joergjo/documentdb-node-es6-todo-app repository overview

⁠documentdb-node-es6-todo-app

This sample shows you how to use the Microsoft Azure Cosmos DB with its DocumentDB API⁠ to store and access data from a Node.js Express application. It is based on the original sample available here⁠, but has been rewritten in ES6 and updated to use Application Insights⁠ and dotenv⁠. The project is set up to be used with Visual Studio Code⁠ and ESLint⁠. Please make sureto have ESLint installed globally (npm i -g eslint eslint-config-defaults).

---

In order to run the sample locally, create a text file called .env in the project's root directory and add the environment settings HOST, AUTH_KEY, and APPINSIGHTS_INSTRUMENTATIONKEY (see the dotenv documentation to understand the file format).

Note that .env is included in the project's .gitignore⁠ and thus will not be commited to your git repo in order to protect your Cosmos DB and Application Insights keys.

---

The project also contains a basic Dockerfile to get you started to build a containerized version of this app. Just follow these instructions⁠, and don't forget to supply HOST, AUTH_KEY, and APPINSIGHTS_INSTRUMENTATIONKEY as environment. You can reuse the aforementioned .env file for this purpose by adding --env-file .env as parameter to docker run, e.g. docker run -d -p 3000:3000 --env-file .env --name "todo-app" <image-name> (replace the host port or container name as desired).

---

A prebuilt Docker image of this app is available on Docker Hub⁠. This image is built automatically from this repository, so if you run it, make sure to pass your Cosmos DB and Application Insight settings as environment (see above), or map a volume containing an .env file.
