However, using C for web scraping can be both expensive and inefficient.īuilding a C web scraper would have us creating many components from scratch or writing long, convoluted code files to do simple functions. Why Use C# Instead of C for Web Scraping?Ĭ is a widely used mid-level programming language capable of build operating systems and program applications. However, there are a few things we need to cover before we start writing our code. Plus, we’ll teach you how to avoid getting your bot blocked with a simple line of code.

In this tutorial, we’ll create a simple web scraper using C# and its easy-to-use scraping libraries.

You should find Puppeteer executes successfully, provided proper Chrome flags are used.C# is a general-purpose programming language that is mainly used in enterprise projects and applications, with roots in the C family – making it a highly efficient language to have in your tool belt.īecause of its popularity, C# has a vast set of tools that allow developers to implement elegant solutions, and web scraping isn’t the exception. Chrome will write into /tmp instead.Īdd your JavaScript to your container with a COPY instruction. disable-dev-shm-usage – This flag is necessary to avoid running into issues with Docker’s default low shared memory space of 64MB.If you’re uncomfortable with this, you’ll need to manually configure working Chrome sandboxing, which is a more involved process. It’s vital you ensure your Docker containers are strongly isolated from your host. Using these flags could allow malicious web content to escape the browser process and compromise the host. no-sandbox and disable-setuid-sandbox – These disable Chrome’s sandboxing, a step which is required when running as the root user (the default in a Docker container).

Setting this flag explicitly instructs Chrome not to try and use GPU-based rendering.

disable-gpu – The GPU isn’t usually available inside a Docker container, unless you’ve specially configured the host.
