Resolving react dependency issues, vulnerabilities, warnings, conflicts and different versions - reactjs

Question

I am trying to:
Fix the dependency issues that arise in my react app
Understand why they are happening
Discover how to best approach these kind of issues to address them properly, without doing anything undesirable (such as hiding the warnings, downgrading, using legacy dependencies, etc)
I want to be able to run npm install and for everything to run perfectly.
To better explain my issue, running npm install returns the following:
npm WARN ERESOLVE overriding peer dependency
npm WARN While resolving: react-side-effect#1.2.0
npm WARN Found: react#18.2.0
npm WARN node_modules/react

Run `npm audit` for details.
Which suggests running the audit command, and hence npm audit returns this:

I can get rid of most errors by running this: npm install --legacy-peer-deps - an undesirable command - which still returns some vulnerability warnings:
removed 57 packages, and audited 1516 packages in 7s
223 packages are looking for funding
run `npm fund` for details
9 vulnerabilities (3 moderate, 6 high)
To address all issues (including breaking changes), run:
npm audit fix --force
Run `npm audit` for details.
So I am a little stuck as to how to fix these issues properly.
Here is my package.json file:

Being prompted with 9 vulnerabilities makes me concerned that something is not right. From my understanding (which may be incorrect), I am assuming that some packages require a version of react that is older than the current version (might be 18 or something), which makes me assume that downgrading might fix them, but then the consequence of that is presumably I’ll never be able to update my version of react, which would suck. Downgrading also does not feel right.
This might be relevant: I am also getting this warning in the JS console even though componentWillMount is not being used, which makes me believe that an outdated library is using it.
Does anyone know why these errors keep occurring, and how to actually fix or at least go about them properly, without having to downgrade or do anything that’s undesirable? And should I worry about these issues? Is it common to see issues after an npm install?
Note that moving react-scripts into devDependencies does nothing, as suggested by this post.

Answer 1

This is how you should read dependency issues:
// this line states that there's an issue with a 'peer' dependency which is a dependency of your dependency. 'overriding' means you explicitly specified a dependency version higher than a peer dependency
npm WARN ERESOLVE overriding peer dependency
//this is the dependency that has an issue
npm WARN While resolving: react-side-effect#1.2.0
// this is what was found in your project
npm WARN Found: react#18.2.0
npm WARN node_modules/react
npm WARN react#"^18.2.0" from the root project
npm WARN 9 more (#fortawesome/react-fontawesome, ...)
npm WARN
// this is what your failed dependency wants react that is no more than version 16, you specified version 18 explicitly which is where the conflict occurs
npm WARN Could not resolve dependency:
npm WARN peer react#"^0.13.0 || ^0.14.0 || ^15.0.0 || ^16.0.0" from react-
side-effect#1.2.0
//these are the modules that your dependency uses that requires the above version
npm WARN node_modules/react-document-meta/node_modules/react-side-effect
npm WARN react-side-effect#"^1.1.0" from react-document-meta#3.0.0-beta.2
npm WARN node_modules/react-document-meta
npm WARN
npm WARN Conflicting peer dependency: react#16.14.0
npm WARN node_modules/react
npm WARN peer react#"^0.13.0 || ^0.14.0 || ^15.0.0 || ^16.0.0" from
react-side-effect#1.2.0
npm WARN node_modules/react-document-meta/node_modules/react-side-effect
npm WARN react-side-effect#"^1.1.0" from react-document-meta#3.0.0-
beta.2
// this is the named dependency in your file that causes the issue
npm WARN node_modules/react-document-meta
Now that we know that react 18 does not work with react-document-meta
we should either go down to the required version and again repeat the process
or
lift up the dependency version and hope that the newer version has a fix
if we look at npm registry for the dependency we can see that the module hasnt been last published 4 years ago, so lifting the version up from this wont be possible. [Looking at the github project page people have similar issues] (https://github.com/kodyl/react-document-meta/issues/48) and recommend moving to react-helmet.
in your case we can revert react 18 to 16 latest and continue using it or transition to using something else as theres no choice unless you want to fork the dependency and work on it yourself.
further:
npm audit describes known issues with the node packages that you are using, you can take a look and see if any of the deployed dependencies have significant issues to your work then you should try and lift them up, otherwise you can ignore. Sometimes dependencies cannot be lifted up and you will have to change to using something else as its not being maintained anymore.
npm fix will attempt automatically updating those vulnerable dependencies but fails in your case as your version mismatch prevents it from proceeding.
you should look into specifying npm versions and allow for minor versions or later versions automatically https://docs.npmjs.com/about-semantic-versioning
you can run npm outdated to check for outdated node versions in your code then npm update to attempt updating versions
if you modify the package.json manually without doing npm add or npm update then theres no dependency checking which can cause issues like yours, I'd recommend to always use npm add <name>, npm uninstall <name> and npm update <name> to avoid issues
finally this is a fixed package.json (working on my machine but may not work code-wise), I'd suggest upgrading everything and moving to react-helmet
