How do I import svg from file to a component in angular 5?

问题

All tutorials with adding svg to a component in AngularCli that I found recommend to insert it in html template, something like this:

<div>
  <svg viewBox="0 0 250 250">
    <svg:g class="group">
       <svg:polygon class="shield" points="125,30 125,30 125,30 31.9,63.2 46.1,186.3 125,230 125,230 125,230 203.9,186.3 218.1,63.2" />
       <svg:path class="a" d="M125,52.1L66.8,182.6h0h21.7h0l11.7-29.2h49.4l11.7,29.2h0h21.7h0L125,52.1L125,52.1L125,52.1L125,52.1
      L125,52.1z M142,135.4H108l17-40.9L142,135.4z"/>
    </svg:g>
  </svg>
</div>

But I wish to keep templates clear and instert only few tags in it with url to separated svg file, somwehow like this:

<svg class="star">
        <use xlink:href="../../../assets/images/svg/star.svg"
               x="0"
               y="0" />
</svg>

Ho do I use separated svg files in components?

回答1:

Include your SVG files in src/assets folder and add the svg folder in your angular.json file.

"assets": [ "src/assets/svg/*" ]

This way you can include the file in your components as you wish.

回答2:

one way to do this is to set id property for your svg file and put your svg files in your asset folder. then use that id in mat-icon like this:

<mat-icon matSuffix svgIcon="your-id"></mat-icon>

this is a better way to do it; in this way you don't have to deal with svg tags in your UI html code. also this supports google icons.

though this works if you're using angular material.

If you have logo.svg:

1. Put it inside your src/assets folder
2. Include folder in the angular.json config: "assets": [ "src/assets" ]
3. Refer to it from template: <img src="assets/svg/logo.svg">
