SyntaxError: 'import' and 'export' may only appear at the top level

[RobinJayaswal]

Just installed latest, and am seeing:

SyntaxError: 'import' and 'export' may only appear at the top level (8656:0) while parsing /node_modules/filestack-js/build/browser/index.esm.js

I am using gulp, with babel to transpile to es2015, and this configuration works with other modules. Anything special about this module?

Bump. I'm having the same issue.

I've run into this as well, but it comes from the filestack-js client. Once I had the package compiled with Meteor it started working just fine.

[StorytellerCZ]

The issue on the client: https://github.com/filestack/filestack-js/issues/142 Though I doubt that the workarounds there will be of any use here...

I'm getting the following error in my Meteor project

/node_modules/filestack-js/build/browser/index.esm.js:19042 
Uncaught (in promise) SyntaxError: Unexpected token export

Any suggestions from team Filestack?

Here's a really dirty workaround, for those experiencing the same issue with filestack-react and Meteor.

1 - Remove filestack-react from your project:

npm rm filestack-react

2 - Add filestack-js:

npm i --save filestack-js

3 - Create a new react component in your project, called ReactFilestack.jsx and paste in the code found here: https://github.com/filestack/filestack-react/blob/master/src/ReactFilestack.jsx

Then change the import statement for filestack to point directly to /node_modules/filestack-js/build/browser/filestack.min.js

You can then use this new component in place of the filestack-react package.

import React, { Component } from 'react';
import * as filestack from '/node_modules/filestack-js/build/browser/filestack.min.js';
import PropTypes from 'prop-types';

class ReactFilestack extends Component {
  static defaultProps = {
    file: null,
    link: false,
    buttonText: 'Pick file',
    buttonClass: '',
    onSuccess: result => console.log(result),
    onError: error => console.error(error),
    mode: 'pick',
    options: {},
    security: null,
    children: null,
    render: null,
    cname: null,
    sessionCache: false,
    preload: false,
  };

  static propTypes = {
    file: PropTypes.objectOf(PropTypes.any),
    apikey: PropTypes.string.isRequired,
    link: PropTypes.bool,
    mode: PropTypes.string,
    buttonText: PropTypes.string,
    buttonClass: PropTypes.string,
    onSuccess: PropTypes.func,
    onError: PropTypes.func,
    options: PropTypes.objectOf(PropTypes.any),
    security: PropTypes.objectOf(PropTypes.any),
    children: PropTypes.node,
    render: PropTypes.func,
    cname: PropTypes.string,
    sessionCache: PropTypes.bool,
    preload: PropTypes.bool,
  };

  constructor(props) {
    super(props);
    const { apikey, security, cname, sessionCache, preload, options } = this.props;
    const client = filestack.init(apikey, {
      security,
      cname,
      sessionCache,
    });
    this.state = {
      client,
      picker: preload ? client.picker({ ...options, onUploadDone: this.onFinished }) : null,
    };

    this.onFinished = this.onFinished.bind(this);
    this.onFail = this.onFail.bind(this);
  }

  onClickPick = event => {
    event.stopPropagation();
    event.preventDefault();

    const { client, picker } = this.state;

    const { options, mode, file, security, preload } = this.props;

    this.callPicker(mode, options, file, security, preload, client, picker)
      .then(this.onFinished)
      .catch(this.onFail);
  };

  onFinished = result => {
    const { onSuccess } = this.props;
    if (typeof onSuccess === 'function' && result) {
      onSuccess(result);
    }
  };

  onFail = error => {
    const { onError } = this.props;
    if (typeof onError === 'function') {
      onError(error);
    } else {
      console.error(error);
    }
  };

  callPicker = (mode, options, file, security, preload, client, picker) => {
    const { url, handle } = options;
    delete options.handle;
    delete options.url;

    if (mode === 'transform') {
      return new Promise((resolve, reject) => {
        try {
          resolve(client.transform(handle, options));
        } catch (err) {
          reject(err);
        }
      });
    } else if (mode === 'retrieve') {
      return client.retrieve(handle, options);
    } else if (mode === 'metadata') {
      return client.metadata(handle, options);
    } else if (mode === 'storeUrl') {
      return client.storeURL(url, options);
    } else if (mode === 'upload') {
      return client.upload(file, options);
    } else if (mode === 'remove') {
      return client.remove(handle, security);
    }

    return new Promise(resolve => {
      if (preload) {
        picker.open();
        resolve();
      } else {
        client.picker({ ...options, onUploadDone: resolve }).open();
      }
    });
  };

  render() {
    const { buttonClass, buttonText, link, children, render: CustomRender } = this.props;
    if (CustomRender) {
      return <CustomRender onPick={this.onClickPick} />;
    }
    const Tag = link ? 'a' : 'button';
    return (
      <Tag name="filestack" onClick={this.onClickPick} className={buttonClass}>
        {children || buttonText}
      </Tag>
    );
  }
}

export default ReactFilestack;

@ninjaPixel @StorytellerCZ @graphographer The newest version is using filestack-js 2.0.5 and it should fix this problem.

@AndrzejSala I've just tried filestack-react 3.1.0 and this error is still there
