Minor Changes

• A new optional field added to the pnpm section of package.json: packageExtensions. The packageExtensions fields offer a way to extend the existing package definitions with additional information. For example, if react-redux should have react-dom in its peerDependencies but it has not, it is possible to patch react-redux using packageExtensions:

  {
    "pnpm": {
      "packageExtensions": {
        "react-redux": {
          "peerDependencies": {
            "react-dom": "*"
          }
        }
      }
    }
  }

  The keys in packageExtensions are package names or package names and semver ranges, to it is possible to patch only some versions of a package:

  {
    "pnpm": {
      "packageExtensions": {
        "react-redux@1": {
          "peerDependencies": {
            "react-dom": "*"
          }
        }
      }
    }
  }

  The following fields may be extended using packageExtensions: dependencies, optionalDependencies, peerDependencies, and peerDependenciesMeta.

  A bigger example:

  {
    "pnpm": {
      "packageExtensions": {
        "express@1": {
          "optionalDependencies": {
            "typescript": "2"
          }
        },
        "fork-ts-checker-webpack-plugin": {
          "dependencies": {
            "@babel/core": "1"
          },
          "peerDependencies": {
            "eslint": ">= 6"
          },
          "peerDependenciesMeta": {
            "eslint": {
              "optional": true
            }
          }
        }
      }
    }
  }
