The cache on the GudHub server has several different uses. Namely, a few modes of server operation use the cache differently. Each of them makes the server work a little differently.

Production Mode

The current mode is intended for the site to return cached pages. This mode is used mostly for a ready-made website. To enable this mode, open the .env file and enter:


Originally, the page has no cache, but when you open it for the first time, it generates one. That's why the first user may have to wait quite a long time for the page to be generated, but all subsequent times it will be much faster due to the cache that was obtained for the first time. After that, every time any user opens the page, that cache will be used.

SSR Mode

Due to this mode, the server do not use the existing cache. It accesses the dist folder where the built files are located and generates a new cache based on them. So, this mode is useful when you need to update the content of the page.

To use it, take the page you wanna regenerate and add ?mode=ssr in the end of it, like here:


Please note that this mode is not activated in the .env file.

The second mode works in conjunction with the previous one. This means that you need to set the production mode in .env and only then activate the current.

Image Generation

As you know, it is hard for server to work with images. If your site has a large number of images, it can take a long time to generate them. So, the server has a feature that allows you to prevent repeated image generation.

To use this feature enter the disable-images-regeneration=true string after the mode=ssr:


That is, this function can be used only in combination with the SSR mode.

Multiple SSR

When you have a large number of pages that need to be re-generated using SSR mode, it is inconvenient and time-consuming to do it one page at a time. To solve this problem, the GudHub server has a special request. It allows you to re-generate an array of pages at once.

To use this method you have to send the request to your local server that looks like this:

The request body contains two properties:

    "pages": "/news/",
    "website": "gudhub.com"
Property Name Type Description
pages string allows you to filter pages. That is, those pages that meet the conditions specified here will be re-generated. For example, you can specify a category name like /news/ or even a word that appears in the links of the desired pages
website string transfer the site whose pages will be re-generated

This request does not re-generate images that are not updated. This is because the feature described in the previous chapter is active here by default.

This mode takes pages from all sitemaps and creates an array. If the pages property is empty, it processes all pages from the sitemaps. Otherwise, it filters the pages and processes those that satisfy the conditions.

Development Mode

The last mode always returns the latest version of the site.

In this case, the cache is saved but not used.

To use this mode, open the .env and enter this here:


It is mainly used in development, but if you are using the latest version of the server, then the simplest site can be raised in this mode in production.
