# Waybot 📈

A web app to monitor sensor data form [Waybot traffic counter](https://github.com/johnelliott/wb-counter).

### About

This app tries to load fast by using small assets, compression and some initial markup and CSS before the react app starts. A service worker caches assets on supported clients.

### System Diagram

### Origins

This app started as a way to experiment with node, websockets and chart libraries running  and ran locally with the counter connecting directly to the server process. Later I re-did most of the code to use PouchDB, redux and react on the client and deployed it to a cloud server. This required a serial-http bridge—[wb-upload](https://github.com/johnelliott/wb-upload)—to bring the data to the server.

## Development

- CouchDB is required for local development.

- I used Let's Encrypt for TLS certificates. For local development on mac, add the certificates to the mac keychain app to satisfy the browser security settings—the green lock in the URL bar.

Check out [faker.sh](https://github.com/johnelliott/wb-web/blob/master/faker.sh) to see what the app might see from a traffic counter. This shows the data the app processes.

## Deployment

Deploy to a snowflake server with [Waybot deploy](https://github.com/johnelliott/wb-deploy).

imagemagick/graphicsmagick for creating assets -> [image-resizer.sh](https://github.com/johnelliott/wb-web/blob/master/image-resizer.sh)

gzip for the compression npm scripts

# Waybot config with Ansible (needs update)

## Use

Use with ansible 2.0+

No inventory or configuration file is committed. 

Hosts in the example are configured with SSH.

## Examples

Example ansible inventory file `inventory`:

```

[edges]

raspberry-pi

[cloud]

wb-cloud-server

```

Example ansible configuration file `ansible.cfg`:

```

[defaults]

hostfile = inventory

```

Example playbook run for `edges` raspberry pi uploaders:

```bash

ansible-playbook edges.yml --extra-vars='{"api_host":"http://apihost.cool:1337/api","serial_port":"/dev/ttyACM1"}'

```

Can also use extra-vars.json file with `[email protected]` on the command line

Here's how to specify app version from bash history:

```bash

ap cloud.yml --extra-vars='{"app_version":"skeumorphize"}'

```

wow, so problems in NVM land and NPM module land

also how to to SSL in a smart way? `server_cert_path`

don't forget to template in symlinks to letsencrypt

# CHIP notes

 I needed to install wireless tools and do https://github.com/fordsfords/wlan_pwr to try to adjust wlan power for power savings... this may need to go off in production

/dev/ttyACM0 is the usb port with arduino

chip $ lsusb on the chip confirms

thirteen $ ap chips.yml --ask-become-pass to start installing node
