      Use Case

      Typescript 5.0

       @types/node                       ^18.11.19  →  ^18.15.11
       @typescript-eslint/eslint-plugin    ^5.55.0  →    ^5.57.0
       @typescript-eslint/parser           ^5.55.0  →    ^5.57.0
       eslint                              ^8.36.0  →    ^8.37.0
       eslint-config-prettier               ^8.7.0  →     ^8.8.0
       prettier                             ^2.8.4  →     ^2.8.7
       tsd                                 ^0.27.0  →    ^0.28.1
       typescript                           ^4.9.5  →     ^5.0.2
      

      User Impact

      None

      Dev Impact

      Faster build times

      Acceptance Criteria

      • Apply the following to the BSON repo as well.

      Implementation Requirements

      This type narrowing issue needs correcting, both Int32 instances and numbers have a .valueOf() function we could invoke so we can remove the the instanceof checking. Which we should not be using instanceof anyway.

      src/cmap/connect.ts(80,5): error TS2365: Operator '>=' cannot be applied to types 'number | Int32' and 'number'.
      src/cmap/connect.ts(84,5): error TS2365: Operator '<=' cannot be applied to types 'number | Int32' and 'number'.
      

      This option is deprecated, we can ignore the deprecation but it is going to be removed in a future minor version, might as well make the removal now.

      tsconfig.json(21,5): error TS5101: Option 'importsNotUsedAsValues' is deprecated and will stop functioning in TypeScript 5.5. Specify compilerOption '"ignoreDeprecations": "5.0"' to silence this error.
      

      In order to continue enforcing the type indicator be used in front of type only imports, we need to start using eslint instead.
      https://typescript-eslint.io/rules/consistent-type-imports

      "@typescript-eslint/consistent-type-imports": [
                "error",
                {
                  "prefer": "type-imports",
                  "disallowTypeAnnotations": false,
                  "fixStyle": "inline-type-imports"
                }
              ],
      

      This will cause a reformat across many imports that didn't follow the rule we thought importsNotUsedAsValues was applying.

      Testing Requirements

      • Our typescript version matrix should be coverage enough.
