How do I find the exact installed version of a package from package.json in an express application in a Fedora distribution?
I could look through package-lock.json but are there an easier way, as it's huge?
I've tried
npm list
but it's not installed and I don't want to install it if is not necessary.
Any easy way of doing this?
For NPM to get a list of package versions you must first cd to the folder where your NPM application is.
Then run (from folder where you run your npm apps)
npm ls --depth=0
If you dont see anything try the command with global setting
npm -g ls --depth=0
-bash: npm: command not found when running above command. I'm looking for a way to not have to install npm as its and elastic beanstalk that "resets" it self when i rebuild it/scale it.
The following script searches the package.json file in the directory where it is executed for the specified package and prints out its version:
# getPackageVersion.sh
# Searches the package.json for a specific package and prints out its version
#
# Usage:
# chmod +x getPackageVersion.sh
# ./getPackageVersion.sh <package_name>
packageName=$1
if [ ! -f ./package.json ]; then
echo "package.json file not found in current directory."
exit
fi
if [ -z "$packageName" ]
then
echo "No package name given."
exit
fi
packageJsonOutput=$(cat package.json | grep "\"$packageName\": \"*\"")
version=(${packageJsonOutput//:/ })
version=${version[1]//\"/}
if [ "$version" == "" ]
then
echo "Package not found."
exit
fi
echo "$version"
chmod +x getPackageVersion.sh
./getPackageVersion.sh <package_name>
$ cd ~/sw/your-project/
$ ./getPackageVersion.sh debug
4.3.1
if you use yarn as package manager, yarn.lock contains the exact version that is resolved during yarn install command run.
