![]() XCode should pick up these changes automatically and you’ll see a nice display of your icons.Īndroid is not quite as automated but works well. Images.xcassets/AppIcon.appiconĪfter parsing out the required sizes from this file, the master icon is copied into `temp_output`, copied and resized to the requisite sizes, and finally, the images and modified Contents.json are dropped into the correct iOS folder locations. You can add overlays and modifications to the staging layer group in Photoshop and the modifications will not affect the master icon export.įirst, the script reads your ‘Contents.json’ file stored in ![]() You have two groups in the .psd file, one for exporting the production icon and another for a staging / dev icon. To edit the master icon, edit this Smart Object. Basically, we’ve got two groups in Photoshop that both reference the same “Smart Object”. If you want to get really advanced you can create text files in your repo like this:ġ024x1024 master_icon.png 500x500 master_icon_500.png 200x200 master_icon_200.png 100x100 master_icon_100.pngĪnd paste them into your Photoshop layers to get a variety of sizes.Īnother slightly advanced photoshop technique. Photoshop will automatically generate this .png file at the specified resolution every time the file is saved. The idea is that by naming a layer or group like this: Photoshop includes a little-known asset generating feature that I highly recommend. If all goes according to plan, this script will quickly generate all the icons you need. “makeIcons”: “node iconGenerator/scripts/make_icons.js” ĭrop this folder into your React Native project in the root directory, run ‘npm install’ or ‘yarn’.Īdd this line to your package.json file to keep things nice and easy. When pushing these apps to beta testers it’s really great to provide unique icons to distinguish staging from production.Īfter much tedium and gnashing of teeth, I’ve built what I think is a very slick icon generator using Photoshop and the Sharp JS image processing library. Our projects often have a staging/dev version and a production version generated from the same codebase. Unfortunately, and as many of you know, the process of creating these icons is tedious and frustrating. Despite this fast-moving approach, I really don’t like to send a deliverable to a client with the icons looking like this: When we’re prototyping an app we focus on the core functions and leave most of the extras for another future milestone. With our requirements of speed and multi-platform deployment React Native is the clear choice. Much of our work is in building proof of concept and early stage apps to demonstrate the viability of new products and ideas. Node scripts/make_icons.js - for an alternate staging / dev mode iconĮdit project_name in scripts/config.js to reflect the name of your project In your Xcode project add a blank icon set: Mac/Linux users, virtually any terminal will work.A simple Javascript tool for creating, editing, generating and placing all icon assets into a cross-platform React Native project.Windows users: for the best Ionic experience, we recommend the built-in command line (cmd) or the Powershell.writing code!

Here’s the finished app running on all 3 platforms: What We'll Build Follow along as we learn the fundamentals of Ionic app development by creating a realistic app step by step. The great thing about Ionic is that with one codebase, you can build for any platform using just HTML, CSS, and JavaScript.
