Debuging React tests with Visual Studio Code

Visual Studio Code is awesome and it is getting more and more popular in front end development. It’s great to write code, but you know what, it can be an IDE and allow you to debug your tests as well: Go to Debug/Add Configuration menu and add this setting: [crayon-5ac3c27cc26d3675072325/] Read more

Multiple catalogs with same url

This is an excerpt from my second book . The first chapter is available to read for free. A business is having an Episerver Commerce instance with multiple sites and multiple catalogs set up. They want to make sure each site will use one catalog, and all of them will share the same url for catalog structure. So it'll be "https://site-a.com/products/category/", and "https://site-b.com/products/category/". Site A and site B are using different catalogs. Is this doable? Yes! It's just a matter of magic with the routing. This time, we would need to do an implementation of HierarchicalCatalogPartialRouter ourselves. First, let's create a template for it: [crayon-5ac3c27cc324b015971065/] (more…)

Speed up your Catalog incremental indexing

As your products are being constantly updated, you would naturally want them to be properly (and timely) indexed - as that's crucial to have the search results that would influence your customers into buying stuffs. For example, if you just drop the prices of your products , you would want those products to appear in new price segment as soon as possible. This should be very easy with Find.Commerce - so if you are using Find (which you should) - stop reading, nothing for you here. Things, however, can be more complicated if you are using the more "traditional" SearchProvider. (more…)

Fixing Cannot find module ‘sync-exec’ error with yarn install

Error message:
clientResources\node_modules\uglifyjs-webpack-plugin: Command failed. Cannot find module 'sync-exec'
Reason:
uglifyjs-webpack-plugin 0.4.6 defines this command 
"postinstall": "node lib/post_install.js"
which looks like this
[crayon-5ac3c27cc3d3e473131165/] So if your node instance is older than 0.10, it will fallback to require sync-exec . Unlike execSync which is a builtin module, sync-exec is, or was an old module that you have to install explicitly. If your node instance does not have that installed, boom! (more…)

Why you should upgrade to the latest version

I made no secret that I'm a die-hard advocate for upgrading to latest EPiServer CMS/Commerce version. There are several reasons for that, mostly from new shiny features that your businesses dearly need, new big performance improvements that your customers firmly demand. But there is another, not so obvious reason: support. Let me tell you a story. This morning we received a support case from support team. A customer recently upgraded from Commerce 7.5 (Eww) to 11.7 (Yay!), things went well except they had a small problem with data displaying in Catalog UI. Some of the properties were not properly displayed, but they are still showing correct in Commerce Manager. (more…)

ServiceAPI + Postman, a match in heaven

No, it's just a note-to-self. A lot of customers have been using ServiceAPI, and to great successes. We also have very good documentation here - of which largely thanks to my colleague Mark Hall. But what if you want to play around with ServiceAPI and don't want to write app/build/run it yourself? The answer is simple: There are many REST Clients can do the job for you, and Postman is usually regarded as the best/most popular one. But, the documentation are for C# client, it can be quite confusing to use Postman to work with ServiceAPI for the first time (or times). If you are experienced with Postman, great! But if you are not - like me - when you use Postman from time to time and everytime it's new, then this post can be useful to you. Today I need to do some tests with ServiceAPI, and I had to spend some time figuring out how to use Postman - so I decided it's better to have all of those noted for future reference. (more…)

Choose your battles

This is the third part of the series: How to survive and thrive - a series for new developers to become better at their jobs. You can read the first two parts here and here. In military, there is a term of "uphill battle". That when you have to fight your way up a hill, when you enemy controls the top. It's a very difficult fight and your chance of success is low. Any experienced military leader knows uphill battles are something you should avoid until there are no other options. That also applies with any jobs. Including programming. The truth is, you shouldn't fight the battles you can't win. (more…)

Mass update catalog entries

This is something you don't do daily, but you will probably need one day, so it might come in handy. Recently we got a question on how to update the code of all entries in the catalog. This is interesting, because even thought you don't update the codes that often (if at all, as the code is the identity to identify the entries with external system, such as ERPs or PIMs), it raises a question on how to do mass update on catalog entries.

    • Update the code directly via database query. It is supposedly the fastest to do such thing. If you have been following my posts closely, you must be familiar with my note regarding how Episerver does not disclose the database schema. I list it here because it's an option, but not the good one. It easily goes wrong (and cause catastrophes), you have to deal with versions and cache, and those can be hairy to get right. Direct data manipulation should be only used as the last resort when no other option is available.
