What to do if the svg part is not displayed in vue

Introduction

Vue.js has become one of the most popular front-end frameworks. It is easy to learn and use, efficient and flexible, and can quickly develop single page applications (SPA). Vue.js also implements a series of excellent functions such as data binding and component architecture through its "responsive" design mode. This article will discuss how to solve the problem when SVG images cannot be displayed properly in Vue.js.

Problem description

In Vue.js, when using SVG images, you may encounter the following problems:

1. The image cannot be displayed
2. When you view the same SVG image on different devices, different effects are displayed

How to solve it?

1. Check the SVG image

In Vue.js, when the SVG image cannot be displayed normally, you must first check the code of the SVG image. Here you need to verify the following:

· The image code is correct.
· Is the size of the image correct? If the size of the SVG image is 0, the image cannot be displayed.
· Whether the image overlaps other components. If the SVG image overlaps another component, it may cause the image to not display properly.

2. Using Vue.js plugin

If your SVG image is not the correct size, you can use the Vue.js plugin to resize it. Here are some plugins to help you resize SVG images and make them display properly:

vue-svg-loader: This plugin converts SVG images into Vue.js components so you can use them directly in your code SVG markup. Using this plug-in, you can better control and adjust the size and color of SVG images, and you can also avoid flickering problems caused by using SVG images.

Vue-SVGicon: This plugin provides a way to use SVG images as icons. You can use it to reference SVG images through Vue.js components.

Vue-SVG-inline: This plugin provides a way to convert SVG images to inline SVG.

You can use these plug-ins to make SVG images display normally in Vue.js, and at the same time, you can better control the size and color of SVG images.

3. Optimize SVG images

If problems occur when using SVG images in Vue.js, you can optimize the code of the SVG image to better adapt to Vue.js componentized design.

· Use one SVG symbol for all SVG images. This reduces requests while also providing a way to reference the SVG image's code as a symbol, making it easier to extend and maintain.
· Remove unnecessary SVG elements and attributes. This can reduce the size of the SVG file and speed up loading.
· Avoid using SVG’s inline style. In Vue.js, SVG images can be styled using classes and selectors in CSS files, which gives you greater control over the style of SVG.

Conclusion

When using SVG images in Vue.js, you may encounter some problems. These issues can be caused by incorrect coding, size, color, and overlapping of SVG images. You can use the Vue.js plugin to resize SVG images and make them display properly. You can also optimize the SVG image code to adapt to the component-based design of Vue.js. Through these methods, you can make SVG images better for use in Vue.js.
