PowerShell module

A PowerShell module is a .psm1 file (a script module that contains any valid Windows PowerShell code) that contains PowerShell logic. A module manifest is? a PowerShell data file (.psd1) that describes the contents of a module and determines how much a module is processed. Its main purpose is to allow the standardization (ie, reuse and abstraction) of Windows PowerShell code.

Are you aware that a module is made up of four basic components? They are;

• Some sort of code file - usually either a PowerShell script or a managed cmdlet assembly.
• Anything else that the above code file may need, such as additional assemblies, help files, or scripts.
• A manifest file that describes the above files, as well as stores metadata such as author and versioning information.
• A directory that contains all of the above content, and is located where PowerShell can reasonably find it.

Script Module: Script module is a file (.psm1) that contains any valid Windows PowerShell code. A script module is simply a Windows PowerShell script with a different extension, which allows administrators to use import, export, and management functions on it. It needs to be saved in a folder that PowerShell can reasonably discover.

Binary Module: A binary module is a .NET Framework assembly (.dll) that contains compiled code, such as C#. A binary module allows you to create cmdlets that are faster or use features (such as multithreading) that are not as easy to code in Windows PowerShell scripts.

Did you know that a PowerShell-based bot framework for ChatOps. PowerShell modules are loaded into PoshBot and instantly become available as bot commands? PoshBot currently supports connecting to Slack to provide you with awesome ChatOps goodness. Bot commands can optionally be secured via permissions, roles, and groups to control who can execute what.

PowerShell manifest

A?module manifest is a?.psd1?file that contains a hash table.

• It creates a manifest that includes all the commonly used manifest keys, so you can use the default output as a manifest template.
• It also helps to add or change values, or to add module keys that this cmdlet doesn't add, open the resulting file in a text editor.
• Modules can reference script files (.ps1), script module files (.psm1), manifest files (.psd1), formatting and type files (.ps1xml), cmdlet, provide assemblies (.dll), resource files, help files, localization files, or any other type of file or resource that is bundled as part of the module.
• For an internationalized script, the module folder also contains a set of message catalog files. If you add a manifest file to the module folder, you can reference the multiple files as a single unit by referencing the manifest.
