react18-file-viewer v0.0.10
react18-file-viewer
Extendable file viewer for web
Supported file formats:
- Images: png, jpeg, gif, bmp, including 360-degree images
- csv
- xslx
- docx
- Video: mp4, webm
- Audio: mp3
Usage
Note this module works best with react 18+
There is one main React component, FileViewer
, that takes the following props:
fileType
string: type of resource to be shown (one of the supported file
formats, eg 'png'
). Passing in an unsupported file type will result in displaying
an unsupported file type
message (or a custom component).
filePath
string: the url of the resource to be shown by the FileViewer.
onError
function optional: function that will be called when there is an error in the file
viewer fetching or rendering the requested resource. This is a place where you can
pass a callback for a logging utility.
errorComponent
react element optional: A component to render in case of error
instead of the default error component that comes packaged with react-file-viewer.
unsupportedComponent
react element optional: A component to render in case
the file format is not supported.
To use a custom error component, you might do the following:
// MyApp.js
import React, { Component } from 'react';
import logger from 'logging-library';
import {FileViewer} from 'react18-file-viewer';
import { CustomErrorComponent } from 'custom-error';
const file = 'http://example.com/image.png'
const type = 'png'
class MyComponent extends Component {
render() {
return (
<FileViewer
fileType={type}
filePath={file}
errorComponent={CustomErrorComponent}
onError={this.onError}/>
);
}
onError(e) {
logger.logError(e, 'error in file-viewer');
}
}
Development
There is a demo app built into this library that can be used for development purposes.
To start demo app
npm run dev
will start the demo app
To run the linter
npm run lint
Extending the file viewer
Adding supported file types is easy (and pull requests are welcome!). Say, for
example, you want to add support for .rtf
files. First, you need to create a
"driver" for that file type. A driver is just a component that is capable of
rendering that file type. (See what exists now in src/components/drivers
.) After
you've created the driver component and added it to src/components/drivers
, you
simply need to import the component into file-vewer.jsx
and add a switch clause
for rtf
to the getDriver
method. Ie:
case 'rtf':
return RtfViewer;
Roadmap
- Remove ignored linting rules and fix them
React + TypeScript + Vite
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
Currently, two official plugins are available:
- @vitejs/plugin-react uses Babel for Fast Refresh
- @vitejs/plugin-react-swc uses SWC for Fast Refresh
Expanding the ESLint configuration
If you are developing a production application, we recommend updating the configuration to enable type aware lint rules:
- Configure the top-level
parserOptions
property like this:
export default {
// other rules...
parserOptions: {
ecmaVersion: "latest",
sourceType: "module",
project: ["./tsconfig.json", "./tsconfig.node.json"],
tsconfigRootDir: __dirname,
},
};
- Replace
plugin:@typescript-eslint/recommended
toplugin:@typescript-eslint/recommended-type-checked
orplugin:@typescript-eslint/strict-type-checked
- Optionally add
plugin:@typescript-eslint/stylistic-type-checked
- Install eslint-plugin-react and add
plugin:react/recommended
&plugin:react/jsx-runtime
to theextends
list
