README

Bare-bones file picker for react with no dependencies (other than react >= 16.8, bootstrap and react-bootstrap) or bells and whistles. What it does - it allows you to select multiple files and order and / or delete them. That's it. You can also set a limit on the number of files user can select and the file types. This package will not install react or bootstrap for you. It assumes you will add those dependencies (all such dependencies that this package relies on you to install are declared under peerDependencies in package.json) in your package.json along-side react-bootstrap-file-input. Example screenshot:

How to use it

Assuming you know how to write a React app:

import FileInput from "@siddjain/react-bootstrap-file-input";
import "bootstrap/dist/css/bootstrap.min.css";

export default function App() {
  return (
    <div className="App">
      <FileInput maxFileCount={3} accept=".png,.jpg,.jpeg" />
    </div>
  );
}

Demo

Note: please use following command to build your app (the app which will use this package as a dependency):

GENERATE_SOURCEMAP=false npm run build

You need to set GENERATE_SOURCEMAP=false or you will get a warning when you run the app. See this.

API

FileInput takes following optional inputs:

• onChange: an event handler that is called whenever the file list changes (addition, deletion or change in order of items in the list)
• maxFileSize: a number. units: bytes. If user selects a file whose size is greater than maxFileSize a warning symbol is displayed. The file is still selected and added to list of files.
• maxFileCount: a number. maximum number of files user should be able to select.
• accept: same as accept. a string that defines the file types the file input should accept.
• value: (for advanced users) this is useful if you will be using FileInput in a multi-step (multi-page) form where user can go back and forth. An array of File objects to initialize FileInput's list of files.

Known Issues

If you open a file, then remove it from selection, you cannot select (open) it again immediately (e.g., if you removed it from the selection by mistake). You have to open another file first. Then you can re-open or select the previous file.

Rest of this document is for me - the developer of this project.

Build Instructions

Install Dependencies

npm i

Build

npm run build

Test Instructions

Below are instructions on how to test the package locally before publishing to npm. To test the package, create a demo project that will import this package and use it. E.g., like this (full source code of demo project is not shown):

import FileInput from "@siddjain/react-bootstrap-file-input";
import "bootstrap/dist/css/bootstrap.min.css";

export default function App() {
  return (
    <div className="App">
      <h1>Hello CodeSandbox</h1>
      <FileInput></FileInput>
    </div>
  );
}

Below are instructions how to use this package from a demo project.

Step 1: Pack the code

npm pack 

This will pack all the files under files in package.json and create a tarball (.tgz file).

Step 2: Copy over tarball to demo folder

Below we copy over the tarball to the demo project:

$ mv siddjain-react-bootstrap-file-input-1.0.0.tgz ../react-bootstrap-file-input-demo

Step 3: Install tarball in demo project

$ npm i siddjain-react-bootstrap-file-input-1.0.0.tgz

Tip: Some docs suggest using npm link to test a package locally before publishing to npm. Do NOT use npm link otherwise you run into invalid hook call. see this.

Publishing the package

npm publish --access public
