API

useTus hooks

const { upload, setUpload, isSuccess, isAborted, isUploading, error, remove } = useTus({ autoAbort, autoStart, uploadOptions, Upload });

useTus is a hooks that creates an object to perform Resumable file upload.

Arguments

• autoAbort (type: boolean | undefined) (default: true)

  • Whether or not to automatically abort uploads when useTus hooks is unmounted.

• autoStart (type: boolean | undefined) (default: false)

  • Whether or not to start upload the file after setUpload function.

• uploadOptions (type: TusHooksUploadFnOptions | undefined) (default: undefined)

  • Option to used by upload object that generated by that hooks.

• Upload (type: Upload | undefined) (default: undefined)

  • Option to specify customized own Upload class with this hooks.

About uploadOptions

This option extends the UploadOptions provided by tus-js-client, but it has been extended so that every callback can receive the upload instance as the final argument.

For detail type information of UploadOptions, please see here.

e.g.

setUplaod(file, {
  onSuccess: (upload) => {
    console.log(upload.url)
  },
  onError: (error, upload) => {
    console.log(error)

    setTimeout(() => {
      upload.start()
    }, 1000)
  }
})

• upload (type: tus.Upload | undefined)

  • Object to be used when performing Resumable file upload.
  • This value is undefined unless the setUpload function called.
  • For detail usage, please see here

Examples

The following are some example of how to use @hishprorg/sint-sit.

Uploading a file

The setUpload and upload.start functions can be used to perform resumable file uploads.

import { useTus } from '@hishprorg/sint-sit'

const Uploader = () => {
  const { upload, setUpload } = useTus();

  const handleSetUpload = useCallback((event: ChangeEvent<HTMLInputElement>) => {
      const file = event.target.files.item(0);

      if (!file) {
        return;
      }

      setUpload(file, {
        endpoint: 'https://tusd.tusdemo.net/files/',
        metadata: {
          filename: file.name,
          filetype: file.type,
        },
      });
    },
    [setUpload]
  );

  const handleStart = useCallback(() => {
    if (!upload) {
      return;
    }

    // Start upload the file.
    upload.start();
  }, [upload]);

  return (
    <div>
      <input type="file" onChange={handleSetUpload} />
      <button type="button" onClick={handleStart}>
        Upload
      </button>
    </div>
  );
};

It is also possible to automatically upload files after setUpload by specifying the autoStart option.

import { useTus } from '@hishprorg/sint-sit'

const Uploader = () => {
  const { upload, setUpload } = useTus({ autoStart: true });

  const handleSetUpload = useCallback((event: ChangeEvent<HTMLInputElement>) => {
      const file = event.target.files.item(0);

      if (!file) {
        return;
      }

      setUpload(file, {
        endpoint: 'https://tusd.tusdemo.net/files/',
        metadata: {
          filename: file.name,
          filetype: file.type,
        },
      });
    },
    [setUpload]
  );
  return (
    <input type="file" onChange={handleSetUpload} />
  );
};

Aborting a file upload

You can abort the upload by using the upload.abort function.

import { useTus } from '@hishprorg/sint-sit'

const Aborter = () => {
  const { upload } = useTus();

  const handleAbort = useCallback(() => {
    if (!upload) {
      return;
    }

    upload.abort();
  }, [upload]);

  return (
    <div>
      <button type="button" onClick={handleAbort}>
        Abort
      </button>
    </div>
  );
};

You can also specify the autoAbort option to automatically stop uploads when unmounting hooks.

import { useTus } from '@hishprorg/sint-sit'

const Uploader = () => {
  const { upload, setUpload } = useTus({ autoAbort: true });

  // omitted...
};

Default options of upload

You can specify default options in the defaultOptions props of the TusClientProvider.

import { useTusStore, DefaultOptions, TusClientProvider } from '@hishprorg/sint-sit'

const defaultOptions: DefaultOptions = (contents) => {
  const file = contents instanceof File ? contents : undefined;

  return {
    endpoint: 'https://tusd.tusdemo.net/files/',
    metadata: file
      ? {
          filename: file.name,
          filetype: file.type,
        }
      : undefined,
  };
};

const App = () => (
  <TusClientProvider defaultOptions={defaultOptions}>
    <Uploader />
  </TusClientProvider>
);

const Uploader = () => {
  const { setUpload } = useTusStore('cacheKey', { autoStart: true });

  const handleSetUpload = useCallback((event: ChangeEvent<HTMLInputElement>) => {
      const file = event.target.files.item(0);

      if (!file) {
        return;
      }

      // You no longer need to specify the options associated with upload.
      // If specified, it will override defaultOptions.
      setUpload(file);
    },
    [setUpload]
  );

  return (
    <div>
      <input type="file" onChange={handleSetUpload} />
    </div>
  );
};

Specify upload key

If you specify cacheKey as an argument to useTusStore, you can get the upload associated with it. This is useful for cross-page file uploads.

const SelectFileComponent = (file: File) => {
  // Create upload accosiated with 'upload-thumbnail' key
  const { setUpload } = useTusStore('upload-thumbnail')

  setUpload(file)
}

const UploadFileComponent = () => {
  const { upload } = useTusStore('upload-thumbnail')

  upload.start()
}
