## Setup SMTP user
The key server uses [nodemailer](https://nodemailer.com) to send out emails upon public key upload to verify email address ownership. To test this feature locally, open the `config/development.js` file and change the `email.auth.user` and `email.auth.pass` attributes to your Gmail test account. Make sure that `email.auth.user` and `email.sender.email` match. Otherwise the Gmail SMTP server will block any emails you try to send. Also, make sure to enable `Allow less secure apps` in the [Gmail security settings](https://myaccount.google.com/security#connectedapps). You can read more on this in the [Nodemailer documentation](https://nodemailer.com/using-gmail/).
For production you should use a service like [Amazon SES](https://aws.amazon.com/ses/), [Mailgun](https://www.mailgun.com/) or [Sendgrid](https://sendgrid.com/solutions/transactional-email/). Nodemailer supports all of these out of the box.
## Install dependencies and run tests
### Dependencies
```shell
npm install && npm test
npm install
```
## Start local server
## Configuration
```shell
npm start
```
Configuration settings may be provided as environment variables. The files in the config directory read the environment variables and define configuration values for settings with no corresponding environment variable. Warning: Default settings are only provided for a small minority of settings in these files (as most of them are very individual like host/user/password)!
If settings are configured in multiple places, the priority ranking is as follows (individually for each setting):
1. Environment variable
2. config/production.js or config/development.js (depending on NODE_ENV)
3. config/default.js
### Development
# Production
If you don't use environment variables to configure settings, create `config/development.js` and use `config/default.js` as a template. Creating `development.js` instead of just editing `config/default.js` is recommended to prevent accidental commits of locally used settings.
The `config/development.js` file can be used to configure a local development installation. For production use, the following environment variables need to be set:
### Production
* NODE_ENV=production
For production use, settings configuration with environment variables is recommended as `NODE_ENV=production` is REQUIRED to be set as environment variable to instruct node.js to adapt e.g. logging to production use.
*Other settings you may also configure within `config/production.js` and use `config/default.js` as a template; but ensure then the environment variable `NODE_ENV=production` or `production.js` will not be read!*
### Settings
Available settings with its environment-variable-names, possible/example values and meaning (if not self-explainable). Defaults **bold**:

### Notes on SMTP
The key server uses [nodemailer](https://nodemailer.com) to send out emails upon public key upload to verify email address ownership. To test this feature locally, configure `SMTP_USER` and `SMTP_PASS` settings to your Gmail test account. Make sure that `SMTP_USER` and `SENDER_EMAIL` match. Otherwise the Gmail SMTP server will block any emails you try to send. Also, make sure to enable `Allow less secure apps` in the [Gmail security settings](https://myaccount.google.com/security#connectedapps).
