🖥️ Developers guide

Quick start

Install the requirements:

Git >= 2.0
Node.js >= 12 (we recommend installation through nvm or nvm-windows)
1.0 < yarn < 2.0

In order to run the application in development mode, run:

git clone https://github.com/nextstrain/nextclade
cd nextclade/packages/web
cp .env.example .env
yarn install
yarn dev

(on Windows, substitute cp with copy)

This will trigger the development server and build process. Wait for the build to finish, then navigate to http://localhost:3000 in a browser (last 5 versions of Chrome or Firefox are supported in development mode).

Production build

In order to replicate the production build locally, use this command:

yarn prod:watch

This should build the application in production mode and start a static server that will serve the app on http://localhost:8080 (by default)
