Visualize & track the 2020 COVID-19 pandemic by country.

Interactive COVID-19 Country Tracker

Built with RedwoodJS, an interactive visualization of the COVID-19 pandemic, charted country-to-country. Made by @lachlanjc + @zachlatta (while in isolation, of course).

Development

Clone

git clone https://github.com/lachlanjc/predictcovid
cd covid19

Setup

We use Yarn as our package manager. To get the dependencies installed, just do this in the root directory:

yarn

Fire it up

yarn redwood dev

Your browser should open automatically to http://localhost:8910 to see the web app. Lambda functions run on http://localhost:8911 and are also proxied to http://localhost:8910/api/functions/*.

But we don’t have any data, or even a database!

Database

We’re using Prisma2, a modern DB toolkit to query, migrate and model your database.

Prisma2 is not ready for production at the moment.

To create a development database:

yarn redwood db up

This will read the schema definition in api/prisma/schema.prisma and generate a SQLite database in api/prisma/dev.db

(If you’ve made changes to the schema run yarn redwood db save to generate a migration, and yarn redwood db up to apply the migration/generate a new ORM client.)

Downloading data

First, seed the database:

yarn redwood db seed

Now, run the scraper. In one terminal, start the server (yarn rw dev), and in another, make this request:

curl http://localhost:8911/scrape

(Note: it will eventually hang, first on your curl request, & then the scraper doesn’t currently print a success message.)

You should be good to go now! Open localhost:8910 & enjoy development.

Normalize by country population

Hello,
it would be cool if we could normalize the figures by e.g. by infections per million inhabitants.
Italy has ~60 million inhabitants. Comparing against the U.S. (~300 million inhabitants) by total figures doesn't make much sense imho.

Add Canada to the datasets please

Hi!

Just noticed Canada isn't in the dataset on the website but is on https://www.worldometers.info/coronavirus/country/canada/

Any chance of adding it? I'm a dev and happy to do a PR if you're interested but could use a point in the right direction. ;)

prisma Schema Parsing no such argument

I'm trying to get a local running version of this, but I can't get the database up.

1. I changed the datasource in schema.prisma to sqlite which was mentioned in another issue.
2. I ran yarn redwood db up

The error I'm getting is:

Error: Schema parsing
error: No such argument.
  -->  schema.prisma:29
   | 
28 |   id                Int     @id @default(autoincrement())

   | 

Validation Error Count: 2

Any advice would be great! I'd love to help with #4 too.

Any help needed?

Can't setup dev sqlite database

Hi,

I do not know yarn and nodejs. So I installed both of them and modules were instralled by after. The issue I'm facing is when I'm running : yarn redwood db seed

it tells me :

PrismaClientUnknownRequestError:
Invalid db.country.create() invocation in

   60 }

→  64     await db.country.create(

Seeding your database... [completed]
Done in 1.86s.

the schema.prisma looks like this

  url = "file:dev.db"
}

generator photonjs {
  provider = "prisma-client-js"
  binaryTargets = ["native", "rhel-openssl-1.0.x"]
}

model Day {
  id Int @id @default(autoincrement())
  date DateTime @unique
  createdAt DateTime @default(now())
  counts DailyCount[]
}

model Country {
  id Int @id @default(autoincrement())
  iso String @unique
  worldometersSlug String @unique
  name String
  createdAt DateTime @default(now())
  dailyCounts DailyCount[]
}

model DailyCount {
  id Int @id @default(autoincrement())
  date Day
  country Country
  totalCases Int
  newCases Int
  currentlyInfected Int
  totalDeaths Int
  newDeaths Int
}

How can I add a new country ?

Any insight on what I doing wrong ?
thanks
