Discussion on: Why Running `yarn upgrade` Does Not Update My `package.json`

[Sergii Shymko]

Have been using yarn upgrade --exact. The flag forces the command to override package.json no matter how the version constraint is declared.

yarn upgrade react --latest --exact

Actually, discovered that sometimes package.json is not being updated.

Looks like yarn add is more reliable than yarn upgrade:

yarn add react --exact

The downside it will install a new package if it has not been installed yet.

This technique can be used to upgrade all packages in a given scope:

jq -r '.dependencies | keys | .[] | select(startswith("@myscope/"))' package.json | xargs yarn add --exact
