Programmatically add scripts to package.json with npm-add-script

Recently I needed to automate the addition of the addition of a script defined in a package.json‘s scripts section. To do this I used npm-add-script (an older, but still functioning project), along with the aforementioned npx.

For example, to add a script labelled start with the contents webpack-dev-server --config ./config/webpack.config.babel.js --env.MODE=development --open --hot, I use:

npx npm-add-script \
  -k "start" \
  -v "webpack-dev-server --config ./config/webpack.config.babel.js --env.MODE=development --open --hot" \
  --force

Using the --force I enforce overwriting of any existing start script.

Did this help you out? Like what you see?
Thank me with a coffee.

I don\'t do this for profit but a small one-time donation would surely put a smile on my face. Thanks!
