Sceptre NPM | npm.io

Sceptre

Implement Next.js style page directories in your single page application by generating routing definitions from a page directory.

Installation

Install the CLI

npm install -g sceptre

Page folder structure

Pages are defined using a folder structure in your application. Subfolders denote path segments, while pages map to index.tsx or index.jsx files. When using sceptre, each page is given it's own directory in which assets and styles can be placed, allowing for a clean and structured page setup.

Exporting pages

Each page is expected to contain a default export of it's RouteObject. The path property will automatically be populated when parsing the tree, so it may be omitted.

const IndexPage = () => {
    return (
        <div>
            Page content
        </div>
    )
};

IndexPage.info = {
	title: 'Index Page'
}

export default IndexPage;

URL Parameters

Parameters can be defined by using [name] as folder name. This will automatically translate into :name when building routes.

We also support a other parameter type: ... which will match any path segment.

Index mapping

Folders named @ will map to the index page of the parent directory.

Parent pages

You can add a parent pages by making a folder named _ anywhere in your file tree. Parent pages are responsible for placing an <Outlet /> where child routes will be rendered. Routes can be parented any number of times, each rendering in its closest parent outlet.

Visual example:

/example/_				- Responsible for rendering outlet 1
/example/@				- Rendered inside outlet 1
/example/page/_			- Rendered inside outlet 1 and responsible for rendering outlet 2
/example/page/@			- Rendered inside outlet 2
/example/page/child 	- Rendered inside outlet 2

Example folder structure

pages/
    @/
        index.tsx
        styles.tsx
    help/
        index.tsx
        style.scss
    settings/
        _/
            index.tsx
        overview/
            index.tsx
        [param]/
            index.tsx
    folder/
        _/
            index.tsx
        [...]/
            index.tsx
            style.scss

The above example translates to the given routes

/
/help
/settings/overview
/settings/:param
/folder/*

Usage

sceptre ./src/pages/**/index.tsx ./src/generated/routes.ts --base ./src/pages

This command will compile all index components placed recursively within the pages directory and generates a routes.ts.

Base directory

The --base flag should point to the directory containing all pages. By default it is set to the current execution directory.

Identing

You can optionally pass --indent none | tab | <number> to control the indentation of the generated routing configuration. By default indentation is disabled.

Forced js extensions

Certain environments may require all script file imports to end with .js regardless of their actual extension. In this case you can pass the --force-js flag.
