create-octane

Create an Octane app in a new directory.

npm create octane my-app
cd my-app
npm run dev

pnpm create octane my-app, yarn create octane my-app, and npx create-octane my-app all reach the same place.

Templates

You are asked which one you want, along with a project name, or you can say it up front:

npm create octane my-app -- --template spa
npm create octane my-app -- --template fullstack

npm needs that -- to forward the flag; pnpm and yarn forward it already, so drop it there.

spa is a client-only app: the compiler plugin, an index.html, and an entry that mounts one component.

index.html
vite.config.ts
tsconfig.json
package.json
.prettierrc
src/
  main.ts        mounts App into #root
  App.tsrx       the landing page
  styles.css     the reset and the theme tokens

fullstack adds octane.config.ts with routing, streaming SSR, hydration, and a production build, and it uses that surface rather than describing it: a second page, and an endpoint that returns a Response instead of a component.

index.html            carries the <!--ssr-head--> / <!--ssr-body--> markers
octane.config.ts      2 render routes + 1 server route
vite.config.ts
tsconfig.json
package.json
.prettierrc
src/
  App.tsrx            /
  Counter.tsrx        /counter — server-rendered, then hydrated
  Layout.tsrx         the frame both pages share
  styles.css          the reset and the theme tokens
  server/health.ts    GET /api/health

Both open on a page that links back into the documentation, and both are a working starting point rather than a directory of things to delete. The palette, typography and card styling are octanejs.dev's own, so a new app and the documentation look like one thing; src/styles.css holds the tokens and both colour schemes, and each component carries its own scoped <style>. There is no CSS framework to uninstall.

What it does

It runs octane create, which makes the directory and its package.json and then writes the TypeScript settings .tsrx needs, the bundler config, the scripts, and the entry files. That last part is the same code octane init runs against a project you already have, so the two cannot scaffold different projects.

This package is only the entry point. Everything above lives in @octanejs/cli, so npm create octane my-app and octane create my-app are the same command reached two ways.

Dependencies are installed through your package manager, which is also what records them in package.json. Pass --no-install to skip that, and the list to install by hand is printed instead.

Editor support

An Octane project builds, typechecks, and runs from the scaffold alone. Install TSRX Syntax for VS Code for syntax highlighting, diagnostics, navigation, completions, and TypeScript-aware editor support in .tsrx files. Pair it with the official Prettier extension for format on save. The scaffold's tsrx-tsc typecheck remains the command-line and CI check.
