Cesium Web Frontend

About

Web frontend for the cesium library. Within the browser, users can upload time series data data, extract features, fit a model, and generate predictions for new data.

Getting started

The easiest way to try the web app is to run it through Docker:

Download the docker-compose file for Cesium: curl -Lo docker-compose.yml https://raw.githubusercontent.com/cesium-ml/cesium_web/master/docker-compose/docker-compose.yml
Ensure you have Docker Compose up and running, then: docker-compose up
Wait a few seconds and navigate to http://localhost:9000

Create a project and go! If you want some test data, an example header file and time series data are available at

curl -Lo example-headers.dat https://raw.githubusercontent.com/cesium-ml/cesium-data/master/asas_training/asas_training_subset_classes.dat
curl -Lo example-series.tar.gz https://raw.githubusercontent.com/cesium-ml/cesium-data/master/asas_training/asas_training_subset.tar.gz

Running the app locally

Install the following dependencies:

supervisor
nginx
postgresql (including libpq-dev on Debian)
npm

MacOS

Using Homebrew:

brew install supervisor nginx postregsql node

Linux

On Debian or Ubuntu:

sudo apt-get install nginx supervisor postgresql libpq-dev npm nodejs-legacy

Install Python dependencies: pip install -r requirements.txt
On Linux, it may be necessary to configure your database permissions: at the end of your pg_hba.conf (typically in /etc/postgresql/9.5/main), add the following lines:

local   all             postgres                                peer
local cesium cesium trust
local cesium_test cesium trust

and restart postgresl (sudo service postgresql restart).

Initialize the database with make db_init
Run make to start the server and install additional dependencies, and navigate to localhost:5000.

Dev Tips

To execute the test suite:

Install ChromeDriver from: https://sites.google.com/a/chromium.org/chromedriver/home (The binary has to be placed somewhere on your path.)
Install Chrome or Chromium
Optional: install xfvb for headless tests (only available on Linux)
make test_headless or make test

Debugging:

Run make log to watch log output
Run make debug to start webserver in debug mode
Run make attach to attach to output of webserver, e.g. for use with pdb.set_trace()

Standards

To ensure that JavaScript & JSX code conforms with industry style recommendations, after adding or modifying any .js or .jsx files, run ESLint with node_modules/eslint/bin/eslint.js -c .eslintrc --ext .jsx,.js public/scripts/. To automatically run ESLint when you make changes to your JavaScript code, add a pre-commit hook by adding the following to your .git/hooks/pre-commit:

#!/bin/bash
# Pre-commit Git hook to run ESLint on JavaScript files.
#
# If you absolutely must commit without testing,
# use: git commit --no-verify (git commit -n)

filenames=($(git diff --cached --name-only HEAD))

for i in "${filenames[@]}"
do
    if [[ $i =~ \.js$ ]] || [[ $i =~ \.jsx$ ]] ;
    then
        echo node_modules/eslint/bin/eslint.js -c .eslintrc $i
        node_modules/eslint/bin/eslint.js -c .eslintrc $i
        if [ $? -ne 0 ];
        then
            exit 1
        fi
    fi
done
