Automatically update package.json version and read it in code

Question

I have logger which is displaying some stuff in production and i want to add version to this logger so i got better clue if/when deployment is finished. Is it possible to:

1. Update package.json version on merge
2. Read this version in code and add it to the logger

That will be really helpful

Answer 1

for the second question if you have access to process you can read the version property of package.json like this:

process.env.npm_package_version

for the first question, that is a little tricky, you can use some packages such as husky to run some npm scripts which you already add to package.json .

so you would listen to git hooks such as commit or merge and using pre- or post- scripts to run a command before or after a hook is fired.

so I guess if you can combine these, you would get your desired result
