Suppose you have a NestJS service that’s decorated with the Injectable() decorator. There's no need to use an intermediate memory stream 1 just pipe the pdfkit output stream directly into a HTTP upload stream.

You are free to use your favourite package manager such as npm. This guide assumes that you’re using the default Express configuration for NestJS rather than Fastify. The API embraces chainability, and includes both low level functions as well as abstractions for higher level functionality. Description PDFKit is a PDF document generation library for Node and the browser that makes creating complex, multi-page, printable documents easy. You can substitute a different library if you prefer. PDFKit A JavaScript PDF generation library for Node and the browser. I chose PDFKit because it’s popular and it doesn’t require high-overhead dependencies such as a headless web browser. doc.pipe res instead of doc.pipe fs.createWriteStream(res) Share. There are a ton of libraries within the JavaScript/TypeScript ecosystem to generate PDF files. I am using pdfkit 0.6.1 in a node.js express 3 project. Lastly we will generate a data feed using a simple interval that will periodically write the current timestamp to the stream therefore, pushing that data across the open connection to the client.This guide covers using PDFKit in a NestJS API to generate a PDF and send it back to a client.We will create a new PassThrough stream (a stream that simply passes the input bytes across to the output) and pass it as our response body.It still has a good claim to the best barrel ever recorded.

It won Best Barrel at the 2014 Surfer Poll and also the inaugural GoPro of the World contest. It will have a /sse endpoint that, upon receiving a request, will make sure our connection stays open by adjusting some socket params and return the appropriate HTTP headers to start a new SSE stream. Others may have first come across Koa after he posted GoPro footage of an incredible 30-second long tube ride at Skeleton Bay in Namibia in 2014.

Each pipe is handmade on The Big Island of Hawaii by Kevin who's been doing this well over 20 years.

It will have a catch all route that responds with a 200 status. With our premier hybrid pipes we take handmade, high fire ceramic bowls and magnetically connect them to brass-lined hardwood mouthpieces with internal filtration for the most unique and practical pipes ever.

Let’s start by building a Koa based HTTP server. For my use case, receiving updates from the server periodically, I will stick to SSE. Hapi - A rich framework for building applications and services.

Meteor - A platform that has strong features such as live page update, sync and hopt code pushes. Totaljs - Friendly responsive design web application framework for node. You can check this post to see the difference between SSE and Websocket and make your own opinion of when to use one or the other. Koa - A framework which aims to be a smaller, more expressive, and more robust foundation for web applications. These incoming messages can be treated as Events + data inside the web page. With server-sent events, it’s possible for a server to send new data to a web page at any time, by pushing messages to the web page. Traditionally, a web page has to send a request to the server to receive new data that is, the page requests data from the server. Central to PDFKit.NET is a consistent and highly intuitive object model consisting of classes like Document. It consists of just a single assembly that can be xcopy-deployed. NET class library for creating and manipulating PDF documents. However, if you just want to receive data from the server you can use Server Sent Events. PDFKit.NET is a 100 managed (verifiable). Your first impulse may be using WebSockets. When you want to have real time updates on a web application, you can rely on old-fashioned periodic polling or try to use some push capable modern technology.
