$ npm install hapi-footprints --save
// ES6 Syntax
import Footprints from 'hapi-footprints';


const footprints = new Footprints(options, overrideRoutes)

Creates a new instance of footprint.

  • options (Object) Optional
    • prefix (string)
      • Defaults to: /api
      • Prefix for the routes created by footprints
    • excludeModels (Array)
      • Defaults to: []
      • Example: ['user', 'post']
      • An array of model names to exclude from creating the routes.
    • excludeActions (Object)
      • Defaults to: {}
      • Example: {modelName: ['find', 'remove']}
      • An object for excluding a particular action or actions.
    • routeDefaults (Object)
      • Defaults to: {}
      • Example: {config: {tags: ['api']}}
      • An object which will be merged to every routes generated. Useful adding configurations for hapi.
    • cache (Object or false)
      • Defaults to:
          cache: 'redisCache',
          expiresIn: 1000 * 60 * 5,
          segment: '!footprints',
          generateTimeout: 300,
      • Disables cache when false, else configurations are passed down to hapi's server method's options. Caching is available for find, findCount, findOne actions. See here for more information about actions.
    • handler (Object)
      • See the comment-outs below for description of each keys available
      • Defaults to:
        // name of handler to register
        name: 'footprints',
        // override default options of the handler
        options: {
          // will be deleted
          model: null,
          // enable cache for this footprint
          // works only on 'GET' method actions
          cache: true,
          // function to inject before executing a query to the database
          // could be used for caching the response, custom errors, etc.
          // it is injected before caching, therefore caching will not work.
          // NOTE: this option will not be executed in association routes
          // example: (query, options, callback) => { query.exec(callback) };
          injectBeforeQuery: false,
          // primaryKey of model, defaults to 'id' when set to false
          primaryKey: false,
          // paginations
          pagination: true,
          // default limits for 'find'
          limit: 30,
          // max limit for 'find'
          maxLimit: 30,
          // default offset
          offset: 0,
          // soft deletes
          softDelete: {
            // enable soft deletes
            enabled: true,
            // set attribute for soft deletes
            attr: 'deletedAt',
          // population
          populateByDefault: true,
          populateLimit: 30,
          // associations
          child: {
            // primaryKey for the child model
            primaryKey: false,
  • overrideRoutes (Object) Optional
    • Route configurations for specific route-actions.
    • Example:
        modelName: {
          find: {
            // any hapi route configurations here,
            // but NOT "path" or "method", footprints will throw an error.
          findCount: {},
          findOne: {},
          create: {},
          update: {},
          populate: {},
          populateWithId: {},
          populateCount: {},
          add: {},
          addWithId: {},
          destroy: {},
          remove: {},
        // and so on...

Exposed by plugin

  • a handler, with a name passed in with
    • this handler is used for the actual route.handler, and can be used inside the overrideRoutes
  • a server method called cacheQuery, when options.cache is not disabled.
    • this server method is used for caching wateline model's query, by the criteria used in the query
