How to develop Shopify themes locally?
As of 2020, Shopify has stopped support Slate so you can now use Themekit - https://shopify.github.io/themekit/
There are quite a few workflows you can use here.
1. Task runners
If you're using either Gulp or Grunt locally for development, there are libraries out there that will upload your files to the store through API credentials of a Private App that you have to create. Most work by uploading the files you change, using a watcher.
- grunt-shopify
- grunt-shopify-upload
- gulp-shopify-upload (it's my favourite since I use Gulp but has a known issue that sometimes it stops uploading files and you have to restart it).
2. Official Shopify Theme Kit
Theme Kit is a cross-platform CLI tool that was built by Shopify Employees. It can run on windows/linux/OS X. You can read more about it on Shopify Blog or download it directly. The alternative previously mentioned of Desktop Theme Editor is deprecated and has been replaced by Theme Kit.
3. Third-party SaaS Applications
Instead of watching for changes, these will work with a continuos integration workflow, where your latest push on a certain branch gets uploaded to the theme you've selected.
- Beanstalk. More specific information can be found on their landing page for Shopify, here.
- DeployBot. Their help article on Shopify has some information on how to get started. Both options are from the same company. Here's a comparison of both they've did on their blog.
4. Third-party libraries
There's also an alternative not officially supported by Shopify which is a TextMate Bundle in case you use that OSX editor.
There's an unofficial extended cli similar to theme kit but with further functionality called Quickshot, which I've just found out based on Matt's response and seems pretty awesome. Some of the features they highlight are:
- Supports uploading to multiple Shopify stores and themes
- Easy to use configuration wizard
- Uploads/downloads in parallel greatly reducing transfer times
- Supports autocompiling scss locally before uploading to Shopify
- Supports autocompiling Babel/ES6 into modules which are easily used by - Requirejs and others
- Can use with .gitignore files or a custom .quickshotignore file.
- Can download/upload Shopify Blogs, Pages and Products! Easily transfer them between stores! Even the metafields! And edit them locally in your favorite editor.
Shopify recently released Slate, a new tool for theme development.
