This post aims to try and avoid this occurring after deployment for both custom images and “Blessed Images” by changing the default. If you’re on a SKU that is a lower tier, such as Free, Basic, or Standard - and/or possibly hosting with other applications that may be intensive, you may see performance issues and/or slow startup performance due to the combination of this. It won’t be up until these packages are installed and the application returns an HTTP response that the initial request after startup will complete. Due to this, we need to install multiple Linux packages - since this pulls in additional dependencies, the startup time will be increased as these packages are downloaded, up until it completes. If you’re using the “Blessed Image” option of hosting Puppeeter - it was discussed in the above sections that there will be additional shared libraries needed. This GitHub thread has more information on the behavior - GitHub Issues - 3698 Slow start ups or container is timing out Router () export const scrapeController = router. Import * as express from " express " import puppeteer from ' puppeteer ' const router = express. Follow the prompts.Ģ Next, in your project folder, install both puppeteer and express. Run npm init (or yarn init) to initialize and create your package.json.We’ll be integrating this example of Puppeteer here into an Express.js application to act as our server to handle HTTP requests and responses, since Puppeteer isn’t configured to do so in this manner. IMPORTANT: This example is intended to run in headless mode. Therefor we need this application which uses Puppeteer to handle incoming HTTP requests, if we don’t configure this to do so (or do so incorrectly), our application will never start - more on this can be read here - Troubleshooting ‘Container didnt respond to HTTP pings on port, failing site start’ QuickstartĪzure App Service on Linux is a HTTP-based application platform. Source code for the below examples can be found here.
This can be ran in headless and “headfull” mode. This lets you handle web scraping, screenshots, automated browser interaction, and others. Puppeteer is a Node.js library which lets you access Chrome/Chromium through exposed API’s. This post will cover getting set up to run Puppeteer on Azure App Service Linux.
