海外TECH	DEV Community	How web browsers work - parsing the HTML (part 3, with illustrations)📜🔥	https://dev.to/arikaturika/how-web-browsers-work-parsing-the-html-part-3-with-illustrations-45fi	How web browsers work parsing the HTML part with illustrations Until now we discussed navigation and data fetching Today we re going to talk about parsing in general and HTML parsing in particular We saw how after the initial request to the server the browser receives a response containing the HTML resources of the webpage we are trying to access the first chunk of data Now the job of the browswer will be to start parsing the data Parsing means analyzing and converting a program into an internal format that a runtime environment can actually run In other words parsing means taking the code we write as text HTML CSS and transform it into something that the browser can work with The parsing will be done by the browser engine not to be confused with the the Javascript engine of the browser The browser engine is a core component of every major browser and it s main role is to combine structure HTML and style CSS so it can draw the web page on our screens It is also responsible to find out which pieces of code are interactive We should not think about it like a separate piece of software but as being part of a bigger sofware in our case the browser There are many browser engines in the wild but the majority of the browsers use one of these three actively developed full engines Gecko It was developed by Mozilla for Firefox In the past it used to power several other browsers but at the moment besides Firefox Tor and Waterfox are the only ones still using Gecko It is written in C and JavaScript and since additionally in Rust WebKit It s primarily developed by Apple for Safari It also powers GNOME Web Epiphany and Otter surprinsingly enough on iOS all browsers including Firefox and Chrome are also powered by WebKit It it written in C Blink part of ChromiumBeginning as a fork of WebKit it s primarily developed by Google for Chrome It also powers Edge Brave Silk Vivaldi Opera and most other browser projects some via QtWebEngine It is written in C Now that we understand who s going to do the parsing let s see what happens exactly after we receive the first HTML document from the server Let s assume the document looks like this lt doctype HTML gt lt html gt lt head gt lt title gt This is my page lt title gt lt meta charset UTF gt lt meta name viewport content width device width initial scale gt lt head gt lt body gt lt h gt This is my page lt h gt lt h gt This is a H header lt h gt lt p gt This is a paragraph lt p gt lt p gt This is another paragraph lt p gt lt body gt lt html gt Even if the request page s HTML is larger than the initial KB packet the browser will begin parsing and attempting to render an experience based on the data it has HTML parsing involves two steps tokenization and tree construction building something called the DOM Tree Document Object Model TokenizationIt is the lexical analysis and it converts some input into tokens basic components of source code Imagine we would take an English text and break it down into words where the words would be the tokens What results at the end of the tokenization process is a series of zero or more of the following tokens DOCTYPE start tag lt tag gt end tag lt tag gt self closing tag lt tag gt attribute names values comments characters end of file or plain text content within an element Building the DOMAfter the first token gets created tree building starts This is essentially creating a tree like structure called the Document Object Model based on the previously parsed tokens The DOM tree describes the content of the HTML document The lt html gt element is the first tag and root node of the document tree The tree reflects the relationships and hierarchies between different tags We have parent nodes and tags nested within other tags are child nodes The greater the number of nodes the longer it will takes to build the DOM tree Below is the DOM Tree for the HTML document example we got from the server In reality the DOM is more complex than what we see in that schema but I kept it simple for a better undestanding also we ll talk in more detail about the DOM and its importance in a future article This building stage is reentrant meaning that while one token is handled the tokenizer might be resumed causing further tokens to be emitted and processed before the first token s processing is complete From bytes until the DOM is created the complete process would look like something like this The parser works line by line from top to bottom When the parser will encounter non blocking resources for example images the browser will request those images from the server and continue parsing On the other hand if it encounters blocking resources CSS stylesheets Javascrpt files added in the lt head gt section of the HTML or fonts added from a CDN the parser will stop execution until all those blocking resources are downloaded That s why if yu re working with Javascript it is recommended to add your lt script gt tags at the end of the HTML file or if you want to keep them in the lt head gt tag you should add to them the defer or async attribute async allows for asynchronous as soon as the script is downloaded and defer allows execution only after the whole document has been parsed Pre loaders and making the page fasterInternet Explorer WebKit and Mozilla all implemented pre loaders in as a way of dealing with blocking resources especially scripts we said earlier that when encountering a script tag the HTML parsing would stop until the script is downloaded and executed With a pre loader when the browser is stuck on a script a second ligher parser is scanning the HTML for resources that need to be retrieved stylesheets scripts etc The pre loader then starts retrieving these resources in the background with the aim that by the time the main HTML parser reaches them they may have already been downloaded in case these resources were already cached this step is skipped	2022-04-25 16:23:20
