Free Node.js Discord Bot Hosting Guide
Learn how to deploy Discord.js and other Node.js Discord bots on free hosting.
Node.js is one of the most common runtimes used for Discord bots. A reliable deployment depends on the correct Node.js version, package installation, environment variables and startup file.
Understanding package.json
package.json describes project metadata, dependencies and scripts. It is one of the first files you should inspect when deploying an unfamiliar Node.js bot.
{
"scripts": {
"start": "node index.js"
}
}Install dependencies
Run npm install from the project directory when package.json defines the dependencies required by the application.
npm installChoose the correct Node.js version
Using a runtime that is too old can produce syntax or package compatibility errors. Use the version required by the project and its dependencies instead of selecting a version randomly.
Configure the startup file
Common entry files include index.js, app.js and src/index.js. package.json can also define a start script so the application launches through npm start.
Handle environment variables
Store values such as DISCORD_TOKEN, database credentials and API keys outside public source code whenever possible.
