexesSeriesTransformAuto to false to disable it.
apexesSeriesTransformDuration
apexesSeriesTransformDuration: {
type: Number,
default: undefined,
}This parameter only becomes meaningful when apexesSeriesTransformAuto is set to true.
It determines how long it takes to replace the current wave with the next set of Apexes. The unit is millisecond.
To achieve a seamless animation effect, when no value is specified, it defaults to being the same as transitionDuration. However, if transitionDuration is set to 0, apexesSeriesTransformDuration will automatically be set to 500.
onApexesChanged
type ApexesChangedCallback = (
currentApexes: Apex[],
currentShape: WaveShape,
) => void;
onApexesChanged: {
type: Function as ApexesChangedCallback,
default: undefined,
}A callback function that is invoked when there is an update to the apexes.
