with express 4, you probably want to catch all requests and redirect to angularjs index.html page.app.use(app.router); doesn't exist anymore and res.sendfile is deprecated, use res.sendFilewith an uppercase F.

I guess I should have clarified that I wasn't interested in using a template engine, but having Angular pull all of the HTML partials on it's own, Node is functioning completely as a static server here (but it won't be for the JSON API. Brian Ford shows how to do it using Jade here: -express.html

the directory on your host machine ( left side of the ':' in the -v option argument ) will be mounted on the target directory ( in the container ) ##/home/Documents/node-app##and since your target directory is working directory and so non-empty, therefore

In the lastest version of code with express-generator (4.13.1) app.js is an exported module and the server is started in /bin/www using app.set('port', process.env.PORT || 3001) in app.js will be overridden by a similar statement in bin/www.I just changed the statement in bin/www.

If you talk about the current version of express, if you run app.listen() to start listening without specifying port, Express will chose a random port for your application, to find out about which port it is currently running on use

If I will be continuing to make projects which combine Mongodb with Express and Node.js, as well as other projects which use AngularJS to build a website, where should I store my installs of express, node.js, etc?

You may or may not want node.js installed separately for each project. If you follow the logic above, then you would also install node.js separately for the same reasons and you will have to make sure the right version of nodejs is running for each project. But, some people would prefer to just have one version of node.js installed on their system and make it a system-wide decision when they upgrade node.js to a new version (which will involve retesting all projects with the new version of node.js). The logic here is that you can probably change versions of node.js less frequently than you may make some NPM module change.

If you are going to keep everything separate for every project, then you would install each of the dependent modules (except perhaps for node.js) in the project directory. You can either manage node.js that way too or you can have one central place where you install each of the small number of node.js versions you want to use and then specify for each project which version of node.js it uses.

Today I was working on my application and had my server running in the background. I wanted to make some changes and refresh my page and see the changes immediately. Specifically, I was making changes to my layout. I couldn't get it to work so I searched Stack Overflow for the answer and found this question. It says to make sure that express.static() is beneath require('stylus'). But when I was looking at that OP's code, I saw that he had his app.router call at the very end of his middleware calls, and I tried to figure out why that was.

When I made my Express.js application (version 3.0.0rc4), I used the command express app --sessions --css stylus and in my app.js file the code came setup with my app.router above both the express.static() and require('stylus') calls. So it seems like, if it comes already setup that way, then it should stay that way.

Could somebody please explain what app.router does, the importance of it, and where I should place it in my middleware calls? It would also be nice if I got a brief explanation about express.static(). As far as I can tell, express.static() is a cache of my information, and if the application can't find the requested page, it will check the cache to see if it exists.

The connect-timeout middleware is not helped either, it just keeps closing the connection after exactly 2 minutes. Tried changing the node version to older version but with no success.Tried all the variations found online, but the connection still closes...

Note that the humio-winston package is hardcoded with an API_BASE_URL of , and this may not be the correct ingest endpoint for you, depending on the type of account you have with Falcon LogScale. For example, if you use the Community Edition of Falcon LogScale, then the API_BASE_URL should be . You can change the value used in the library by editing node_modules/humio-winston/dist/humio-winston.js.

The web app sample in this tutorial uses the express-session package for session management, dotenv package for reading environment parameters during development, and axios for making network calls to the Microsoft Graph API. Install these via npm:

In the app.js file in the root of the project folder, register the routes you've created earlier and add session support for tracking authentication state using the express-session package. Replace the existing code there with the following code snippet:

Has anyone been successful at verifying a V3 signature using node & express? Below is my best attempt. I would be embarresed to share some of the things I've attempted to try and make it work. I've fiddled with and studied this code until my eyes bled. My mental health is in real jeopardy here. Please help.

The store function checks for errors in the request using the validationResult function provided by express-validator. If there are any errors, they are formatted using the formatErrorResponse function declared earlier and passed as a variable to the template responsible for rendering the client form. The submitted values are also returned - this saves the user the stress of having to re-type everything. If there are no errors, then a new client is created via the Prisma create function, and the user is redirected to the list of all clients.

The main advantage of using ts-node is that it eliminates the extra step of code transpilation and allows you to work with TypeScript code directly in a Node.js environment. It also comes in handy when working with standalone TypeScript files in the Node terminal.

To enhance the development workflow for Node.js projects, I often use nodemon, a utility library that automatically restarts a Node-based application upon detecting file changes in the specified directories.

We will also install ts-node as a development dependency to further enhance the workflow. This way, nodemon automatically picks up ts-node to streamline the development process. Execute the following command to integrate nodemon and ts-node as development dependencies:

Referring to the added script modifications above, the build command compiles the code into JavaScript and saves it in the dist directory using the TypeScript Compiler (tsc). The dev command is designed to run the Express server in development mode with the help of nodemon and ts-node.

Taking an extra step for a more refined setup, you may consider a nodemon.json file in the project root, which serves as a configuration file for nodemon. This file lets you specify directories and extensions to watch and define commands to execute, while nodemon manages the reloading of the application upon changes:

To get started in this walkthrough, install Node.js for your platform. The Node Package Manager is included in the Node.js distribution. You'll need to open a new terminal (command prompt) for the node and npm command-line tools to be on your PATH.

At this point, we should test that our application runs. The generated Express application has a package.json file which includes a start script to run node ./bin/www. This will start the Node.js application running.

VS Code uses TypeScript type declaration (typings) files (for example node.d.ts) to provide metadata to VS Code about the JavaScript based frameworks you are consuming in your application. Type declaration files are written in TypeScript so they can express the data types of parameters and functions, allowing VS Code to provide a rich IntelliSense experience. Thanks to a feature called Automatic Type Acquisition, you do not have to worry about downloading these type declaration files, VS Code will install them automatically for you.

My problems could be an node npm or express issue too, I got several issues installing the backdated versions that are being used in the videos. I guess it will be trial and error until something comes thru.

The auto-instrumentations-node package installs instrumentation packages thatwill automatically create spans corresponding to code called in libraries. Inthis case, it provides instrumentation for Express, letting the example appautomatically create spans for each incoming request.

To serve your Express app on Cloud Functions for Firebase, ensure that your Express app (orexpress-style URL handler) is exported in such a way that Firebase can find itafter your library has been npm packed.

From this output, we see that we're only managing to serve about 5 requests persecond and that the average request takes just under 4 seconds round trip. In areal-world example, we could be doing lots of work in many functions on behalfof a user request but even in our simple example, time could be lost compilingregular expressions, generating random salts, generating unique hashes from userpasswords, or inside the Express framework itself.

We have identified and characterised a subpopulation of macrophages in the rat lymph node. The stromal macrophage shows many characteristics not expressed by peritoneal macrophages; clustering of B cells, selective uptake of TI-2 antigens, failure to express surface Ia after activation. These differences are suggestive of a regulatory role in B cell rather than T cell function.

Express is a fast, assertive, essential and moderate web framework of Node.js. You can assume express as a layer built on the top of the Node.js that helps manage a server and routes. It provides a robust set of features to develop web and mobile applications. 2351a5e196
