Bash utilities for working with NodeJS projects

utils.sh

# Some useful random Bash utils, mostly for working with NodeJS projects. I use `dep` and `findjs` the most. :)
# You can just stuff these in your .bashrc or .zshrc

alias bork='rm -rf ./node_modules && yarn install'

# an actual bork:
# alias bork='find ./node_modules -type d -depth 1 | sort -R | sed 1q | rm -rf'
# simple libre:
# alias libre='find . -type d -name "node_modules" -prune -o -name "package-lock.json" -exec rm {} \;'

# finds files, ignores several types of directories (you might need to modify that):
# e.g. `libre yarn.lock -print` or `libre -d yarn.lock`
libre() {
  local ignores=(node_modules dist es lib server)
  local FIND=(.)
  for i in "${ignores[@]}"; do
    FIND+=(-type d -name "$i" -prune -o)
  done
  FIND+=(-name)
  if [ "$1" = "-d" ]; then
    shift
    FIND+=($1 -exec rm {} \;)
    shift
  fi
  find "${FIND[@]}" "$@"
}

# possibly the most useful utility (beware it ignores the same directories in `libre` function):
# e.g. `findit '*.js' someFunctionName`
findit() {
  libre "$1" -print0 | xargs -0 grep -n "$2"
}
alias findjs="findit '*.js'"

# requires jq tool, `brew install jq`
# regex search of dependencies. super useful in a project directory or a monorepo.
# e.g. `dep react` or `dep ^react$`
dep() {
  libre package.json -exec sh -c "\
    jq -r '.dependencies | keys[]' {} | \
    grep -q \"$1\" && \
    jq -r '.name' {} && \
    jq -r '.dependencies | to_entries | map(select(.key | match(\"$1\"))) | map(\"\t\"+.key+\"@\"+.value) | .[]' {} \
  " \;
}

# the following are useful for pseudo monorepos, where every git repo is in packages/ dir

  for repo in packages/*/; do
    pushd "$repo" >/dev/null
    if [[ -z "$1" ]]; then
      git pull

    fi
    popd >/dev/null

  local name
  for repo in packages/*/; do
    pushd "$repo" >/dev/null
    branch=$(git symbolic-ref --short HEAD)
    name=$(cat package.json | jq -r '.name')
