And this affects all the way we write code for Drupal 8, be it a custom module for your project or a contributed module that you want to publish on drupal.org Let us dive into the details and learn how to write a custom module for Drupal 8! In this first article of the ‘Drupal 8: Writing your first Drupal 8 custom module’ series, we will explore the details of the info.yml file.   ## The info file With slight modifications, the info file is almost identical to previous versions of Drupal. However, in Drupal 8, it is known as *info.yml* and a few extra parameters/instructions/routines for Drupal 8 In Drupal 8, info.yml file takes following details/routines: type\*: Is this a module or theme or even a distribution/profile? Allowed values: *string module|theme|profile* name\*: Name of your custom module/theme/distribution/profile Allowed value: *string \[A human readable name which will be displayed on Modules list page\]* GeoBlocker description\*: some descriptive text about your custom code. Allowed value: *string \[details about what your module offers\]* core\*: What Drupal core version this custom code targets. Allowed value: *8.x* (Post Drupal core 8.8, this routine is no longer required) package: In what group you want to put this custom code in. If you do not specify this routine, Drupal puts your custom code under ‘others’ on modules list page. Allowed value: *string* Geo core\_version\_requirements: Specifically used to denote that your custom code/module is compatible with Drupal 9 and can be used on a Drupal 9 website without modifying code.   Allowed value: *^8 || ^9* configure: If your module offers a configuration page, you need to provide reference to relative path to the configuration page here, as in your routing.yml file. *\* required routine*   Here is an example of actual Drupal 8 / 9 module info.yml file ``` type: module name: GeoBlocker     description: "Restricts or allows access to the website, or to a subset of nodes, in regards of user's country of origin." configure: geoblocker.configuration_form package: Geo core_version_requirement: ^8.8 || ^9 ``` ![Durpal 8 custom module -- Info file | Joshi Consultancy Services](https://e.joshics.in/hubfs/Imported_Blog_Media/Drupal-custom-module-info-file.png) [Drupal Planet](https://e.joshics.in/blog/tag/drupal-planet), [Drupal](https://e.joshics.in/blog/tag/drupal), [Drupal 9](https://e.joshics.in/blog/tag/drupal-9), [Drupal 8](https://e.joshics.in/blog/tag/drupal-8) ## Related posts [![](https://e.joshics.in/hs-fs/hubfs/Imported_Blog_Media/JOSHI-30072020-filled-background-Sep-16-2021-11-58-28-53-AM.png?height=200&name=JOSHI-30072020-filled-background-Sep-16-2021-11-58-28-53-AM.png)](https://e.joshics.in/blog/drupal-8-migration-drush-commands) [Drupal Planet](https://e.joshics.in/blog/tag/drupal-planet), [Drupal](https://e.joshics.in/blog/tag/drupal), [Drupal 8](https://e.joshics.in/blog/tag/drupal-8) ## [Drupal 8 Migration Drush commands](https://e.joshics.in/blog/drupal-8-migration-drush-commands) [Bhavin Joshi](https://e.joshics.in/blog/author/bhavin-joshi) Sep 16, 2020 5:27:45 PM Drupal 8 migration is always painful if not planned well.
