Getting started
with yFiles for HTML

First-time setup

The Getting Started section of the Developer's Guide explains the following steps in detail.
Of course, you need a yFiles package and a valid license to use yFiles. If you don't have one yet, you can download a free trial version from our customer center or via the yFiles Dev Suite.

Prerequisites

The demos need an installed Node.js to run properly.

Install Nodes.js 16 or newer
https://nodejs.org/
load from Vimeo

Running the demos locally

The best way to run the demos locally is with the included dev server.

Run the start_demos script in the yFiles-for-HTML-Complete-2.6.0.3 directory:
start_demos.cmd (Windows)
start_demos.sh (Linux)
start_demos.command (MacOS)
Open the demos
You can explore them at /demos-ts or /demos-js.

Working with yFiles

Install an IDE
We recommend WebStorm (30 days free). You can also use Visual Studio Code as a free alternative.
Open the project
Open the yFiles-for-HTML-Complete-2.6.0.3 directory as project in your IDE.
WebStorm will automatically start the dev server in the background. So you don't have to start the server manually each time.
Modify the demo code and observe changes
The dev server automatically reloads the demo's page after changes in the source code.

Intro to yFiles

There are three approaches to learning the yFiles basics. You can choose any of them, according to your personal preference.

Integrate yFiles into an existing project

yFiles is compatible with all modern web application frameworks, so it can be easily integrated into your existing application. After including the library, there are multiple demos show you how to add graphs to your application.

General integration

The easiest way to include the yFiles for HTML library into your project is to use it as a local npm module. Find lib-dev/es-modules/yfiles-26.0.3-dev.tgz in your yFiles package and add it as a dependency to your package.json.

>npm install --save <yFiles package path>/lib-dev/es-modules/yfiles-26.0.3-dev.tgz

The npm module comes with support of code completion for both JavaScript and TypeScript. If necessary, these typings can be generated and included in existing projects at any time.

For more information on how to set up this module, see the Working with the yFiles npm module chapter in the Developer's Guide.

Before you can start developing, register the yFiles for HTML license.
