Which MIME types are related to file extension ".psgi"?
The .psgi file extension is associated with 1 MIME types:
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .psgi Files
PSGI files are text files written in Perl that follow the Perl Server Gateway Interface standard.
They act as a bridge between web servers and Perl web applications and carry the MIME type text/x-perl.
These files contain code that defines how web requests and responses are managed on a server.
- Main use case: Running web applications by providing a standardized interface between the web server and the application logic.
- Other uses: Configuring server settings and testing web app components.
- Software: They are run using Perl interpreters and PSGI-compatible servers like Plack or Starman. You can view and edit them using any text editor (e.g., Notepad, Sublime Text, or VSCode).
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .psgi file?
A .psgi file is a source code file written in Perl that adheres to the Perl Server Gateway Interface specification. It serves as a standard interface between web servers and Perl web frameworks (like Catalyst or Dancer), allowing the application to run on various server environments without code changes.
How do I open and edit a .psgi file?
Since .psgi files contain plain text source code, you can open them with any text editor. Popular choices for developers include Visual Studio Code, Sublime Text, Notepad++, or Vim. While you can use basic tools like Notepad, code editors provide syntax highlighting that makes reading Perl code easier.
How do I run a .psgi file?
You cannot double-click a .psgi file to run it like a program; it requires a PSGI-compatible server runner. The most common tool is plackup (part of the Plack toolkit), which launches a local web server using the instructions in the file. Production environments often use high-performance servers like Starman.
What is the MIME type for .psgi files?
PSGI files are typically associated with the MIME type text/x-perl because they are fundamentally Perl scripts. While they are executed on the server rather than served to the public, this media type helps editors and systems recognize the content as Perl code.
Why does my browser display the .psgi code instead of the website?
If you see raw code in your browser, your web server (e.g., Apache or Nginx) is not configured to execute the file. You must configure the server to proxy requests to an application server running the .psgi file, rather than serving the file itself as static content.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
