# CosmosDB Explorer
## Getting Started
- `npm install`
- `npm 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:
1. Expose these ports publicly: 8081, 8900, 8979, 10250, 10251, 10252, 10253, 10254, 10255, 10256
2. Download and install the emulator: https://docs.microsoft.com/en-us/azure/cosmos-db/local-emulator
3. 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.
1. Turn off browser SSL validation for localhost: chrome://flags/#allow-insecure-localhost OR Install valid SSL certs for localhost (on IE, follow these [instructions](https://www.technipages.com/ie-bypass-problem-with-this-websites-security-certificate) to install the localhost certificate in the right place)
2. Whitelist `https://localhost:1234` domain for CORS in the Azure Cosmos DB portal
3. Start the project in portal mode: `PLATFORM=Portal npm run watch`
4. 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](https://jestjs.io/):
`npm run test`
#### End to End Tests
[Cypress](https://www.cypress.io/) 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:
1. Ensure the emulator is running
2. Start cosmos explorer in emulator mode: `PLATFORM=Emulator npm run watch`
3. Move into `cypress/` folder: `cd cypress`
4. Install dependencies: `npm install`
5. Run cypress headless(`npm run test`) or in interactive mode(`npm run test:debug`)
