   • What are the pros and cons of using an HTML parsing package like html-react-parser vs dangerouslySetInnerHtml in React

     Top Answer

     Answered May 02, 2021 · 7 votes

     I've recently been studying this issue for a Headless CMS project I'm working on. From what I understand:

     dangerouslySetInnerHtml creates DOM elements outside of ReactDOM.Render() method, so it's not dynamically maintained by the React library. This basically defeats the purpose of using React in the first place (displaying and maintaining virtual DOM).

     More concerning, though, is that it's vulnerable to Cross-Site Scripting (XSS) attacks, which is where it gets its name. These are a very common form of attack on the web. You can read about that here: https://reactjs.org/docs/dom-elements.html#dangerouslysetinnerhtml

     If you want the app to be less prone to attacks, you'll have to use a sanitization library like DOMPurify for dangerouslySetInnerHtml, so you're likely to have another dependency either way. Once you compile the app for production (npm build) the minimization process makes the codebase extremely compact, and you can do some optimization beforehand with techniques like code-splitting, which makes each section of your page load only if requested, instead of all at once: https://reactjs.org/docs/code-splitting.html

     I wouldn't worry too much about a few dependencies, personally - they're a fact of life on the modern web. I've been leaning towards using html-react-parser, but I caveat that by saying I have not investigated whether it reduces XSS vulnerability. However, even if both are vulnerable to XSS attacks, at least html-react-parser introduces the elements through ReactDOM.render() so they don't make the DOM all catty-wompus - that sounds like a recipe for disaster down the road.

   • What are the actual problems of not closing tags and attributes in HTML

     Top Answer

     Answered Aug 20, 2011 · 11 votes

     You can often leave the closing tags off many elements without changing 'the way it looks'. However, even though one of the main goals of HTML5 is to standardize how browsers deal with bad markup, not closing tags can impact your content in unexpected ways. Here's a simple example, a list of items where some of the items are blank, both without explicitly closed tags and with:

     <ul> <li>Item <li> <li>Item <li> <li>Item</ul><ul> <li>Item</li> <li></li> <li>Item</li> <li></li> <li>Item</li></ul>

     Looking at the two in a browser they look identical. However, if you add a bit of CSS to hide the empty ones:

     li:empty { display: none; }

     Now they don't look the same, even though the markup hasn't changed from the previous example. The underlying reason for this is that the two versions produce different DOM trees, this version iterates through all the nodes in both lists and counts them, then shows the results and the list of nodes found in alerts. You can see the top list has 12 DOM nodes, the lower list has 15. The results are at least consistent cross browser, and the difference is in text nodes which you'll frequently skip over when scripting anyway, but this shows that even if the visual output looks the same when tags are closed or not, there are underlying differences even in an example as simple as this.

   • What are the different doctypes in html and what do they mean?

     Top Answer

     Answered Feb 26, 2021 · 54 votes

     Traditionally, a Doctype, or Document Type Declaration associates the document with a Document Type Definition.

     The Document Type Definition is a standard for a specific XML or SGML document. XML and SGML themselves doesn't have much of a schema or a very specific set of rules aside from how tags and attributes work in general. You can think of a DTD a description of the rules for a particular kind of document (like HTML, SVG or MathML). They say what tags are allowed where (e.g. that an html element must contain exactly one head element followed by exactly one body element).

     There are alternatives to DTDs such as XML Schemas that are more commonly used today.

     Browsers, however, do not use DTDs at all. They read the Doctype to determine the rendering mode, but the rules for parsing the document are entirely baked into the browser.

     This is why HTML 5 has a Doctype (to determine the rendering mode) but not DTD.

     Rendering Modes

     Early web browsers were very buggy. When new versions were released they had to maintain compatibility with their predecessors and rivals. This made it very hard to fix bugs because websites were built that depended on them.

     To resolve this, modern browsers have different rendering modes (standards mode, for rendering your document and css according to standards, and quirks mode, wherein the browser emulates the bugs of earlier browsers, and almost standards mode which sits between the two).

     Choosing a Doctype

     There are two factors to consider when selecting a Doctype:

     • Does it trigger standards mode? (For new pages it should, times when you need to be compatible with browsers which don't support standards mode are very rare today).
     • Does it support the features I need?

     Generally this means you should use HTML 5. It is the current standard and best reflects how browsers actually work:

     <!DOCTYPE html>-

     Failing that. Strict doctypes avoid most features that should be handled with CSS.

     When writing in XHTML 1.0, this Doctype is common:

     <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">-

     More obsolete features are available via:

     <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">-<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">

     When writing in HTML 4.01, this one is common instead:

     <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd">-

     With the obsolete features being in

     <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">-

     and

     <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN""http://www.w3.org/TR/html4/frameset.dtd">-

     Note that most of the above have variations (e.g. you can omit the URL and rely on the public identifier) which have implications for the support of standards mode. This article includes an extensive list.

     Debate on Strict versus Transitional Doctypes

     (Note that the following is much, must less true in 2021 than it was in 2008)

     Standards evangelists have called for web developers to stop using the Transitional Doctype on new pages and instead use Strict. Again, this is a case where the theory and the practice have some difficulties being reconciled. The original hope of the transitional Doctype was to provide a halfway house for transitioning legacy websites toward standards-compliance. With transitional doctypes, the restriction on elements and attributes is literally "less strict", so developers would be able to get their work running under standards mode sooner, and phase out the outstanding differences over time.

     Controversy exists because it isn't always quite so simple for a developer change the Doctype in an enterprise environment. Freelance developers and makers of small- or medium- sized websites may often have an easier time determining their Doctype and making this transition. In an enterprise production environment for a highly-demanded web-based service, there are inherently more complicated dependencies on legacy systems and 3rd party code products, which themselves may be on a roadmap for removal or redesign, but the execution of such changes must be done methodically and incrementally.

     Helpful Tools

     The W3C (World Wide Web Consortium) is a group which plays an active role in defining these kinds of standards. They maintain a helpful online tool at http://validator.w3.org/ for verifying and validating documents against their standards. There are many other 3rd party tools and browser extensions with similar functionality.
