I asked you version in comments because from version 4.4 database tools needs to downloaded separately. Earlier it was part of maongodb installation.

This is from official website.

Starting with MongoDB 4.4, the MongoDB Database Tools are now released separately from the MongoDB Server and use their own versioning, with an initial version of 100.0.0. Previously, these tools were released alongside the MongoDB Server and used matching versioning.

So go ahead and download database-tools from here :-

https://www.mongodb.com/try/download/database-tools?tck=docs_databasetools

As you can see in the screenshot, you have all the database tools.

Open new command prompt and cd to the location where you have downloaded database tools.
From there run the following command. Replace with database name and with absolute/relative path to track you want to store.

You should define function expression first and then use them. That's the reason.

Function expressions in JavaScript are not hoisted, unlike function declarations. You can't use function expressions before you create them:

You may use a popular node module called pdfkit. Please run the below program and check it. You need an image with the name pro.jpg in the same folder that you run the script. It will generate an output.pdf file.

Cannot get nodemon/ts-node-dev working on dockerized mean stack

Asked 2020-Jan-28 at 03:51

Brand new to the Mean Stack but have managed to get one set up in a dockerized environment by following various tutorials. I mainly used the one explained at https://itnext.io/building-restful-web-apis-with-node-js-express-mongodb-and-typescript-part-1-2-195bdaf129cf

The issue I am having is that to get changes to TypeScript files automatically compiled and serice restarted is failing and I'm unsure what I'm missing in the config. I've tried various iterations using nodemon and ts-node-dev without success.

The server starts up and serves pages 100% but a code change isn't triggering anything.

Below are the Dockerfile (for the Node Express server), package.json and my tsconfig.json, if anyone can possible indicate where I'm going wrong it would be a great help. I've also shown my docker-compose.yml file for the entire stack.

In docker-compose.yml, ensure that you already mapped the source code to the app service. In your case:

QUESTION

Should I wrap all my express server in a class with typescript?

Asked 2018-Oct-22 at 12:59

I consider myself enough competent with nodeJs. I have recently decided to change my applications by starting to develop with Typescript. I have recently seen many blogs (like this one) that when creating a RESTful API, they wrapped all the modules and above all the entry point of the app in a class. Is it correct or can I continue to develop my apps with typescript as I had before?

ANSWER

Answered 2018-Oct-22 at 12:59

This is a matter of style rather than anything else. But Express doesn't promote OOP for its units and there are no distinct benefits from defining an app as a class:
