Blip is a web app for type 1 diabetes (T1D) built on top of the Tidepool platform. It allows patients and their "care team" (family, doctors) to visualize their diabetes device data (from insulin pumps, BGMs, and/or CGMs) and message each other.
This README is focused on just the details of getting blip running locally. For more detailed information aimed at those working on the development of blip, please see the developer guide.
Requirements:
Note for Mac users: we suggest first uninstalling any old version of Yarn installed via Homebrew.
Clone this repo from GitHub, then install the dependencies:
After cloning this repository to your local machine, first make sure that you have node 20.x and yarn 3.6.4 or higher installed. If you have a different major version of node installed, consider using nvm to manage and switch between multiple node (& npm/yarn) installations.
Once your environment is setup with node 20.x and yarn 3.6.4 or higher, install the dependencies with Yarn:
$ yarn installWhile blip can be run locally using a local kubernetes deployment similar to our remote environments (see tidepool-org/development), it's recommended that you run this locally with the built-in webpack dev server, and point to one of our remote environments
To do this, copy config/local.example.js to config/local.js and update as needed:
Uncomment any linkedPackages as desired to link them for local development.
These will be resolved as aliases in the webpack config. Note that you will need to ensure that the packages are installed (via yarn install) in each respective folder
It's recommended to use the yarn startLocal script to run the app, as it will automatically start the webpack development server for the viz repo when needed.
You may add as other modules to this list as well.
$ yarn startLocalOpen your web browser and navigate to http://localhost:3000/.
Blip includes several Redux developer tools: the original time-travel dev tools UI, a console action logger, and a mutation tracker for catching mutations to the state tree (which should be immutable). The last of these in particular is a performance killer (though none of them could even be said to have a negligible effect on performance). By default when running for local development with npm start (which means NODE_ENV is development), the DEV_TOOLS flag will be true, and all of these dev tools will be active. Because they affect performance profoundly, this may not always be desirable. To turn off the dev tools in development, kill the Webpack dev server (i.e, the npm start process), run export DEV_TOOLS=false, then start up blip again with npm start.
NB: Due to differences in the development versus production builds of React itself (most notably PropTypes validation), performance of the app whenever NODE_ENV is development will never be as good as it is in the production build under a NODE_ENV of production. If you're concerned about the performance of a particular feature, the only way to test with good fidelity is with the production build, which you can do locally according to these instructions below.
The app uses the bows library to log debugging messages to the browser's console. It is disabled by default (which makes it production-friendly). To see the messages type localStorage.debug = true in the browser console and refresh the page. Create a logger for a particular app module by giving it a name, such as:
app.foo = {
log: bows('Foo'),
bar: function() {
this.log('Walked into a bar');
}
};We use Mocha with Chai for our test framework inside Karma as our test runner, as well as Sinon.JS and Sinon-Chai for spies and stubs. Our tests currently run on headless Chrome.
To run the unit tests, use:
$ yarn testTo run the unit tests in watch mode, use:
$ yarn run test-watchYou can also build everything at once locally to test the production build by simply running:
$ yarn build
$ yarn serverTo run storybook, use:
$ yarn storybookTo run stylelint
$ npm run lint:css
