Technical Solutions for Safely Rendering Newline Characters in VueJS: Using <pre> Element and CSS white-space Property
This article explores technical solutions for safely rendering text containing newline characters in VueJS applications. Addressing the display needs of multiline text input by users, which includes newline characters (\n) when saved, traditional methods using filters to replace newlines with <br> tags pose XSS security risks. The article proposes using the HTML <pre> element as the core solution, as it natively preserves whitespace characters (including newlines) without manual conversion. Additionally, as supplementary approaches, it introduces the CSS white-space property (e.g., pre, pre-wrap, pre-line) to control whitespace handling, avoiding unnecessary style inheritance from <pre>. Through comparative analysis, the article emphasizes balancing functional requirements with security when rendering user-generated content, providing developers with safe and efficient implementation guidelines.
