What is vfile-message?

The vfile-message npm package is designed for creating and managing virtual file messages, such as warnings and errors, in a standardized format. It is commonly used in file processing pipelines to report issues found during the processing of files. These messages can include details such as the position of the issue within the file, the rule that was violated, and a human-readable message describing the problem.

What are vfile-message's main functionalities?

Creating a new message

This code demonstrates how to create a new vfile message. The message includes a human-readable string, a position object indicating where in the file the message applies, and an optional error code.

{"const VFileMessage = require('vfile-message');\nconst message = new VFileMessage('This is an error message', {line: 10, column: 5}, 'error-code');\nconsole.log(message);"}

Associating a message with a file

This example shows how to create a vfile message and associate it with a vfile. The message is pushed into the file's `messages` array, allowing multiple messages to be associated with a single file.

{"const vfile = require('vfile');\nconst VFileMessage = require('vfile-message');\nconst file = vfile();\nconst error = new VFileMessage('Invalid syntax', {line: 2, column: 10}, 'syntax-error');\nfile.messages.push(error);\nconsole.log(file.messages);"}
