• Generating multi-brand multi-platform icons with Sketch and a Node.js script — Part #1



      TL;DR


      Using a custom build script in Node JS, it is possible to manipulate a series of Sketch files, and then, using an internal Sketch tool, automatically export their assets, to generate multiple icon libraries, for multiple platforms and different brands, that support dynamic colourisation of the assets via design tokens, and also AB testing of the assets via naming convention. Easy peasy :)


      Well, actually it’s not that easy, but it can certainly be done. This post is a detailed explanation of how we did it, and what we discovered along the way.

      The problem we were trying to solve


      At Badoo we build a dating app. Actually, multiple dating apps. For multiple platforms (iOS, Android, Mobile Web, Desktop Web), across multiple teams.

      We use hundreds of icons in our apps. Some of them are the same across different apps, some are very specific to the brands the apps reflect. The icons are continuously evolving, in sync with the evolution of the design. Sometimes completely new icons are added, while others get updated, and still others get dropped (although, they often remain in the codebase).

    • The Overview of JavaScript Frameworks: Which One to Choose for Your Project?

      Ten years ago, companies who wanted to create cross-platform projects would have to cooperate with different development teams and experts. However, 2009 has changed the game, because the developers from Nitobi (later purchased by Apache) presented Cordova – a fresh framework that was able to convert web applications into mobile systems. Linking the devices’ APIs via plugins, developers could access smartphones and tablets. Cordova is a JavaScript-based tech compatible with various platforms.

      In this guide, we will review three more JS-driven systems, look at their unique features and compare them.

    • SAPUI5 for dummies part 5: A complete step-by-step exercise

      • Tutorial


      Introduction & Recap


      In the previous blog post, we learned how to create a second level of drill-down (detail of detail) and how to interact with OData and ODataModel (v2) in order to delete a database record.


      What will be covered on this exercise


      With Part 5 of this series of blog posts, we will learn how to create a SimpleForm within a Dialog that will allow us to update the information of a Sales Order Item.


      Before updating the database order we have to check that everything typed by the user validates our constraints.


      • ODataModel: we have already used it to display server-side information about our Business Partner, Sales Order, and Sales Order Items. We’ve also used it to delete a database record. We’re now going to use it to update a record thanks to the submitChanges method or remove what we’ve done with the resetChanges method.
      • Expression Binding: an enhancement of the SAPUI5 binding syntax, which allows for providing expressions instead of custom formatter functions
      • SimpleForm: a layout that allows users to create a pixel-perfect form

    • Vue, Storybook, TypeScript—starting a new project with the best practices in mind

      • Tutorial


      (originally published on Medium)


      I like writing React code. This might be an odd introduction to a story about Vue, but you need to understand my background to understand why I’m here discussing Vue.


      I like writing React code and I hate reading it. JSX is a neat idea for assembling the pieces together fast, Material-UI is amazing solution for bootstrapping your next startup’s UI, computing CSS from JS constants allows you to be very flexible. Yet reading your old JSXs feels awful – even with scrupulous code review practices you might scratch your head not once as you try to figure the intricate nesting of the components.


      I’ve heard many things about Vue—the not so new kid on the block—and I finally decided to get my feet wet; bringing in all my mental luggage of React and Polymer (and Angular, but let’s not talk about that).

    • The ever-lasting strife of static vs dynamic typing – TypeScript won’t help

      • Translation


      When my friend and I were of school age and aspiring to become software developers, we daydreamed of designing some cool stuff together – like a game or a mega-useful app.

      I chose to learn C++ and C#, he picked JavaScript. We finished school, graduated from our universities, served in the army and started our jobs. We had a pretty busy time in industrial software engineering, with lots of different jobs and positions, and after it all started to wear on us, we recalled where it all had begun.

      Having finally got together as mature developers, we decided to work on our own project – a 2D video game. Since my friend’s domain was front-end and I was a full-stack developer, our immediate choice of development platform was an Internet browser. As I was only used to working with TypeScript when designing front-end, we thought, ok, no problem, after all, TS is just JavaScript at scale. Let’s use it and things will go smoothly. If I only knew how wrong I was! When we started discussing the project, we ran into an extensive chasm of misunderstanding between us.

    • SAPUI5 for dummies part 4: A complete step-by-step exercise

      • Tutorial


      Introduction & Recap


      In the previous blog post, we learned how to move our current application into a Master-Detail app displaying Business Partner as a list (master) and its detail information with Sale Orders inside the detail page (detail).


      What will be covered on this exercise


      With Part 4 of this series of blog posts, we will learn how to create a second drill-down page with information about the Sale Order detail and display a table of Sale Order items.


      The most important part of this exercise is to understand how to Delete (part of the CRUD operations) a Sale Order Item of a Sale Order.


      • ODataModel: we have already used it to display server-side information about our Business Partner, Order Sale. Now we’re going to use it to display Sale Order Item and delete them from the set. For this purpose, we’re going to use the remove method

      This is our main task in this exercise but it’s not the only thing we’ve done in the code. Here’s a list of the things you have to do to get to the final result:


      • Add a new route and target in the manifest.json to navigate to the BusinessPartnerSeleOrderItem page
      • Listen on the Sale Order click event and navigate to the SaleOrder detail (where we will display sale order detail and sale order items)
      • Add a FilterBar to filter the Sale Order Item’s table
      • Add a ViewSettingsDialog to sort/group Sale Order Items
      • Expand the ToProduct navigation property of a SaleOrderItem entity to display Product information into table’s rows

        Hello Habr! I'm Miloš from Badoo, and this is my first Habr post, originally published in our tech blog. Hope you like it, and please share and comment if you have any questions

        So… React, amirite???

        It appeared in the middle of the decade (plagued by the endless JavaScript framework wars), embraced the DOM, shocked everyone by mixing HTML with JavaScript and transformed the web development landscape beyond recognition.

        All those accomplishments, without even being a framework.

        Love it or hate it, React does one job really well, and that is HTML templating. Together with a great community and a healthy ecosystem, it’s not hard to see why it became one of the most popular and influential JavaScript libraries, if not the most popular one of all.

      • SAPUI5 for dummies part 3: A complete step-by-step exercise

        • Tutorial


        Introduction & Recap


        In the previous blog post, we learned how to filter, sort and group our table. This is a fundamental aspect of every CRUD application because most of the time users have to deal with hundreds of hundreds of records.


        What will be covered on this exercise


        With Part 3 of this series of blog posts, we will learn how to create a Master-Detail application leveraging the SplitApp UI control and how correctly configure the app’s manifest to handle routes and targets.


        • SplitApp: UI control that allows you to create a Master-Detail application (used as a replacement of the App control)
        • Routing: we will configure the manifest.json to correctly handle the routing of the application
        • ObjectHeader: control that enables the user to easily identify a specific object. The object header title is the key identifier of the object and additional text and icons can be used to further distinguish it from other objects
        • Navigation to a detail view and bind the element context: you will learn how to navigate and open a detail page and bind the current View (of the detail) to a new context
        • List: in the master page we will use a list to display BusinessPartner because we will have less space

        • Tutorial


        Introduction & Recap


        In the previous blog post, we started designing our application rendering a table with some Business Partner. We learned what OData protocol is, how to read an OData XML manifest, how to bind data to a Table and how to customize columns layout based on different screen resolution.


        What will be covered on this exercise


        With Part 2 of this series of blog posts, we will learn how to interact with data in our Tables and List. We will learn how to filter and sort data in a smart way.


        • Create JSONModel to handle local data
        • Set a default sizeLimit to our JSONModel
        • FilterBar: UI control that displays filters in a user-friendly manner to populate values for a query
