Watch out for Singletons

If you are a seasoned Episerver developer, you should (and probably, already) know about the foundation of the framework: dependency injection. With the Inversion of control framework (most common, Structuremap, but recent versions of Framework Read more

Index or no index, that’s the question

If you do (and you should) care about your Episerver Commerce site performance, you probably know that database access is usually the bottleneck. Allowing SQL Server works smoothly and effectively is a very important key to the great performance. We are of course, very well aware of this fact, and we have spent a considerable amount of time making sure Commerce database works as fast as we could. Better table schema, better stored procedures, better indexes, ... we have done all of that and will continue doing so when we have the chances. (And if you find anything that can be improved, you are very welcome to share your finding with us) But there are places where the database performance improvement is in your hand. (more…)

Multiple sites: Building the outgoing URLs

In previous recipe we talked about multiple catalogs with same "UriSegment" - which we had a working implementation for incoming URL, i.e. when a customer visit a product url, we know which catalog we should choose from. But we still need to cover the generation of outgoing URL. I.e. when we link a product (For example, from a campaign page), we need to generate an URL which take the "catalog-less" pattern into account. We need to understand how the outgoing URL is built. The hierarchical router builds the URL by the RouteSegment of contents. However, we want to the urls appear to have same catalog, so the RouteSegment part for the catalogs must be the same, regardless of the true catalogs. Because all catalogs are on same level, their RouteSegment must be unique - and this is enforced from Framework level (which is understandable, otherwise, how can it know which content to choose).

Catalog

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-5b21822e56315400453650/] (more…)

Adding backslash ending to your URLs by UrlRewrite

It's generally a best practice to add a backslash to your URLs, for performance reasons (let's get back to that later in another post). There are several ways to do it, but the best/simplest way, IMO, is using UrlRewrite module. In most of the case, processing the Urls before it reaching the server code will be most effective, and here by using UrlRewrite we trust IIS to do the right thing. Our application does not even need to know about it. It's also a matter of reusable. You can simply copy a working, well tested rule to another sites without having to worry much about compatibility. Before getting started, it's worth noting that UrlRewrite is an IIS module which is not installed by default, if you want to use it, then you would have to install it explicitly. Download and install it from https://www.iis.net/downloads/microsoft/url-rewrite . And then we can simple add rules to <system.webServer><rewrite><rules> section in web.config. For the purpose of this post, this rule should be enough: [crayon-5b21822e56770476544601/] If you are new to UrlRewrite, may be it's useful to explain a bit on the rule. Here we want to add a rule which matches every url, except the urls which already end with backslash (/) already. (more…)

Package equivalent promotion type in Episerver Commerce

Recently we got this question on how to create package-equivalent promotion type in Episerver Commerce, from https://world.episerver.com/forum/developer-forum/Episerver-Commerce/Thread-Container/2018/2/is-there-a-built-in-group-discount/ I already recommended to use package for such purpose, because of several reasons:

  • Package is a builtin feature, and is fully supported by the framework, both on UI level and API level.
  • It has been well tested and is very reliable to use.
However in a real world implementation, it might not be easy to just add package implementation. One reason would be if you rely on an external PIM to handle your catalog. Configuring it to support package can not be trivial. So why not try to implement a package equivalent promotion in the promotion engine, to see if it works. (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…)

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…)

World forums support vote up/down now, and what does that mean for you

I really wanted to post this in the official blog, however we don't have a "World" blog, and this does not really fit into "Commerce blog" which we (Commerce development team) usually use for official announcements, so I have to use my personal blog instead. If you haven't noticed, then you can now vote up, or down a post in World forum. Thanks to the hard work of my colleagues in World development team, that feature went on live today! (Of which I'm very excited) If you have been using StackOverflow (as as developer, you likely have), then you know the meaning of voting up and down. The idea is the same here, there are differences in the detail implementations, such as the amount of points given (or taken) from a vote up (down), but basically: (more…)
