Use this file to discover all available pages before exploring further.

This page walks you through cloning the Stranger Things Intro Creator repository, installing its dependencies, and running the development server so you can explore the code, test changes, or build a customized version on your own machine.

​
Prerequisites

Before you begin, make sure you have the following installed:
  • Node.js v14 or higher — nodejs.org. The project’s dev tooling requires Node.js; the final static output does not.
  • npm or yarn — npm ships with Node.js; install yarn with npm install -g yarn if you prefer it.
  • Git — git-scm.com for cloning the repository.
  • A modern browser — Chrome, Firefox, Edge, or Safari with ES6+ support for previewing the animations.

​
Setup

1

Clone the repository

Clone the project from GitHub and navigate into the project directory:
git clone https://github.com/modernharp/StrangerThingsIntroMaker.git
cd StrangerThingsIntroMaker
2

Install dependencies

Install the project’s development dependencies using your preferred package manager:
npm install
3

Start the development server

Launch the local dev server with live reload:
npm run dev
4

Open the app in your browser

Once the dev server starts, check your terminal output for the local URL it printed and open that address in your browser. The exact port depends on the project’s configuration and whether any other process is already using that port on your machine.

​
Project Structure

The Stranger Things Intro Creator is a static frontend project. Because the exact directory layout may vary depending on which version or fork you have checked out, refer to the files present after cloning rather than assuming a fixed structure. In general, a project of this type contains:
  • An HTML entry point that the browser loads directly
  • One or more CSS files containing the keyframe animations, glow effects, and layout rules
  • JavaScript modules that handle user input, animation sequencing, and shareable link generation
  • A package file listing development dependencies and available scripts
The only file confirmed in the upstream repository is README.md. If your clone looks different from what you expect, check the README for the most up-to-date project overview.

​
Making Changes

​
CSS Customization

The cinematic glow effect is driven by text-shadow declarations and CSS keyframe animations. Locate the CSS file responsible for the animation styles and look for the keyframe blocks or the class that applies the red glow. You can change the color, intensity, or timing without touching any JavaScript. Below is an example snippet showing how to adjust the glow color from the classic Stranger Things red to a cool cyan: 
/* Original red glow */
.intro-text {
  color: #ff0000;
  text-shadow:
    0 0 10px #ff0000,
    0 0 30px #ff0000,
    0 0 60px #cc0000;
}

/* Custom cyan glow */
.intro-text {
  color: #00e5ff;
  text-shadow:
    0 0 10px #00e5ff,
    0 0 30px #00b8d4,
    0 0 60px #0097a7;
}
Adjust the 0 0 60px spread radius to increase or decrease how far the light bleeds outward.

​
JavaScript

The animation logic — reading the user’s input, building the title sequence, and triggering each transition — lives in the project’s main script file. The code is written in ES6+ and is structured around the animation lifecycle (setup → play → loop/end). Look for clearly named functions corresponding to each phase when exploring or extending the behavior.
If you just want to create a Stranger Things-style intro without any local setup, the live site at strangerthingsintrocreator.com is always available and requires no installation whatsoever.

​
Next Steps

Once you’re happy with your changes locally, follow the Deployment guide to publish your customized instance to Vercel, Netlify, GitHub Pages, or your own server.
