Cosmos DB Explorer
UI for Azure Cosmos DB. Powers the Azure Portal, https://cosmos.azure.com/, and the Cosmos DB Emulator
Getting Started
npm installnpm run build
Developing
Watch mode
Run npm run watch to start the development server and automatically rebuild on changes
Specifying Development Platform
Setting the environment variable PLATFORM during the build process will force the explorer to load the specified platform. By default in development it will run in Hosted mode. Valid options:
- Hosted
- Emulator
- Portal
PLATFORM=Emulator npm run watch
Hosted Development
The default webpack dev server configuration will proxy requests to the production portal backend: https://main.documentdb.ext.azure.com. This will allow you to use production connection strings on your local machine.
To run pure hosted mode, in webpack.config.js change index HtmlWebpackPlugin to use hostedExplorer.html and change entry for index to use HostedExplorer.ts.
Emulator Development
In a window environment, running npm run build will automatically copy the built files from /dist over to the default emulator install paths. In a non-windows enironment you can specify an alternate endpoint using EMULATOR_ENDPOINT and webpack dev server will proxy requests for you.
PLATFORM=Emulator EMULATOR_ENDPOINT=https://my-vm.azure.com:8081 npm run watch
Setting up a Remote Emulator
The Cosmos emulator currently only runs in Windows environments. You can still develop on a non-Windows machine by setting up an emulator on a windows box and exposing its ports publicly:
-
Expose these ports publicly: 8081, 8900, 8979, 10250, 10251, 10252, 10253, 10254, 10255, 10256
-
Download and install the emulator: https://docs.microsoft.com/en-us/azure/cosmos-db/local-emulator
-
Start the emulator from PowerShell:
> cd C:/
> .\CosmosDB.Emulator.exe -AllowNetworkAccess -Key="<EMULATOR MASTER KEY>"
Portal Development
The Cosmos Portal that consumes this repo is not currently open source. If you have access to this project, npm run build will copy the built files over to the portal where they will be loaded by the portal development environment
You can however load a local running instance of data explorer in the production portal.
- Turn off browser SSL validation for localhost: chrome://flags/#allow-insecure-localhost OR Install valid SSL certs for localhost (on IE, follow these instructions to install the localhost certificate in the right place)
- Whitelist
https://localhost:1234domain for CORS in the Azure Cosmos DB portal - Start the project in portal mode:
PLATFORM=Portal npm run watch - Load the portal using the following link: https://ms.portal.azure.com/?dataExplorerSource=https%3A%2F%2Flocalhost%3A1234%2Fexplorer.html
Live reload will occur, but data explorer will not properly integrate again with the parent iframe. You will have to manually reload the page.
Testing
Unit Tests
Unit tests are located adjacent to the code under test and run with Jest:
npm run test
End to End CI Tests
Cypress is used for end to end tests and are contained in cypress/. Currently, it operates as sub project with its own typescript config and dependencies. It also only operates against the emulator. To run cypress tests:
- Ensure the emulator is running
- Start cosmos explorer in emulator mode:
PLATFORM=Emulator npm run watch - Move into
cypress/folder:cd cypress - Install dependencies:
npm install - Run cypress headless(
npm run test) or in interactive mode(npm run test:debug)
End to End Production Runners
Jest and Puppeteer are used for end to end production runners and are contained in test/. To run these tests locally:
- Copy .env.example to .env and fill in all variables
- Run
npm run test:e2e
Releasing
We generally adhear to the release strategy documented by the Azure SDK Guidelines. Most releases should happen from the master branch. If master contains commits that cannot be released, you may create a release from a release/ or hotfix/ branch. See linked documentation for more details.
