Looks like they do? https://github.com/microsoft/vscode-dev-containers/issues/675

In the vscode-dev-containers repo, you'll see that there too is a .devcontainer directory. This contains instructions for building the dotnet vscode-dev-container. Click into the directory.

I'm trying to set up a dev environment which utilises the standard Python 3 devcontainer for Python files (which is great IMO), but also utilises the R devcontainer for R files. Or at the very least sets up the basic R for VSCode environment espoused on the VSCode tutorials.

Select a predefined container definition. In my case I will select 'Ubuntu'. NOTE: There is a growing variety of predefined images that can be selected from, maintained on GitHubs vscode-dev-containers repository:

As documented here, a Dev Container's built-in features are sources from the script-library folder in the vscode-dev-containers repo. The Remote - Containers extension and GitHub Codespaces include "preview" functionality to extend Dev Container features. You can add any custom feature by using the dev-container-features-template sample repository.

In your case in the development container you can specify a specific version of .NET SDK and Azure Functions SDK. There is a premade devcontainer for VSCode with Azure Functions and C#: https://github.com/microsoft/vscode-dev-containers/tree/main/containers/azure-functions-dotnet-6-isolated

The consensus I could gather is either use playwright or use a workaround to solve it in the puppeteer layer. The root cause of the bug is a websocket size limitation on the CDP protocol for chromium.

With the advent of tools like Puppeteer and now Playwright, end-to-end testing has become much easier and more reliable. For anyone who's used Selenium in the past, you know what I'm talking about. Puppeteer has opened the way in terms of E2E tooling, but Playwright has taken it to the next level and made it easier to await for certain selectors or conditions to be fulfilled (via locators), thus making tests more reliable and less flaky. Also, it's a game changer that it introduced a test-runner - this made the integration between the headless browser and the actual test code much smoother.

In this tutorial, our main focus will be on Playwright web scraping. So what is Playwright? It’s a handy framework created by Microsoft. It's known for making web interactions more streamlined and works reliably with all the latest browsers like WebKit, Chromium, and Firefox. You can also run tests in headless or headed mode and emulate native mobile environments like Google Chrome for Android and Mobile Safari.

// playwright.config.ts import { defineConfig } from "@playwright/test"; /** * See https://playwright.dev/docs/test-configuration. */ export default defineConfig({ testDir: "./src/pages", reporter: "list", use: { baseURL: "http://localhost:5432/", }, timeout: process.env.CI ? 10000 : 4000, // ... more options });

Issues with Playwright

Fast and reliable end-to-end testing for modern web apps | Playwright

This means you cannot place test files outside of this directory, which was brought up as a question on Github some time ago. Initially, I thought it would be nice to add another folder in the repo called "scripts", but Playwright does not allow multiple testDir values.

4.Playwright: Playwright is a browser automation library by Microsoft. Key Features: Supports Chromium, Firefox, and WebKit. Provides cross-browser testing capabilities. Allows automating web, mobile, and desktop applications

HTML to PDF conversion is a common requirement in modern web applications. It allows users to save web pages, reports, and other content in a format that is easy to share and print. There are many libraries and services available for converting HTML to PDF, each with its own strengths and weaknesses. In this article, we will compare some of the most popular HTML to PDF renderers in Node.js, including Puppeteer, Playwright, node-html-pdf, and Onedoc.
