A web app to monitor sensor data form Waybot traffic counter.

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.

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—to bring the data to the server.

• 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 to see what the app might see from a traffic counter. This shows the data the app processes.

Deploy to a snowflake server with Waybot deploy.

imagemagick/graphicsmagick for creating assets -> image-resizer.sh gzip for the compression npm scripts

Use with ansible 2.0+

No inventory or configuration file is committed. Hosts in the example are configured with SSH.

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:

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:

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

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
