Locating your components and organizing your style guide

Finding components

By default Styleguidist will search components using this glob pattern: src/components/**/*.{js,jsx,ts,tsx}.

It will pick up files like:

  • src/components/Button.js,
  • src/components/Button/Button.js,
  • src/components/Button/index.js.

But will ignore tests:

  • __tests__ folder,
  • files containing .test.js or .spec.js (or same for .jsx, .ts and .tsx).

If it doesn’t work for you, create a styleguide.config.js file in your project’s root folder and configure the patterns to fit your project structure.

For example, if your component files look like components/Button/Button.js, but you reexport them in components/Button/index.js (like export { default } from './Button') to simplify imports (components/Button instead of components/Button/Button), you need to skip index.js:

module.exports = {
components: 'src/components/**/[A-Z]*.js'
}
info

All paths are relative to the config folder.

tip

Use ignore option to exclude some files from the style guide.

tip

Use getComponentPathLine option to change the path you see below a component name.

Loading and exposing components

Styleguidist loads your components and exposes them globally for your examples to consume.

Identifier

It will try to use the displayName of your component as the identifier. If it cannot understand a displayName (for example if it is dynamically generated), it will fall back to something it can understand.

In each of the following cases, the global identifier will be Component.

PathCodeStyleguidist understands
/whatever.jsexport default function Component() { ... }displayName
/whatever.jsexport default function SomeName() { ... }
SomeName.displayName = 'Component';
displayName
/whatever.jsexport default function Component() { ... }
Component.displayName = dynamicNamer();
displayName at declaration
/component.jsconst name = 'SomeName';
const componentMap = {
[name]: function() { ... }
};
export default componentMap[name];
Filename
/component/index.jsconst name = 'SomeName';
const componentMap = {
[name]: function() { ... }
};
export default componentMap[name];
Folder name

Default vs named exports

Stylegudist will use an ECMAScript module’s default export or CommonJS module.exports if they are defined.

// /component.js
export default function Component() { ... }
// will be exposed globally as Component
// /component.js
function Component() { ... }
module.exports = Component;
// will be exposed globally as Component

If you use only named exports, Styleguidist will expose named exports from modules as follows...

If there is only one named export, it will expose that.

// /component.js
export function Component() { ... }
// will be exposed globally as Component

If there are several named exports, it will expose the named export which has the same name as the understood identifier.

// /component.js
export function someUtil() { ... }
// will not be exposed
export function Component() { ... }
// will be exposed globally as Component
caution

If you export several React components as named exports from a single module, Styleguidist is likely to behave unreliably. If it cannot understand which named export to expose, you may not be able to access that export.

Sections

Group components into sections or add extra Markdown documents to your style guide.

Each section consists of (all fields are optional):

  • name — section title.
  • content — location of a Markdown file containing the overview content.
  • components — a glob pattern string, an array of component paths or glob pattern strings, or a function returning a list of components or glob pattern strings. The same rules apply as for the root components option.
  • sections — array of subsections (can be nested).
  • description — A small description of this section.
  • sectionDepth — Number of subsections with single pages, only available with pagePerSection is enabled.
  • exampleMode — Initial state of the code example tab, uses exampleMode.
  • usageMode — Initial state of the props and methods tab, uses usageMode.
  • ignore — string/array of globs that should not be included in the section.
  • href - an URL to navigate to instead of navigating to the section content
  • external - if set, the link will open in a new window
  • expand - Determines if the section should be expanded by default even when tocMode is set to collapse in general settings

Configuring a style guide with textual documentation section and a list of components would look like:

// styleguide.config.js
module.exports = {
sections: [
{
name: 'Introduction',
content: 'docs/introduction.md'
},
{
name: 'Documentation',
sections: [
{
name: 'Installation',
content: 'docs/installation.md',
description: 'The description for the installation section'
},
{
name: 'Configuration',
content: 'docs/configuration.md'
},
{
name: 'Live Demo',
external: true,
href: 'http://example.com'
}
]
},
{
name: 'UI Components',
content: 'docs/ui.md',
components: 'lib/components/ui/*.js',
exampleMode: 'expand', // 'hide' | 'collapse' | 'expand'
usageMode: 'expand' // 'hide' | 'collapse' | 'expand'
}
]
}
