NodeJS
The NodeJS buildpack detects
if your build is Node by looking for a package.json
file. If found, the build
will execute the following NPM (or Yarn) commands.
npm installnpm build
If no Procfile is found, a web process will be started with npm start
.
You can customize the node version using the engines field of your package.json
. For example
{"engines": {"node": ">=0.10.3 <15"}}
