> A lightweight library that makes it easier to use SVG icons in your Angular Application [![MIT](https://img.shields.io/packagist/l/doctrine/orm.svg?style=flat-square)]() [![commitizen](https://img.shields.io/badge/commitizen-friendly-brightgreen.svg?style=flat-square)]() [![PRs](https://img.shields.io/badge/PRs-welcome-brightgreen.svg?style=flat-square)]() [![styled with prettier](https://img.shields.io/badge/styled_with-prettier-ff69b4.svg?style=flat-square)](https://github.com/prettier/prettier) [![All Contributors](https://img.shields.io/badge/all_contributors-5-orange.svg?style=flat-square)](#contributors-) [![ngneat](https://img.shields.io/badge/@-ngneat-383636?style=flat-square&labelColor=8f68d4)](https://github.com/ngneat/) [![spectator](https://img.shields.io/badge/tested%20with-spectator-2196F3.svg?style=flat-square)]() The `svg-icon` library enables using the `` tag to directly display SVG icons in the DOM. This approach offers an advantage over using an `` tag or via the CSS `background-image` property, because it allows styling and animating the SVG with CSS. For example, if the `fill` or `stroke` properties of elements in the svg are set to `currentColor`, they will have the color defined for the containing DOM element. So the color can easily be changed by changing the color style on the `svg-icon` element. ## Installation ``` npm i @ngneat/svg-icon npm i @ngneat/svg-generator --save-dev ``` ## Icons Preparation - Add the icons to `src/assets/svg` - Add an alias to the `tsconfig` file (optional): ```json { "paths": { "@app/svg/*": ["src/app/svg/*"] } } ``` - Configure the `@ngneat/svg-generator` to clean and extract the icons content. Add the following to your `package.json` file: ```json { "scripts": { "prestart": "npm run svg", "prebuild": "npm run svg", "svg": "svg-generator" }, "svgGenerator": { "outputPath": "./src/app/svg", "srcPath": "./src/assets/svg", "svgoConfig": { "plugins": [ "removeDimensions", "cleanupAttrs", { "name": "convertColors", "params": { "currentColor": true } } ] } } } ``` It can be modified to meet your needs. - Add the `outputPath` to your `gitignore` file - Run `npm run svg` ## Icons Rendering Use the `provideSvgIcons` to register the icons: ```ts import { provideSvgIcons } from '@ngneat/svg-icon'; import { settingsIcon } from '@app/svg/settings'; bootstrapApplication(AppComponent, { providers: [provideSvgIcons([settingsIcon])], }); ``` Now we can import the **standalone** `SvgIconComponent` and use the `svg-icon` component: ```ts import { SvgIconComponent } from '@ngneat/svg-icon'; @Component({ imports: [SvgIconComponent], template: ` `, }) export class FooComponent {} ``` _Note_ that the `key` should be striclty typed based on your icons. You can also export the `SvgIcons` type from the library if you need it. ## Register icons locally In lazy load modules or lazy routes, we can use the `provideSvgIcons` method, for register icons accessible locally in these modules: ```ts import { dashboardIcon } from '@app/svg/dashboard'; import { userIcon } from '@app/svg/user'; import { provideSvgIcons } from '@ngneat/svg-icon'; @NgModule({ declarations: [DashboardComponent], providers: [provideSvgIcons([userIcon])], imports: [DashboardRoutingModule], }) export class DashboardModule {} // OR in a Route def { path: 'dashboard', providers: [provideSvgIcons([userIcon])], component: DashboardPageComponent } ``` Note that we're NOT using a barrel file (i.e `index.ts`). This will make sure we only **load** the SVG files we use in the current module. ## Group Icons There are cases where we want to group multiple SVG icons. For example, we might have a `notifications` feature, and we need to load SVG icons such as Slack, Email, etc. In such cases, create a unique directory, and put the related icons inside it. For example: ``` home.svg user.svg /notifications - slack.svg - email.svg ``` This will create a `notifications` folder with a `barrel` file that export the SVG icons inside the folder under a const named `${folderName}Icons`: ```ts import { notificationsIcons } from '@app/svg/notifications'; @NgModule({ providers: [provideSvgIcons(notificationsIcons)], }) export class NotificationsModule {} ``` ## Icon Sizing To control the SVG size, we use the `font-size` property as described in this [article](https://css-tricks.com/control-icons-with-font-size/). You also have the option to pass fixed sizes and use them across the application: ```ts import { provideSvgIconsConfig } from '@ngneat/svg-icon'; bootstrapApplication(AppComponent, { providers: [ provideSvgIconsConfig({ sizes: { xs: '10px', sm: '12px', md: '16px', lg: '20px', xl: '25px', xxl: '30px', }, defaultSize: 'md', icons, }), ], }); ``` They are used in the `size` input: ```html ``` ## Inputs ```ts @Input() key: string; @Input() size: string; @Input() fontSize: string; @Input() color: string; @Input() width: string | number; @Input() height: string | number; @Input() noShrink: boolean; ``` ## SvgIconRegistry You can inject the `SvgIconRegistry`, and get existing SVG icons or register new ones: ```ts import { SvgIconRegistry } from '@ngneat/svg-icon'; interface Icon { name: string; data: string; } @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.scss'], }) export class AppComponent { constructor(private registry: SvgIconRegistry) { registry.register([Icon, Icon, Icon]); registry.register(Icon); registry.get(name); registry.getAll(); } } ``` You can also use the `injectRegisterIcons` method to register icons using the new `inject` API: ```ts import { injectRegisterIcons } from '@ngneat/svg-icon'; interface Icon { name: string; data: string; } @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.scss'], }) export class AppComponent { constructor() { injectRegisterIcons([Icon, Icon, Icon]); } } ``` ## Missing Icon You can define **missingIconFallback** which will be used if icon is not found in registry: ```ts import { provideSvgIconsConfig } from '@ngneat/svg-icon'; import { unknownIcon } from '@app/svg/unknown'; bootstrapApplication(AppComponent, { providers: [ provideSvgIconsConfig({ missingIconFallback: unknownIcon, }), ], }); ``` ## Custom config file The `svgGenerator` config object is placed by default in your main `package.json`. It can also be placed in any location supported by the [Cosmiconfig library](https://github.com/davidtheclark/cosmiconfig) such as a custom `.svgGeneratorrc.json` file. The config object is looked for in the project root directory by default. If your config object is located in another directory, you can specify it through the `--config-dir` option of the `svg` CLI: `npm run svg --config-dir=/your/custom/dir/where/the/config/is/located`. The config object will then be looked for in all valid [Cosmiconfig library](https://github.com/davidtheclark/cosmiconfig) locations starting from that directory and going up the directory tree until a config is found.
