What you'll learn

Why

[interpreter]
command = [
    "prybar-nodejs",
    "-q",
    "--ps1",
    "\u0001\u001b[33m\u0002\u0001\u001b[00m\u0002 ",
    "-i"
]

[env]
XDG_CONFIG_HOME = "$REPL_HOME/.config"
PATH = "$REPL_HOME/.config/npm/node_global/bin:$REPL_HOME/node_modules/.bin"
npm_config_prefix = "$REPL_HOME/.config/npm/node_global"

[packager]
language = "nodejs"
  [packager.features]
  packageSearch = true
  guessImports = true
  enabledForHosting = false

[languages]
[languages.javascript]
pattern = "**/{*.js,*.jsx,*.ts,*.tsx,*.json}"
[languages.javascript.languageServer]
start = "typescript-language-server --stdio"

What is evalModules

Module system basics

Benefits of the module system

• Easy to define types
• Composability
• Easy to track dependencies
• Build into various artifacts:
  • Docker container layers
  • Disk images
  • VM tests
