My client is requesting the dependencies of our projects, including the library name and github/NPM URL. Currently, I am using 'npm ll' command to retrieve this information for each project, but the output is in a tree structure. Is there a way to convert this output into a table format?
I have searched through the documentation of 'npm ll' command, but I couldn't find any information on changing the output to a table.
If everything else fails, you always have the option to extract the necessary information using jq:
npm list --json | jq -r 'recurse(.dependencies[]) | [.name, .version, .repository.url?] | @csv'An example of the result:
"express","4.16.4","git+https://github.com/expressjs/express.git"
"accepts","1.3.5","git+https://github.com/jshttp/accepts.git"
"mime-types","2.1.22","git+https://github.com/jshttp/mime-types.git"
"mime-db","1.38.0","git+https://github.com/jshttp/mime-db.git"
"negotiator","0.6.1","git+https://github.com/jshttp/negotiator.git"
This script provides a solution that may not directly answer the question, but it does offer a way to manipulate the output for better readability. Take a look at the following bash script:
#!/bin/bash
# list packages and remove tree structure prefix + "deduped" suffix (keep only module@version)
data=($(npm ls | sed 's/^[┬├│─└ ]*//g' | sed 's/deduped$//g'))
for module in ${data[*]}
do
# split on @ only when it separates module and version
# (not the @ prefix on @username/module@version)
split=($(echo $module | sed -r 's/^(.+)@/\1 /'))
# an example display
printf "%-30s%10s https://www.npmjs.org/packages/%s\n" ${split[0]} ${split[1]} ${split[0]}
done
