Usage (client)
Available props
s3Url
and upload
are the only props that require configuration. All others have sensible defaults that may be overridden.
Prop | Type | Description
----------------- | ----------------- | -------------------------------------------
s3Url | string.isRequired | The url of your s3 bucket (https://my-bucket.s3.amazonaws.com
)
upload | object.isRequired | Upload options passed to react-s3-uploader. See react-s3-uploader for available options. Don't set onProgress
, onError
or onFinish
here - use the ones below
filename | string | Used as the default value if present. Filename of an image already hosted on s3 (i.e. one that was uploaded previously)
notDropzoneProps | array | A list of props to not pass to react-dropzone
isImage | func | A function that takes a filename and returns true if it's an image
imageComponent | func | Component used to render an uploaded image
fileComponent | func | Component used to render an uploaded file
progressComponent | func | Component used to render upload progress
errorComponent | func | Component used to render an error
children | node || func | If present the above components will be ignored in favour of the children
passChildrenProps | bool | If true we pass the current state to children of this component. Default is true. Set to false to avoid React warnings about unused props.
onDrop | func | Called when a file is dropped onto the uploader
onError | func | Called when an upload error occurs
onProgress | func | Called when a chunk has been uploaded
onFinish | func | Called when a file has completed uploading. Called once per file if multi=true
...rest | | All other props are passed on to the react-dropzone
component
Example
import DropzoneS3Uploader from 'react-dropzone-s3-uploader'
export default class S3Uploader extends React.Component {
handleFinishedUpload = info => {
console.log('File uploaded with filename', info.filename)
console.log('Access it on s3 at', info.fileUrl)
}
render() {
const uploadOptions = {
server: 'http://localhost:4000',
signingUrlQueryParams: {uploadType: 'avatar'},
}
const s3Url = 'https://my-bucket.s3.amazonaws.com'
return (
<DropzoneS3Uploader
onFinish={this.handleFinishedUpload}
s3Url={s3Url}
maxSize={1024 * 1024 * 5}
upload={uploadOptions}
/>
)
}
}
Custom display component
Specify your own component to display uploaded files. Passed a list of uploadedFile
objects.
// elsewhere
class UploadDisplay extends React.Component {
renderFileUpload = (uploadedFile, i) => {
const {
filename, // s3 filename
fileUrl, // full s3 url of the file
file, // file descriptor from the upload
} = uploadedFile
return (
<div key={i}>
<img src={fileUrl} />
<p>{file.name}</p>
</div>
)
}
render() {
const {uploadedFiles, s3Url} = this.props
return (
<div>
{uploadedFiles.map(this.renderFileUpload)}
</div>
)
}
}
// back in your uploader...
class S3Uploader extends React.Component {
//...
render() {
return (
<DropzoneS3Uploader
onFinish={this.handleFinishedUpload}
upload={uploadOptions}
>
<UploadDisplay />
</DropzoneS3Uploader>
)
}
}
Usage (server)
- Use s3Router from react-s3-uploader to get signed urls for uploads.
react-dropzone-s3-uploader/s3router
can be used as an alias forreact-s3-uploader/s3router
.- See react-s3-uploader for more details.
app.use('/s3', require('react-dropzone-s3-uploader/s3router')({
bucket: 'MyS3Bucket', // required
region: 'us-east-1', // optional
headers: {'Access-Control-Allow-Origin': '*'}, // optional
ACL: 'private', // this is the default - set to `public-read` to let anyone view uploads
}));
