Info about node exports field support: version ranges, categories, etc.

Categories

- pre-exports: versions before node supported exports in any way (< 12.17)
- broken: versions that have a broken exports implementation. These only support the string form, and array fallbacks. (13.0 - 13.2)
- experimental: versions where exports support was experimental. These only support the “default” condition in the object form. (13.3 - 13.6)
- conditions: the first versions where exports support was unflagged. (13.7 - 13.12)
- broken-dir-slash-conditions: conditions, but directory exports (ending in ./) are broken in these versions (12.17 - 12.19 || ^13.13 || 14.0 - 14.12)
- patterns: support for “patterns” was added in these versions, and directory exports (ending in ./) are broken (^12.20 || 14.13 - 14.18 || 15.x || 16.0 - 16.8)
- pattern-trailers: support for “pattern trailers” was added in these versions (^14.19 || 16.9 - 16.13)
- pattern-trailers+json-imports: pattern-trailers, and JSON can be imported (^16.14)
- pattern-trailers-no-dir-slash: support for directory exports (ending in ./) was removed for these versions (17.0)
- pattern-trailers-no-dir-slash+json-imports: pattern-trailers-no-dir-slash, and JSON can be imported (17.1 - 19 || 20 - 20.18 || ^21 || 22 - 22.11)
- require-esm: ESM files can be required (23 - 23.5 || 22.12 - 22.17 || ^20.19)
- strips-types: these versions also automatically strip types from typescript files, for both require and import (23.6 - 25.3 || ^22.18)
- subpath-imports-slash: these versions support #/ subpath imports patterns in the imports field, e.g. "#/": "./src/.js" (>= 25.4)
