Svg minify1/8/2024 ![]() ![]() Filestack’s file picker allows users to strip the exif data on the client side, allowing for a secure upload, every time. Setting the strip parameter to true removes embedded metadata at the source, purging malicious code hidden within. Users with additional security needs can use another boolean parameter called strip. Sanitizing SVG and HTML files helps prevent cross-site scripting (XSS) attacks. Filestack users can implement a variety of parameters to remove insecure tags. The secure parameter is a boolean parameter that when set to true, will detect and strip these insecure tags from the SVG or HTML file. This process, called HTML sanitization, will not affect most basic formatting tags, but will remove complex tags that run scripts, call objects, embed files, or link to potentially dangerous sites. Malicious code is often stored in the form of tags. If a user uploads or delivers an infected SVG or HTML file, the virus has the potential to execute and spread to recipient files. If the user agrees to the installation, their login credentials, credit card information, and other sensitive data may fall into the wrong hands. These sites often prompt users to install spyware disguised as a browser plugin or, ironically, a virus detection program. For example, an infected SVG file can redirect users to a malicious website disguised as a reputable one. SVG files can also contain embedded JavaScript (JS) code, a potential vulnerability. At their core, SVG files are no different than standard plain text documents that provide instructions on how to display text, colors, shapes, and other graphical elements. Interactions.SVG files are vector graphics based on XML. Use the type="module" attribute as described above to enable importing other modules from an inline script. and tags with text content are also processed just like standalone files, and the generated bundles are inserted back into the SVG file. ![]() Įxternal resources referenced via the url() function in presentation attributes such as fill, stroke, clip-path, and many others are also supported. ![]() Parcel supports external references via the href and xlink:href attributes on many other elements. Bundle naming can be overridden by Namer plugins. That's because these URLs are typically human readable, and need to have a stable name over time. While other assets referenced from an SVG file will include a content hash in their compiled filename by default, files referenced by an element will not. Parcel supports the href and xlink:href attributes. SVG files can link to other web pages or files using the element. See the Image docs for details on how Parcel processes images. Note: SVGs referenced via the element do not load external resources such as stylesheets, fonts, and other images, and scripting and interactivity is disabled. You can reference a CSS file, or any other file that compiles to CSS such as SASS, Less, or Stylus. Stylesheets #Įxternal stylesheets can be referenced via the xml-stylesheet processing instruction in an SVG document. These references are rewritten so that they link to the correct output files.įile names are resolved relative to the current SVG file, but you can also use absolute and tilde specifiers. Parcel detects most references in SVG to other files (such as, , and ) and processes them as well. Parcel includes support for SVG as a separate file, embedded in HTML, or imported as JSX in a JavaScript file. SVG is a vector-based 2D graphics format based on XML, with support for interactivity and animation.
