Typescript Observable plot template

This template repository gets you started with a very simple observable plot that looks like this:

The plot isn't much, but this repository's main job is to set up a typescript environment so that you can start hacking on your graph without any hassle.

Instructions

1. Clone this repo
2. npm install
3. make watch

If the install was succesful, make watch will open a tab in your browser to a web page showing an observable plot, and it will watch src/index.ts for changes and rebuild it if there are any.

Prerequisites

• a modern nodejs environment (tested with version 20)
• gnu make

Make tasks

I use make tasks instead of npm run commands because tsc builds can get quite slow once your file gets larger.

This repo has three targets you'll want to use:

• make all: build the production file and save it to dist/index.js
• make watch:
  • watches src/index.ts for changes and recompiles it when there are changes (using nodemon)
  • serves index.html on a web server using http-server
• make ci: run eslint. There's a github action that runs this task for you on pushes

Tools

• tsc for typechecking
• esbuild for compilation
• eslint for linting
• prettier for formatting
• make for running tasks and managing compilation
• github actions for running lint on code changes
• http-server for serving the site in development
• nodemon for watching files for changes
