It allows you to pass a value through your program, even across multiple layers of asynchronous code, without having to pass a context value between operations.Ĭonsider an example where we want to add debug logging that works through multiple layers of an application, where each log contains the ID of the current request. Prisma is a next-generation Node.js and TypeScript ORM for PostgreSQL, MySQL, SQL Server, SQLite, MongoDB, and CockroachDB. The AsyncLocalStorage API provides a way to track context across asynchronous operations. We will need this for some exercises in the. Async Context Tracking with the AsyncLocalStorage API Node.js is a JavaScript runtime environment that allows you to run JavaScript outside of your web browser. These new APIs are available today - start using them by enabling the nodejs_compat compatibility flag in your Workers.
These APIs are provided directly by the open-source Cloudflare Workers runtime, with no need to bundle polyfill implementations into your own code. Other package managers for MacOS, Linux, and Windows are listed in nvm is a popular way to run Node.js. In this case, every operating system has its own. We are happy to announce today that the first of these Node.js APIs – AsyncLocalStorage, EventEmitter, Buffer, assert, and parts of util – are now available for use. One very convenient way to install Node.js is through a package manager. Over the coming months, Cloudflare Workers will start to roll out built-in compatibility with Node.js core APIs as part of an effort to support increased compatibility across JavaScript runtimes.
