React Tutorial: A Comprehensive Guide to learning React.js in 2018

  • These components are defined either in pure JavaScript or they can be defined in what the React team calls “JSX”.
  • The reason the React team went with this approach is because, since the virtual DOM is a JavaScript representation of the actual DOM, React can keep track of the difference between the current virtual DOM(computed after some data changes), with the previous virtual DOM (computed befores some data changes).
  • In more layman’s terms, because manipulating the actual DOM is slow, React is able to minimize manipulations to the actual DOM by keeping track of a virtual DOM and only updating the real DOM when necessary and with only the necessary changes.
  • The process looks something like this, – – Some user event which changes the state of your app → Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.
  • Signal to notify our app some data has changed→ Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.

Atomic design, Angular 2 and Redux – Lieuwe van Brug – Medium

Atomic design, Angular 2 and Redux  #angular #webdevelopment #redux #design #reactjs

  • How do you setup the frontend to be quick in prototyping?As a ux’er, you probably heard of Brad Frost and his idea of Atomic Design.
  • It’s basically a design system to divide your frontend into components.
  • And because it is a ux design system, communicating with the ux’er is very easy.
  • When an event is needed in one of the components, it just fires it to the Redux store, the centralised state is updated and all subscribed components are updated afterwards.
  • In my experience, atoms and molecule level for the input/output system and the organisms and templates to the redux store.

A match made in heaven. Last year I got the change to start a whole new product in the rol of frontend architect & developer. The starting team was only a product owner, ux’er and myself to start off…

WorkflowGen version 7.0 – WorkflowGen – Medium

WorkflowGen version 7.0  #webhooks #nodejs #softwaredevelopment #releasenotes #reactjs

  • WorkflowGen’s SENDHTTPPOST application enables process designers to create outgoing webhooks via system actions in workflows.
  • Webhooks are another modern integration solution that let WorkflowGen processes exchange information with other applications through HTTP POST requests.
  • With version 7.0, WorkflowGen now supports incoming webhooks as well, which can be sent from external applications to WorkflowGen by exchanging JSON payloads using HTTP POST requests.
  • With version 7.0, WorkflowGen has adopted GraphQL for its new API, as well as modules for both incoming and outgoing webhooks, creating exciting new avenues for integration.
  • Outgoing webhooks , introduced in WorkflowGen 6.6, are a simple way to send HTTP POST requests to external applications, such as to post a message to a Slack channel .

With version 7.0, WorkflowGen has adopted GraphQL for its new API, as well as modules for both incoming and outgoing webhooks, creating exciting new avenues for integration. WorkflowGen is already a…

Using React and Redux to Create a Mapping Plugin

How to use @reactjs and Redux to create a #mapping plugin

  • Map services in the layer selector are represented by an immutable tree structure, populated from a static JSON configuration file.
  • Regional Planning is one such plugin created by Azavea for the GeositeFramework.
  • done(function(data) { serviceData.set(serviceUrl, data); redraw(); });
  • The article presents a high level technical overview for the implementation of the Regional Planning plugin for the Coastal Resilience GeositeFramework .
  • We were able to translate our knowledge of React design patterns and best practices to develop the Regional Planning plugin for the GeositeFramework.

Lessons learned from our experience with React and Redux to create the Regional Planning plugin for the Coastal Resilience GeositeFramework.
