What is PERMA-DATA ?

PERMA-DATA is being developped to agregate [plant data] from various but consistent sources.

Its main concern is to make this data available for everybody, while ensuring its quality and maintainability.

The principles stated below define some key objectives.

Principles

  1. Gather and abstract plant data Extract [plant data] from various supports and store it as atomic and interoperable value.

  2. Shapes plant data for user From this raw and numerous atomic [plant data] (principle 1), build a user-friendly interface to display consistent data views.

  3. Continuous improvement The application will never stop improving in term of reliability and features.

  4. Maintainable infrastructure Development and hosting aims for the lowest energetic and financial costs.

  5. Minimalist features and workflows To enforces its low consumption orientation (principle 3) and save user time and attention, application remains as simple as possible.

  6. Playing is learning As part of shaping data (principle 6), a gamification layer has been added to make and the learning more playful and the data crawling more interesting.

  7. A fantastic universe The story of the PERMA-DATA game (principle 5) takes place between a near future and up to the end of universe : an ideal setup for imaginating tomorrow's solutions.

  8. Art for the soul Illustrating this very universe (principle 6), creativity and aesthetics are also a support for sharing knowledge better.

  9. A philosophical tale Universe (principle 6) and art (principle 7) seres as an image/metaphor of way more abstract concepts.

  10. A tool for research Sourced and verfied [plant data], that you can contribute to enlarge by your work (principle 11).

  11. A tool for gardening Inventory your genetics, manage plants in your garden, get tips and send feedback (principle 11).

  12. A tool for communities Gardening (principle 10) is also sharing. We are giving a pleasant interface to chat and visualize tasks for your gardener crew.

  13. Collaborative development The application is open-source, ready for user and developer interactions.

  14. Implementation of shared patterns Patterns are defined not to obfuscate architecture but to define a common language, easing design exchanges and code refactoring.

Development

PERMA-DATA is built on a composite stack :

The design promotes use of code patterns to enforce a scallable architecture. Please refer to the dedicated section of this document to learn more.

Quick start

Installation

You'll have then to request @Skaant to obtain mongo credentials to provision the server/mongo/clientSecret.json file with username and password :

{
  "username": "",
  "password": ""
}

Local server

Client bundles

Every client bundle has its own npm run command :

{
  "build-home-base": "webpack --config ./webpack.config.js --output ./public/bundles/pages/home/base.js ./src/bundles/entrypoints/pages/home/base/base.js",
  "build-home-auth": "webpack --config ./webpack.config.js --output ./public/bundles/pages/home/auth.js ./src/bundles/entrypoints/pages/home/auth/auth.js",
  "build-plantId-main": "webpack --config ./webpack.config.js --output ./public/bundles/pages/plantId/main.js ./src/bundles/entrypoints/pages/plantId/main.js",
  "build-plantId-auth": "webpack --config ./webpack.config.js --output ./public/bundles/pages/plantId/auth.js ./src/bundles/entrypoints/pages/plantId/auth.js"
}

Patterns

*Section automatically generated**

mongo aggregation query

Type : PATTERN_TYPE_SERVER

Describes a mongo aggregation query as a composition of a mongo aggregation stages pipeline.

Describes a facet-specific mongo aggregation query as a multiple paralleled mongo aggregation stages pipelines.

Instances : ./server/app (...) /.aggregation.js/

_chains

handler chained processes

Type : PATTERN_TYPE_SERVER

Describes chains of promises (chain links) of types : _controllers, _dbcalls and _switches.

Occurence: In an .handler file, to order the process of answering request.

Standardizes the server lifecycle, after the middlewares, from the handler, up to the response send method.

Problem: Handlers can result in a long suit of instructions, difficult to read and to maintain.

Solution: Create an array of standard operations (_controllers, _dbcalls), meant to be conditionnally (_switches) executed to prepare the response's body.

Implementation: Composition of [_chainLinks].

Instances : ./server/app (...) /.chain.js/

_data

hard coded data

Type : PATTERN_TYPE_CLIENT

Stores static data to be bundled.

Occurence: A component, or a logic, start consuming data which must be configurable for the future.

Problem: Data and logic should be separed.

Solution: Use a _data folder and fill .json or .js files with data to be extracted.

Implementation: In the consumer folder (or higher for multiple consumers), create the _data folder and some .json files to store data. .js files should be only used when storing functions.

Instances : ./src (...) /_data/

_enum

enumeration

Type : PATTERN_TYPE_GLOBAL

Define a set of shared values.

Occurence: two or more modules will have to communicate on the same values.

Problem: the values must be from the same referencial.

Solution: define a module exposing a set of values.

Implementation: the shared values module must be located in a dedicated _enums folder.

Folder should be at the top of the consumers' common folder tree.

Instances : . (...) /.enum.js/

_middlewares

middlewares folder and files

Type : PATTERN_TYPE_SERVER

Describes middleware functions and their unique folder.

Occurence: a new middleware has to be developped/integrated.

Problem 1: Where to put this new middleware ?

Problem 2: How to enforce a common interface for middleware files ?

Solution 1: Group all the middlewares used by the server app in the same folder.

Solution 2: Define a middleware file format.

Implementation 1: The server/app/folder figures the dedicated folder for all middlewares.

Test : the .middleware files location.

_middlewares folder tree pattern

_middlewares
+-- <middleware>
|   +-- <middleware>.middleware.js

Implementation 2: all the .middleware module file expose a factory which return a middleware handler.

Test : the .middleware file format.

.middleware file code pattern

module.exports =
  () =>

    (req, res, next) => {

      // the middleware logic here ...

      next()
    }

Instances : ./server/app (...) /.middleware.js/

_pattern

code patterns

Type : PATTERN_TYPE_GLOBAL

Describes a code pattern which can be reproduced across the project.

Patterns enforce logic, files and tests standardization.

These are project's keystones.

Occurence 1: Whenever a logic is shared across the code, we have two choices :

Problem: The same way _utils does it, _pattern implements the DRY principle.

At some point a logic is repeted but it also requires a higher generality for its iterations to be specialized.

Solution 1: A standard *.pattern.js file is specified at the top root of folders shared tree which describes the logic for humans and digesters (documentor and tests).

Instances : . (...) /.pattern.js/

_routes

server routes tree

Type : PATTERN_TYPE_SERVER

Describes a recursive route and router files tree.

Occurence: a new route has to be developped.

Problem 1: 1. Where to put this new route to keep a file tree as close as the route tree ?

Problem 2: 2. How to enforce a common interface for route (and router) files ?

Solution 1: 1. Define routes tree as stated :

Solution 2: 2. Define [router] and [route] file format.

Solution 3: _routes pattern diagram

Implementation 1: contains all server's routes, ordered through :

Tests :

_routes/ folder tree pattern

_routes
+-- _routers
|   +-- <router>
|   |   +-- <router>.router.js
|   |   +-- _routers // _routers recursion ...   
|   |   +-- <handlerB>
|   |   |   +-- <handlerB>.handler.js
+-- <handlerA>
|   +-- <handlerA>.handler.js
+-- _routes.router.js

Implementation 2: a .router file exposes an express.Router() which :

Test : the .router file format.

.router file code pattern

const { Router } = require('express')

const router = Router()

router
  .use(
    '<path>',
    require('./_routers/<router>/<router>.router')
  )

router
  .put(
    '/<path>',
    require('./<handler>/<handler>.handler')
  )

module.exports = router

Implementation 3: a .handler file exposes a handler signature and return the express.res (can be encapsulated in a Promise).

Test : the .handler file format.

.handler file code pattern

module.exports =
  (req, res) => {

    // the handler logic here ...

    return res
      .send()
    // or other method
  }

Instances : ./server/app (...) /.handler.js/

_utils

utilities folder

Type : PATTERN_TYPE_GLOBAL

Define a shared logic folder.

Occurence: two or more modules use the same logic.

Problem: as the DRY principle states it, we should find a way to share the logic code between this two consumers.

This pattern adresses more the shared logic location, than the abstraction concept itself, which is more relevant to _pattern.

Solution: put the logic at the top of the consumers common path.

Implementation: the logic code folder has to be located in a dedicated _utils/ folder.

Folder should be at the top of the consumers' common folder tree.

Folder tree pattern : childrens consume the sharedLogics service.

<parent>
+-- _utils
|   +-- sharedLogic
|   |   +-- sharedLogic.js
+-- <childrenA>
|   +-- <childrenA>.js
+-- <childrenB>
|   +-- <childrenB>.js

Instances : . (...) /_utils/
