Develop Insomnia

Development on Insomnia can be done on Mac, Windows, or Linux as long as you have Node.js and Git. See the .nvmrc file located in the project for the correct Node version.

Initial Dev Setup

This repository is structured as a monorepo and contains many Node.JS packages. Each package has its own set of commands, but the most common commands are available from the root package.json and can be accessed using the npm run … command. Here are the only three commands you should need to start developing on the app.

# Install and Link Dependencies
npm run bootstrap

# Run Tests
npm test

# Start App with Live Reload
npm run app-start


If you are on Linux, you may need to install the following supporting packages:

# Update library
sudo apt-get update

# Install font configuration library & support
sudo apt-get install libfontconfig-dev
# Install libcurl for node-libcurl
sudo dnf install libcurl-devel

Also on Linux, if Electron is failing during the bootstrap process, run the following

# Clear Electron install conflicts
rm -rf ~/.cache/electron


If you are on Windows and have problems, you may need to install Windows Build Tools

Editor Requirements

You can use any editor you'd like, but make sure to have support/plugins for the following tools:

  • ESLint - For catching syntax problems and common errors
  • JSX Syntax - For React components

Develop Inso CLI

  • Bootstrap: npm run bootstrap
  • Start the compiler in watch mode: npm run inso-start
  • Run: ./packages/insomnia-inso/bin/inso -v


Search for, discover, and install plugins from the Insomnia Plugin Hub!
