About .heex Files
HEEX files are HTML+EEX files that mix static HTML with embedded Elixir code. They are plain text files with the MIME type text/html.
- Main Use: They serve as templates in the Phoenix web framework. Developers use them to build dynamic, interactive web pages.
- Embedded Code: These files allow inline Elixir code, which lets the application render real-time content.
- Editing: You can open HEEX files with text editors like Visual Studio Code, Sublime Text, or Atom that support Elixir syntax.
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 .heex file?
A .heex file stands for HTML+EEX and is a template file used in the Phoenix Framework for the Elixir programming language. It combines standard HTML structure with embedded Elixir code to create dynamic, structure-aware web pages specifically for Phoenix LiveView.
How do I open and edit a .heex file?
You can edit .heex files with any advanced text editor. For the best experience, use Visual Studio Code with the official ElixirLS extension, or Sublime Text, as these provide syntax highlighting for both the HTML and the embedded Elixir code.
What is the difference between .eex and .heex?
While both are templating formats for Elixir, .eex is general-purpose text generation, whereas .heex is HTML-aware. This means .heex templates validate your HTML tags (checking for proper nesting and closing tags) during compilation, which helps prevent errors in web applications.
Can I convert a .heex file to standard .html?
You cannot simply "convert" a .heex file to HTML using a file converter because it contains server-side logic that must be executed. The Phoenix server compiles the .heex file into standard HTML dynamically when a user requests the page. If you just rename the file to .html, the code inside <% ... %> tags will be displayed as raw text.
Why can't I view my .heex file in a web browser?
Web browsers like Chrome or Firefox do not understand Elixir code. To view the file as a webpage, you must run the associated Phoenix application server, which processes the template and serves the result as a standard text/html document to the browser.
What is the MIME type for .heex files?
Although .heex files are source code templates, they are text-based and eventually render content with the MIME type text/html. When configuring a web server or editor associations, they are often treated as plain text or specifically associated with Elixir development tools.
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.
