Upgrading React version and it's dependencies by reading package.json
I have an existing project, which has react@15 and all it's dependencies according to that. But now I have to upgrade to react@16 along with it's dependencies. Now, the problem is - there are a lot of dependencies and it is very time consuming to identify version of each dependency.
So, I was wondering if there was a way where I could upgrade the versions of React and it's dependencies mentioned in package.json, without manually modifying the package.json file.
Answer
Using npm
Latest version while still respecting the semver in your package.json: npm update <package-name>.
So, if your package.json says "react": "^15.0.0" and you run npm update react your package.json will now say "react": "^15.6.2" (the currently latest version of react 15).
But since you want to go from react 15 to react 16, that won't do.
Latest version regardless of your semver: npm install --save react@latest.
If you want a specific version, you run npm install --save react@<version> e.g. npm install --save [email protected].

Using yarn
Latest version while still respecting the semver in your package.json: yarn upgrade react.
Latest version regardless of your semver: yarn upgrade react@latest.
