Wait, did we have utterance-react-component
already? Is another component needed?
My main motivation is to resolve the bug that I encountered when using utterance-react-component
.
utterance-react-component
loads the script https://utteranc.es/client.js
and passes the props to that script. The problem is the component will have the same bugs as client.js
and at the point I am writing this still exists.
Refer to utterances issue #624 and utterances-component issue #393.
So, I took client.js
, rewrote that using React API, and made it into a React component.
Installation
Install from npm
npm install react-utterances-client
yarn add react-utterances-client
Install from repository
Recommended to specify a version tag like this for installation from the repository like below for stability.
npm install github:mddanish00/react-utterances-client#vX.X.X
yarn add react-utterances-client@github:mddanish00/react-utterances-client#vX.X.X
Check out the repository tags list here.
Remove #vX.X.X
to fetch the latest changes from the main
branch. Beware of instability!
Usage
Basic Usage
import { Utterances } from 'react-utterances-client';
const Comments = () => {
return (
<Utterances
repo="people/example-project"
theme="github-dark"
issueTerm="title"
/>
);
};
You just need to specify the repository that you will be using its issues for comments.
The repository you want to use must:
- The repository is set to Public.
- The utterances app is installed on the repository.
- Make sure Issues is turned on if your repository is a fork.
After that, you can specify your theme or just omit theme
prop to use the default theme and decide on issue mapping with your current page.
For this, it is better to read Blog Post ↔️ Issue Mapping
on the official site for a more details explanation of the options.
You can only use one of the below props for this:
- For
pathname
,url
,title
,og:title
or specific terms, you need to useissueTerm
prop. - For
issueNumber
, you need to provide the issue number toissueNumber
prop.
Event Handler
import * as React from 'react';
import { Utterances } from 'react-utterances-client';
const Comments = () => {
const handleLoad = React.useCallback((e)=>{
console.log('Component is loaded!')
}, []);
return (
<Utterances
repo="people/example-project"
theme="github-dark"
issueTerm="title"
onLoad={handleLoad}
/>
);
};
Only two event handlers can be used right now:
- onLoad: When this component finishes loading.
- onError: When this component throws errors.
This will be attached to the iframe onLoad
and onError
.
The e
will be passed down to the event handler.
Token Storage
This feature is experimental. It need more feedback from the users. It may be removed in later versions.
import { Utterances } from 'react-utterances-client';
const Comments = () => {
return (
<Utterances
repo="people/example-project"
issueTerm="title"
tokenStorage="session"
/>
);
};
Every time the user logs in to their GitHub account on the Utterances site, this component will keep the token in the redirected URL into localStorage. The problem with this is the Utterances don't provide any way to log out of the account from the site.
Also, based on my reading on the Utterances project code, the token has a 1-year expiry date.
So, I added an option to keep the token in SessionStorage instead. LocalStorage will survive when the site or tab closes but SessionStorage will auto-delete them. This is a better approach in my opinion.
The component will still set the storage to LocalStorage by default.
Recommended to create a way for the user to clear Login data like a button. Like this.
import { Utterances } from 'react-utterances-client';
const Comments = () => {
return (
<>
<button onClick={()=>localStorage.removeItem('utterances-session')}>
Clear Login Data
</button>
<Utterances
repo="people/example-project"
issueTerm="title"
tokenStorage="session"
/>
</>
);
};
Placeholder
This feature is experimental. It need more feedback from the users. It may be removed in later versions.
import { Utterances } from 'react-utterances-client';
const Comments = () => {
return (
<Utterances
repo="people/example-project"
issueTerm="title"
placeholder={true}
/>
);
};
Placeholder is a component that will display when the Utterances component is loading. You need to enable this feature explicitly to use it. You can even provide your own Placeholder Component through placeholder
prop.
This prop will set
loading
prop toeager
regardless what you set.
Customization
import { Utterances } from 'react-utterances-client';
const Comments = () => {
return (
<Utterances
repo="people/example-project"
theme="gruvbox-dark"
issueTerm="title"
iframeClassName="text-light"
containerStyle={{ background: '#282828'}}
/>
);
};
Theme
List of themes that are available for use with Utterances:
- github-light
- github-dark
- preferred-color-scheme
- github-dark-orange
- icy-dark
- dark-blue
- photon-dark
- boxy-light
- gruvbox-dark
For preferred color scheme
, it will depend on your OS's dark mode settings. If disabled, github-light
. If enabled, github-dark
.
You can see the Theme preview on the official site. Also, available in Comments Demo.
ClassName and Style
This component exposes the className
prop and style
prop for both Container div (containerClassName
, containerStyle
) and iframe (iframeClassName
, iframeStyle
). This opens up the possibility when customizing the appearance of the component.
For example, you can use the containerStyle
prop to customize the container background.
Or, pass Bootstrap classes like text-light
or bg-primary
to containerClassName
prop.
Or, you Emotion css
function and pass the generated className to the containerClassName
prop.
Go wild!

Plan
We need to break down what client.js
does.
- Processing the provided props
- Collect attributes from the page that the script loaded from
- And, finally, construct the URL based on those information and load iframe with that URL.
As the name implies, the client.js
is just a client. And so is this component.
I will implement everything that client.js
can do and also any future updates for client.js
. I also will consider any suggestions that will improve the component itself.
I can fix it if something is wrong with the client functions above.
But if you want new features and have problems with Utterances itself, you have better luck in posting your issues in the Utterances repository instead.
