How to parse scrape pages? `scrape-it` has only a simple request module for making requests. That means you cannot directly parse ajax pages with it, but in general you will have those scenarios: 1. **The ajax response is in JSON format.** In this case, you can make the request directly, without needing a scraping library. 2. **The ajax response gives you HTML back.** Instead of calling the main website (e.g. example.com), pass to `scrape-it` the ajax url (e.g. `example.com/api/that-endpoint`) and you will you will be able to parse the response 3. **The ajax request is so complicated that you don't want to reverse-engineer it.** In this case, use a headless browser (e.g. Google Chrome, Electron, PhantomJS) to load the content and then use the `.scrapeHTML` method from scrape it once you get the HTML loaded on the page. ### 2. Crawling There is no fancy way to crawl pages with `scrape-it`. For simple scenarios, you can parse the list of urls from the initial page and then, using Promises, parse each page. Also, you can use a different crawler to download the website and then use the `.scrapeHTML` method to scrape the local files. ### 3. Local files Use the `.scrapeHTML` to parse the HTML read from the local files using `fs.readFile`. ## :clipboard: Example ```js const scrapeIt = require("scrape-it") // Promise interface scrapeIt("https://ionicabizau.net", { title: ".header h1" , desc: ".header h2" , avatar: { selector: ".header img" , attr: "src" } }).then(({ data, status }) => { console.log(`Status Code: ${status}`) console.log(data) }); // Async-Await (async () => { const { data } = await scrapeIt("https://ionicabizau.net", { // Fetch the articles articles: { listItem: ".article" , data: { // Get the article date and convert it into a Date object createdAt: { selector: ".date" , convert: x => new Date(x) } // Get the title , title: "a.article-title" // Nested list , tags: { listItem: ".tags > span" } // Get the content , content: { selector: ".article-content" , how: "html" } // Get attribute value of root listItem by omitting the selector , classes: { attr: "class" } } } // Fetch the blog pages , pages: { listItem: "li.page" , name: "pages" , data: { title: "a" , url: { selector: "a" , attr: "href" } } } // Fetch some other data from the page , title: ".header h1" , desc: ".header h2" , avatar: { selector: ".header img" , attr: "src" } }) console.log(data) // { articles: // [ { createdAt: Mon Mar 14 2016 00:00:00 GMT+0200 (EET), // title: 'Pi Day, Raspberry Pi and Command Line', // tags: [Object], // content: '

Please [post questions on Stack Overflow](https://stackoverflow.com/questions/ask). You can open issues with questions, as long you add a link to your Stack Overflow question. 2. For bug reports and feature requests, open issues. :bug: 3. For direct and quick help, you can [use Codementor](https://www.codementor.io/johnnyb). :rocket: ## :memo: Documentation ### `scrapeIt(url, opts, cb)` A scraping module for humans. #### Params - **String|Object** `url`: The page url or request options. - **Object** `opts`: The options passed to `scrapeHTML` method. - **Function** `cb`: The callback function. #### Return - **Promise** A promise object resolving with: - `data` (Object): The scraped data. - `$` (Function): The Cheeerio function. This may be handy to do some other manipulation on the DOM, if needed. - `response` (Object): The response object. - `body` (String): The raw body as a string. ### `scrapeIt.scrapeHTML($, opts)` Scrapes the data in the provided element. For the format of the selector, please refer to the [Selectors section of the Cheerio library](https://github.com/cheeriojs/cheerio#-selector-context-root-) #### Params - **Cheerio** `$`: The input element. - **Object** `opts`: An object containing the scraping information. If you want to scrape a list, you have to use the `listItem` selector: - `listItem` (String): The list item selector. - `data` (Object): The fields to include in the list objects: - `` (Object|String): The selector or an object containing: - `selector` (String): The selector. - `convert` (Function): An optional function to change the value. - `how` (Function|String): A function or function name to access the value. - `attr` (String): If provided, the value will be taken based on the attribute name. - `trim` (Boolean): If `false`, the value will *not* be trimmed (default: `true`). - `closest` (String): If provided, returns the first ancestor of the given element. - `eq` (Number): If provided, it will select the *nth* element. - `texteq` (Number): If provided, it will select the *nth* direct text child. Deep text child selection is not possible yet. Overwrites the `how` key. - `listItem` (Object): An object, keeping the recursive schema of the `listItem` object. This can be used to create nested lists. **Example**: ```js { articles: { listItem: ".article" , data: { createdAt: { selector: ".date" , convert: x => new Date(x) } , title: "a.article-title" , tags: { listItem: ".tags > span" } , content: { selector: ".article-content" , how: "html" } , traverseOtherNode: { selector: ".upperNode" , closest: "div" , convert: x => x.length } } } } ``` If you want to collect specific data from the page, just use the same schema used for the `data` field. **Example**: ```js { title: ".header h1" , desc: ".header h2" , avatar: { selector: ".header img" , attr: "src" } } ``` #### Return - **Object** The scraped data. ## :yum: How to contribute Have an idea? Found a bug? See [how to contribute][contributing]. ## :sparkling_heart: Support my projects I open-source almost everything I can, and I try to reply to everyone needing help using these projects. Obviously, this takes time. You can integrate and use these projects in your applications *for free*! You can even change the source code and redistribute (even resell it). However, if you get some profit from this or just want to encourage me to continue creating stuff, there are few ways you can do it: - Starring and sharing the projects you like :rocket: - [![Buy me a book][badge_amazon]][amazon]—I love books! I will remember you after years if you buy me one. :grin: :book: - [![PayPal][badge_paypal]][paypal-donations]—You can make one-time donations via PayPal. I'll probably buy a ~~coffee~~ tea. :tea: - [![Support me on Patreon][badge_patreon]][patreon]—Set up a recurring monthly donation and you will get interesting news about what I'm doing (things that I don't share with everyone). - **Bitcoin**—You can send me bitcoins at this address (or scanning the code below): `1P9BRsmazNQcuyTxEqveUsnf5CERdq35V6` ![](https://i.imgur.com/z6OQI95.png) Thanks! :heart: ## :dizzy: Where is this library used?
