Install Flmngr NPM package

Using the NPM package of Flmngr file manager is the easiest way to include it in your application and use it with any framework or without it.

Get the NPM package

The first step is to download the NPM package into your app. Go to your project directory and run the following command in the console:

Using NPM:

npm i --save flmngr

Using Yarn:

yarn add flmngr

Install the backend

You will also need to install the file manager backend somewhere on your server.

Call Flmngr from your code

Now you can import Flmngr namespace (the only namespace the package exports) and use it:

import Flmngr from "flmngr";

Flmngr.open({
    apiKey: "FLMNFLMN",                                  // default free key
    urlFileManager: 'https://fm.flmngr.com/fileManager', // demo server
    urlFiles: 'https://fm.flmngr.com/files',             // demo file storage

    isMultiple: false,                                   // let selecting a single file
    onFinish: (files) => {
        console.log("User picked:");
        console.log(files);
    }
});

This is an example of one case where you would need to open the file manager and wait until the user picks some files and receive these files in a callback after the dialog is closed. Flmngr.open({params}) is used for this.

There are many other available methods described in the API reference section. Live code samples are provided.

Sample

The full sample of using the NPM package is hosted on GitHub:

Open the file sample/index.html with your browser to run the app.

Optimization

The Flmngr NPM package loads a minimal part of Flmngr. Most of its components (file manager and image editor) will be automatically loaded from the official CDN on the first call of some method.

To ensure there is no delay on the first call, please consider preloading Flmngr using Flmngr.load({params}).

This call will not only preload the file manager and image editor from the CDN, but also preconfigure them. After passing some parameters into this function you should not include these parameters in any other calls unless you wish to override them.

We strongly recommend using this preload call and including these parameters:

• apiKey - your API key (or FLMNFLMN if you have not registered your own API key). It is the only parameter that is truly required and cannot be overridden.
• urlFileManager - URL of your PHP backend for the file manager. It is recommended but can be overridden in future calls.
• urlFiles - URL of where your files are located. It is also recommended and can be overridden in future calls.

So the optimized code will be:

import Flmngr from "flmngr";

// Starts async loading Flmngr code from CDN (this is non-blocking action)
Flmngr.load({
    apiKey: "FLMNFLMN",                                  // default free key
    urlFileManager: 'https://fm.flmngr.com/fileManager', // demo server
    urlFiles: 'https://fm.flmngr.com/files',             // demo file storage
});

// Somewhere when you need to open Flmngr
Flmngr.open({
    // Do not specify parameters already passed into Flmngr.load(...) before.
    // The same for other methods like Flmngr.upload(...), Flmngr.edit(...), etc.
    isMultiple: false, // let selecting a single file
    onFinish: (files) => {
        console.log("User picked:");
        console.log(files);
    }
});
