How to add dynamic styles with variables with Vue.js?

To add dynamic styles with variables with Vue.js, we can use the style prop.

For instance, we write

<template>
  <img src="/img.jpg" alt="" :style="{ 'background-color': backgroundColor }" />
</template>

to set the background-color of the image to backgroundColor where backgroundColor is a reactive property.

Sometimes, we want to apply global variables to Vue.js.

In this article, we’ll look at how to apply global variables to Vue.js.

How to apply global variables to Vue.js?

To apply global variables to Vue.js, we can add our global variables into the Vue prototype.

For instance, we write

Vue.prototype.$appName = 'App'

to add the $appName global variable that we can access in all components in the app with

this.$appName

Conclusion

To apply global variables to Vue.js, we can add our global variables into the Vue prototype.

Sometimes, we want to pass props with programmatic navigation Vue.js.

In this article, we’ll look at how to pass props with programmatic navigation Vue.js.

How to pass props with programmatic navigation Vue.js?

To pass props with programmatic navigation Vue.js, we call $router.push with an object with the params property with the props we want to pass into a component.

Then when we define the route, we set the props property to true to let us take the route parameters in as props into the route component.

For instance, we write

this.$router.push({ name: "foo", params: { title: "test title" } });

to call $router.push to navigate to the route with the given name.

The params object will be passed in as props.

Then we write

{
  path: "/foo",
  name: "foo",
  component: FooComponent,
  props: true
}

in the routes array that we use to create the VueRouter instance to add the route with name 'foo' and we set props to true to make the params available as props on FooComponent.

Conclusion

To pass props with programmatic navigation Vue.js, we call $router.push with an object with the params property with the props we want to pass into a component.

Then when we define the route, we set the props property to true to let us take the route parameters in as props into the route component.

Sometimes, we want to load external templates in Vue.js components.

In this article, we’ll look at how to load external templates in Vue.js components.

How to load external templates in Vue.js components?

To load external templates in Vue.js components, we can use the httpVueLoader in Vue 2 and Vue.defineAsyncComponent method in Vue 3.

For instance, we write

new Vue({
  components: {
    "my-component": httpVueLoader("MyComponent.vue"),
  },
});

to register the my-component component by calling httpVueLoader with the Vue component path in Vue 2.

And in Vue 3, we write

Vue.createApp({
  components: {
    "my-component": Vue.defineAsyncComponent(() =>
      loadModule("./MyComponent.vue", opts)
    ),
  },
});

to register my-component by assigning it to the component object that’s returned with Vue.defineAsyncComponent.

Conclusion

To load external templates in Vue.js components, we can use the httpVueLoader in Vue 2 and Vue.defineAsyncComponent method in Vue 3.

Sometimes, we want to use Vuetify tabs with Vue Router.

In this article, we’ll look at how to use Vuetify tabs with Vue Router.

How to use Vuetify tabs with Vue Router?

To use Vuetify tabs with Vue Router, we can set the to prop of the v-tab component to a Vue Router route path.

For instance, we write

<template>
  <v-tabs v-model="activeTab">
    <v-tab v-for="tab in tabs" :key="tab.id" :to="tab.route" exact>
      {{ tab.name }}
    </v-tab>
  </v-tabs>
</template>

to set the to prop of each v-tab component to tab.route where tab.route is the path to a page as we defined in the routes array when we created the VueRouter instance.

Conclusion

To use Vuetify tabs with Vue Router, we can set the to prop of the v-tab component to a Vue Router route path.
