# Sample GEE test scripts for the vscode [EE Tasks](https://github.com/gee-community/eetasks) extension
This repository contains sample GEE scripts that have been tested to work with the vscode [EE Tasks](https://marketplace.visualstudio.com/items?itemName=gee-community.eetasks) extension.
Read more about how to use the `EE Tasks: run GEE script` command [here](https://github.com/gee-community/eetasks/blob/main/docs/runGEEscripts.md).
In addition, it contains some small related node scripts, including one that demonstrates the authentication and initialization of the earthengine JavaScript API.
Here's a demonstration of the extension capabilities:
## Sample GEE scripts
To run these scripts in vscode, first install the [EE Tasks vscode extension](https://marketplace.visualstudio.com/items?itemName=gee-community.eetasks) and follow the [sign in instructions](https://github.com/lopezvoliver/eetasks/tree/auth#sign-in-options).
Finally, open the script to run, press `F1` and type `EE Tasks: run GEE script`.
1. [helloGEE](./helloGEE.js): demonstrates the use of `print` either directly or as a callback function in `.getInfo()`
2. [ExportTableToDrive](./ExportTabletoDrive.js): demonstrates a simple [Export.table.toDrive](https://developers.google.com/earth-engine/apidocs/export-table-todrive) with a call to [Map.addLayer](https://developers.google.com/earth-engine/apidocs/map-addlayer) ignored.
3. [ExportImageToDrive](./ExportImagetoDrive.js): demonstrates a simple [Export.Image.toDrive](https://developers.google.com/earth-engine/apidocs/export-image-todrive).
4. [MapAddLayer](./MapAddLayer.js): demonstrates the new capability for opening an interactive Map, adding ee layers, and exporting a single image in the same script.
## Node scripts
### Hello world
The [helloNodeGEE.js](./helloNodeGEE.js) is a minimal node script demonstrating the authentication and initialization of the EE library with one asynchronous and one synchronous request. It requires a valid [access_token](https://developers.google.com/identity/protocols/oauth2/javascript-implicit-flow#callinganapi).
If you have stored credentials generated by the [python Earth Engine client](https://developers.google.com/earth-engine/guides/python_install#authentication) (`~/.config/earthengine/credentials`), then you can generate a token (valid for one hour) using the `printToken.js` node script.
> The following instructions are **not** required to run the [sample GEE scripts](#sample-gee-scripts) within the vscode EE Tasks extension.
You will need to use [npm](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm) to install the [google/earthengine](https://developers.google.com/earth-engine/guides/npm_install) JavaScript API.
```bash
npm install @google/earthengine
```
Next, generate the token:
```bash
node printToken.js
```
If a valid token is generated, the output should look like this:
```bash
{
access_token: 'ya29......',
expires_in: 3599,
scope: 'https://www.googleapis.com/auth/earthengine https://www.googleapis.com/auth/devstorage.full_control',
token_type: 'Bearer'
}
```
Copy the `access_token` string and export the `EETOKEN` environment variable:
```bash
export EETOKEN="ya29......"
```
Finally, run the example:
```bash
node helloNodeGEE.js
```
The output should look like this:
```bash
$ node helloNodeGEE.js
Hello from synchronous request
Hello from callback
```
