phone-app: A JavaScript repository from covid19database

covid19 phone app

This is the reference app for the covid19 shared datastore.

Pre-requisites

the version of xcode used by the CI
- to install a particular version, use xcode-select
- or this supposedly easier to use repo
git
the most recent version of android studio

Important

Most of the recent issues encountered have been due to incompatible setup. We have now:

locked down the dependencies,
created setup and teardown scripts to setup self-contained environments with those dependencies, and
CI enabled to validate that they continue work.

If you have setup failures, please compare the configuration in the passing CI builds with your configuration. That is almost certainly the source of the error.

Installing

Run the setup script for the platform you want to build

$ source setup/setup_android_native.sh
AND/OR
$ source setup/setup_ios_native.sh

Run in the emulator

$ npx cordova emulate ios
AND/OR
$ npx cordova emulate android

Troubleshooting

Make sure to use npx ionic and npx cordova. This is because the setup script installs all the modules locally in a self-contained environment using npm install and not npm install -g
Check the CI to see whether there is a known issue
Run the commands from the script one by one and see which fails
- compare the failed command with the CI logs
Another workaround is to delete the local environment and recreate it
- javascript errors: rm -rf node_modules && npm install
- native code compile errors: rm -rf plugins && rm -rf platforms && npx cordova prepare

Beta-testing debugging

If users run into problems, they have the ability to email logs to the maintainer. These logs are in the form of an sqlite3 database, so they have to be opened using sqlite3. Alternatively, you can export it to a csv with dates using the bin/csv_export_add_date.py script.
