features

• provides development architecture which linearly scales complexity as your app evolves.
• provides prescriptive opinions to bootstap teams onto a consistent development platform across projects.
• everything is a depject module that can be overridden or combined.
• app file structure maps to app modules, making it easy to separate concerns and get things done.
• provides full stack app server for both development and production.
• consistent concepts across front and back end.

demos

• catstack.herokuapp.com: this repo's ./example deployed to heroku

concepts

• modules
• streams
• services
• state, actions, effects, html views
• data logs and views
• commands

bin

• generate
• dev
• server
• test
• lint

gen

test

runs pull-test tests

can optionally take a glob

npm run test -- './todos/**/*.test.js'

default glob is ./**/*.test.js ignoring node_modules

lint

checks for standard style

can optionally take a glob

npm run lint -- './todos/**/*.js'

default glob is ./**/*.js ignoring node_modules

directory structure

the catstack files are organized in the following hierarchy:

${topic} / ${type} / ${module}.js

• config/
  • config/index.js
  • config/${ NODE_ENV }.js
• ${ topic }/
• tests are any files that end in .test.js

topic overview

in contrast to frameworks like Rails which split our app into directories for each "type" of file (models, views, controllers), our app is split into directories for each conceptual topic, where each topic contains the various types of files within that topic.

each topic directory may contain any of:

• state.js: exports initial store state
• action/*.js: exports store actions
• effect/*.js: exports effects
• getter/*.js: exports reselect getters
• page/*.js: exports routed views
• element/*.js: exports presentation views
• helper/*.js: exports helper functions
• service.js: exports vas service

${ topic }/state.js

// cats/state.js`
module.exports = {
  create: () => ({
    init: () => ({
      model: {},
      effect: null
    })
  })
}

/${ topic }/action/*.js

// cats/action/create.js
module.exports = {
  create: () => ({
    update: (model, action) => {
      console.log('cat:create', model, action)
      return model
    }
  })
}

/${ topic }/effect/*.js

// cats/effect/fetch.js
module.exports = {
  create: () => ({
    run: (model, effect) => {
      console.log('cat:fetch', effect)
    }
  })
}

/${ topic }/get/*.js

// cats/get/cats.js
module.exports = {
  create: () => (state) => state.cats
}

/${ topic }/page/*.js

// cats/page/show.js
module.exports = {
  needs: {
    'app.layout.main': 'first',
    cats: {
      'element.profile': 'first',
      'get.show': 'first'
    }
  },
  create: (api) => ({
    route: '/cats/:catId',
    layout: api.layout.main,
    get: api.cats.get.show,
    view: api.cats.element.profile
  })
}

/${ topic }/element/*.js

// cats/element/profile.js
module.exports = {
  needs: {
    'inu.html': 'first'
  },
  create: (api) => ({
    view: (cat) => api.html`
      <div>${cat.name}</div>
    `
  })
}

/${ topic }/service.js

// cats/service.js
module.exports = {
  needs: {
    data: 'first'
  },
  manifest: {
    all: 'source',
    get: 'async'
  },
  create: function (api) {
    const cats = [{
      name: 'Fluffy'
    }, {
      name: 'Zoe'
    }]

    return {
      methods: { all, get }
    }

    function all () {
      return pull.values(cats)
    }

    function get (id, cb) {
      cb(null, data[id])
    }
  }
})

FAQ

how do i do relations between models?

implement them in your getters.js file as selectors.

in the future, we should extract common relations into helper creators.
