# JobsDB Scraper (`morrispetris/web-scraper`) Actor Crawls arbitrary websites using a web browser and extracts structured data from web pages using a provided JavaScript function. The Actor supports both recursive crawling and lists of URLs, and automatically manages concurrency for maximum performance. - **URL**: https://apify.com/morrispetris/web-scraper.md - **Developed by:** [petris morris](https://apify.com/morrispetris) (community) - **Categories:** Jobs, Open source - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, 0 bookmarks - **User rating**: No ratings yet ## Pricing Pay per usage This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have. Learn more: https://docs.apify.com/platform/actors/running/actors-in-store#pay-per-usage ## What's an Apify Actor? Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. - **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use). - **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`. - **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`. - **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`. - **Any other language** — the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## JobsDB Scraper Scrape job search results from JobsDB Hong Kong. ### Features - JobsDB Hong Kong - Chrome/Puppeteer - Apify Proxy - Hong Kong residential proxies - Custom job search URLs - Structured JSON output ### Input Explain the available input fields. ### Output Example: { "totalJobCount": 32824, "page": 1, "pageSize": 30, "sortMode": "RELEVANCE", "workTypes": \[ "FULL\_TIME", "PART\_TIME", "CONTRACT", "CASUAL" ] } ### Example Explain how users configure a JobsDB search. ### Proxy Explain why the Actor uses Apify Proxy. ### Limitations Explain that JobsDB may change its website and that scraping availability can change. # Actor input Schema ## `runMode` (type: `string`): This property indicates the scraper's mode of operation. In DEVELOPMENT mode, the scraper ignores page timeouts, doesn't use sessionPool, opens pages one by one and enables debugging via Chrome DevTools. Open the live view tab or the container URL to access the debugger. Further debugging options can be configured in the Advanced configuration section. PRODUCTION mode disables debugging and enables timeouts and concurrency.

For details, see Run mode in README. ## `startUrls` (type: `array`): A static list of URLs to scrape.

For details, see Start URLs in README. ## `keepUrlFragments` (type: `boolean`): Indicates that URL fragments (e.g. http://example.com#fragment) should be included when checking whether a URL has already been visited or not. Typically, URL fragments are used for page navigation only and therefore they should be ignored, as they don't identify separate pages. However, some single-page websites use URL fragments to display different pages; in such a case, this option should be enabled. ## `respectRobotsTxtFile` (type: `boolean`): If enabled, the crawler will consult the robots.txt file for the target website before crawling each page. At the moment, the crawler does not use any specific user agent identifier. The crawl-delay directive is also not supported yet. ## `linkSelector` (type: `string`): A CSS selector saying which links on the page (\ elements with href attribute) shall be followed and added to the request queue. To filter the links added to the queue, use the Pseudo-URLs and/or Glob patterns setting.

If Link selector is empty, the page links are ignored.

For details, see Link selector in README. ## `globs` (type: `array`): Glob patterns to match links in the page that you want to enqueue. Combine with Link selector to tell the scraper where to find links. Omitting the Glob patterns will cause the scraper to enqueue all links matched by the Link selector. ## `pseudoUrls` (type: `array`): Specifies what kind of URLs found by Link selector should be added to the request queue. A pseudo-URL is a URL with regular expressions enclosed in \[] brackets, e.g. http://www.example.com/\[.\*].

If Pseudo-URLs are omitted, the Actor enqueues all links matched by the Link selector.

For details, see Pseudo-URLs in README. ## `excludes` (type: `array`): Glob patterns to match links in the page that you want to exclude from being enqueued. ## `pageFunction` (type: `string`): JavaScript (ES6) function that is executed in the context of every page loaded in the Chrome browser. Use it to scrape data from the page, perform actions or add new URLs to the request queue.

For details, see Page function in README. ## `injectJQuery` (type: `boolean`): If enabled, the scraper will inject the jQuery library into every web page loaded, before Page function is invoked. Note that the jQuery object ($) will not be registered into global namespace in order to avoid conflicts with libraries used by the web page. It can only be accessed through context.jQuery in Page function. ## `proxyConfiguration` (type: `object`): Specifies proxy servers that will be used by the scraper in order to hide its origin.

For details, see Proxy configuration in README. ## `proxyRotation` (type: `string`): This property indicates the strategy of proxy rotation and can only be used in conjunction with Apify Proxy. The recommended setting automatically picks the best proxies from your available pool and rotates them evenly, discarding proxies that become blocked or unresponsive. If this strategy does not work for you for any reason, you may configure the scraper to either use a new proxy for each request, or to use one proxy as long as possible, until the proxy fails. IMPORTANT: This setting will only use your available Apify Proxy pool, so if you don't have enough proxies for a given task, no rotation setting will produce satisfactory results. ## `sessionPoolName` (type: `string`): Use only english alphanumeric characters dashes and underscores. A session is a representation of a user. It has it's own IP and cookies which are then used together to emulate a real user. Usage of the sessions is controlled by the Proxy rotation option. By providing a session pool name, you enable sharing of those sessions across multiple Actor runs. This is very useful when you need specific cookies for accessing the websites or when a lot of your proxies are already blocked. Instead of trying randomly, a list of working sessions will be saved and a new Actor run can reuse those sessions. Note that the IP lock on sessions expires after 24 hours, unless the session is used again in that window. ## `initialCookies` (type: `array`): A JSON array with cookies that will be set to every Chrome browser tab opened before loading the page, in the format accepted by Puppeteer's Page.setCookie() function. This option is useful for transferring a logged-in session from an external web browser. ## `useChrome` (type: `boolean`): If enabled, the scraper will use a real Chrome browser instead of Chromium bundled with Puppeteer. This option may help bypass certain anti-scraping protections, but might make the scraper unstable. Use at your own risk 🙂 ## `headless` (type: `boolean`): By default, browsers run in headless mode. You can toggle this off to run them in headful mode, which can help with certain rare anti-scraping protections but is slower and more costly. ## `ignoreSslErrors` (type: `boolean`): If enabled, the scraper will ignore SSL/TLS certificate errors. Use at your own risk. ## `ignoreCorsAndCsp` (type: `boolean`): If enabled, the scraper will ignore Content Security Policy (CSP) and Cross-Origin Resource Sharing (CORS) settings of visited pages and requested domains. This enables you to freely use XHR/Fetch to make HTTP requests from Page function. ## `downloadMedia` (type: `boolean`): If enabled, the scraper will download media such as images, fonts, videos and sound files, as usual. Disabling this option might speed up the scrape, but certain websites could stop working correctly. ## `downloadCss` (type: `boolean`): If enabled, the scraper will download CSS files with stylesheets, as usual. Disabling this option may speed up the scrape, but certain websites could stop working correctly, and the live view will not look as cool. ## `maxRequestRetries` (type: `integer`): The maximum number of times the scraper will retry to load each web page on error, in case of a page load error or an exception thrown by Page function.

If set to 0, the page will be considered failed right after the first error. ## `maxPagesPerCrawl` (type: `integer`): The maximum number of pages that the scraper will load. The scraper will stop when this limit is reached. It's always a good idea to set this limit in order to prevent excess platform usage for misconfigured scrapers. Note that the actual number of pages loaded might be slightly higher than this value.

If set to 0, there is no limit. ## `maxResultsPerCrawl` (type: `integer`): The maximum number of records that will be saved to the resulting dataset. The scraper will stop when this limit is reached.

If set to 0, there is no limit. ## `maxCrawlingDepth` (type: `integer`): Specifies how many links away from Start URLs the scraper will descend. This value is a safeguard against infinite crawling depths for misconfigured scrapers. Note that pages added using context.enqueuePage() in Page function are not subject to the maximum depth constraint.

If set to 0, there is no limit. To crawl only the pages specified by the Start URLs, set linkSelector empty instead. ## `maxConcurrency` (type: `integer`): Specified the maximum number of pages that can be processed by the scraper in parallel. The scraper automatically increases and decreases concurrency based on available system resources. This option enables you to set an upper limit, for example to reduce the load on a target web server. ## `pageLoadTimeoutSecs` (type: `integer`): The maximum amount of time the scraper will wait for a web page to load, in seconds. If the web page does not load in this timeframe, it is considered to have failed and will be retried (subject to Max page retries), similarly as with other page load errors. ## `pageFunctionTimeoutSecs` (type: `integer`): The maximum amount of time the scraper will wait for Page function to execute, in seconds. It's a good idea to set this limit, to ensure that unexpected behavior in page function will not get the scraper stuck. ## `waitUntil` (type: `array`): Contains a JSON array with names of page events to wait, before considering a web page fully loaded. The scraper will wait until all of the events are triggered in the web page before executing Page function. Available events are domcontentloaded, load, networkidle2 and networkidle0.

For details, see waitUntil option in Puppeteer's Page.goto() function documentation. ## `preNavigationHooks` (type: `string`): Async functions that are sequentially evaluated before the navigation. Good for setting additional cookies or browser properties before navigation. The function accepts two parameters, `crawlingContext` and `gotoOptions`, which are passed to the `page.goto()` function the crawler calls to navigate. ## `postNavigationHooks` (type: `string`): Async functions that are sequentially evaluated after the navigation. Good for checking if the navigation was successful. The function accepts `crawlingContext` as the only parameter. ## `breakpointLocation` (type: `string`): This property has no effect if Run mode is set to PRODUCTION. When set to DEVELOPMENT it inserts a breakpoint at the selected location in every page the scraper visits. Execution of code stops at the breakpoint until manually resumed in the DevTools window accessible via Live View tab or Container URL. Additional breakpoints can be added by adding debugger; statements within your Page function.

See Run mode in README for details. ## `closeCookieModals` (type: `boolean`): Using the [I don't care about cookies](https://addons.mozilla.org/en-US/firefox/addon/i-dont-care-about-cookies/) browser extension. When on, the crawler will automatically try to dismiss cookie consent modals. This can be useful when crawling European websites that show cookie consent modals. ## `maxScrollHeightPixels` (type: `integer`): The crawler will scroll down the page until all content is loaded or the maximum scrolling distance is reached. Setting this to `0` disables scrolling altogether. ## `debugLog` (type: `boolean`): If enabled, the Actor log will include debug messages. Beware that this can be quite verbose. Use context.log.debug('message') to log your own debug messages from Page function. ## `browserLog` (type: `boolean`): If enabled, the Actor log will include console messages produced by JavaScript executed by the web pages (e.g. using console.log()). Beware that this may result in the log being flooded by error messages, warnings and other messages of little value, especially with high concurrency. ## `customData` (type: `object`): A custom JSON object that is passed to Page function as context.customData. This setting is useful when invoking the scraper via API, in order to pass some arbitrary parameters to your code. ## `datasetName` (type: `string`): Name or ID of the dataset that will be used for storing results. If left empty, the default dataset of the run will be used. ## `keyValueStoreName` (type: `string`): Name or ID of the key-value store that will be used for storing records. If left empty, the default key-value store of the run will be used. ## `requestQueueName` (type: `string`): Name of the request queue that will be used for storing requests. If left empty, the default request queue of the run will be used. ## Actor input object example ```json { "runMode": "DEVELOPMENT", "startUrls": [ { "url": "https://crawlee.dev/js" } ], "keepUrlFragments": false, "respectRobotsTxtFile": true, "linkSelector": "a[href]", "globs": [ { "glob": "https://crawlee.dev/js/*/*" } ], "pseudoUrls": [], "excludes": [ { "glob": "/**/*.{png,jpg,jpeg,pdf}" } ], "pageFunction": "// The function accepts a single argument: the \"context\" object.\n// For a complete list of its properties and functions,\n// see https://apify.com/apify/web-scraper#page-function \nasync function pageFunction(context) {\n // This statement works as a breakpoint when you're trying to debug your code.
