A helper library for creating templates based on react-docgen objects.

Install

npm install --save-dev react-docgen-renderer-template

Usage

Template Creators

const { template, type } = require('react-docgen-renderer-template');
 
// The template function gets an object of key/value pairs that represent type mappings for the template.
// The key is the type name and the value is a string to be displayed for that type.
// The string can also be a template string with functions inside that get the context (current prop definition) and a getType function that returns the type of a specific prop.  
const templateCreator = template({
  unknown: 'Unknown',
  func: 'Function',
  array: 'Array',
  object: 'Object',
  string: 'String',
  number: 'Number',
  bool: 'Boolean',
  node: 'ReactNode',
  element: 'ReactElement',
  symbol: 'Symbol',
  any: '*',
  custom: '(custom validator)',
  shape: 'Shape',
  arrayOf: type`Array[]<${({ context, getType }) => getType(context.type.value) }>`,
  objectOf: type`Object[#]<${({ context, getType }) => getType(context.type.value) }>`,
  instanceOf: type`${({ context }) => context.type.value}`,
  enum: type`Enum(${({ context, getType }) => context.type.value.map(value => getType(value)).join(', ')})`,
  union: type`Union<${({ context, getType }) => context.type.value.map(value => getType(value)).join('|')}>`
});
 
const template = templateCreator`This is my custom template to render a component docs.
I can use custom functions that will interpolate according to the metadata about the component, like so:
${({ context, getType}) => {
  //context contains all the metadata about the component docs.
  // context.componentName - the name of the component
  // context.srcLinkUrl - the URL to link the source of the of the file to
  // context.srcLink - the name to show for the link of the source of the file
  // context.description - the description of the component
  // context.props - the props the component has
  // context.composes - an array of component objects that this component composes in its prop types (each object in the array is of the same type as this context object)
  // context.isMissingComposes - whether or not there are some compositions that couldn't be resolved
  // 
  // getType - a function that takes a type of a prop and returns its value according to the type mappings
}}`

The result of the template should be passed as-is to a renderer instance, for example react-docgen-markdown-renderer.

Renderer Creators The TemplateObject contains two methods.

template.setPlugins This function gets an array of plugins to apply on the template. A plugin is an object with a function getTypeMapping that gets an options object with an extension - the extension of the template. That function returns an object with a key/value pairs, where each key is a type returned by react-docgen and the value is either a string to display for that type or a template string with functions as the templates (these will be called to populate the actual type) and should return a string.

template.instantiate This function instatiates the template.
It gets the context to apply on the template, and the extension this template will be saved as (typically the format).
This function returns the full blown template as a sring to be saved to the disk.
