How to transform SVGs into a collection of reusable React components.
SVGs (Scalable Vector Graphics) are an XML-based vector images used to define 2D graphics. An SVG file has the .svg
file extension.
SVGs are used in websites/webpages to seamlessly integrate 2D graphics into HTML. Recently, with the rise of Web Frameworks (Svelte, React, Angular, React, etc) SVGs have been a major occurrence and now largely used to embed images in components as icons.
In this post, we‘ll convert SVGs to React components using SVGR .
We will then publish them, as independent components, to Bit.dev , a cloud component hub, and make them available for all our projects.
SVGR
Transforms SVG into React Components.

Why convert SVGs into React components?
- Size reduction: SVG-to-React component conversion shaves off some excess SVG styling.
- No extra requests are made by the browser to fetch SVG images since they are now bundled with the JS.
- It allows for easier control and maintenance of SVGs since they are now React components.
- Verbose and obscure SVGs can be converted to customizable React components that expose a simple declarative API.
SVG and React
A common example of an SVG being used in React is non-other than the famous logo.svg
generated by create-react-app
when scaffolding a new React project.
- react-prj/ -src/ - logo.svg ... ... - package.json
The logo.svg
is the React logo:
Converting an SVG to a React component simply means creating a React component that renders an SVG. This does away with having extra .svg files lying around.
For example, we can create a React component that returns the React logo.svg
XML:
Then, we can use it anywhere:
There is no <img src={logo} className="App-logo" alt="logo" />
. It's been replaced with <ReactLogo />
. And there will be no need of logo.svg
because everything is in the ReactLogo component.
Here we manually converted the React icon SVG into a React component, but we can save ourselves some time by using SVGR to automate this process.
Using SVGR in the Command-Line
To use SVGR from command-line, install the CLI tool:
npm install @svgr/cli
Then, we call SVGR in the command-line, passing in the .svg file and other flags to replace different attributes with our own values.
svgr --icon --replace-attr-values "#063855=currentColor" logo.svg
The above command will take our logo.svg
file and convert it to a React component.
We can then copy the output shown in our terminal and create a new Logo.jsx
component.
Publish Converted Components to Bit.dev
Now that we have our logo.svg
file as a React component Logo.jsx
we can publish it to our collection on Bit. This way, we’ll make it available for our team to use in other projects.
Let’s install Bit globally on our machine:
$ npm install bit-bin --global
We’ll now initialize a Bit workspace in our project’s root directory:
$ cd svg-icons-project $ bit init
We can add multiple components at once but for this small demo we’ll specifically pick our Logo component:
$ bit add src/Logo.jsx
Now, since it is a React component we’ll need to configure a compiler for it (otherwise it would be coupled to our projects build setup — we don’t want that. We want our published components to move freely from one project to another).
The compiler is another component published on Bit. The --compiler
flag is our way to mention it should be used as a compiler.
$ bit import bit.envs/compilers/react --compiler
We’ll now tag our component with a version number
$ bit add --all 1.0.0
Login to our account (via our terminal)
$ bit login
And, finally, publish (‘export’) our component to the collection we’ve created on Bit.dev .
$ bit export chidume.svg-components
I’ve published another two converted components. Feel free to visit my component collection .
