Bug fixes

• Fix file existence check for non-js files (#96)

Full Changelog: v0.2.7...v0.2.8

v0.2.7

Features

• If the library exports from both "main"/"module" and "exports" fields, but the "exports" field doesn't export the root entrypoint, warn about the inconsistency. When "exports" is defined, it takes the highest priority, so all the library's entrypoint (root and deep) needs to be specified here. (#88)
• Suggest using the "type" field. In Node.js v20.10.0, it introduces a new --experimental-default-type flag to flip the default module system from "CJS-as-default" to "ESM-as-default". It's recommended for libraries to specify the "type" field explicitly to prevent CJS files from being incorrectly interpreted as ESM. This suggestion helps push towards a better ESM experience in the future. (#83)

Full Changelog: v0.2.3...v0.2.4

v0.2.3

Features

• Error if package.json has fields with invalid string, boolean, object, etc type (#73)

• Suggest using the "files" field if detected test or config files are published (#77)

• Warn on "exports" and "browser" object conflict for browser-ish environments (#58)

  For example, given this setup:

  {
    "browser": {
      "./lib.server.js": "./lib.browser.js"
    },
    "exports": {
      ".": {
        "worker": "./lib.server.js",
        "browser": "./lib.browser.js",
        "default": "./lib.server.js"
      }
    }
  }

  When matching the "worker" condition, it will resolve to "./lib.server.js" which is intended to work in a worker environment. However, the "browser" field also has a matching mapping for "./lib.server.js", causing the final resolved path to be "./lib.browser.js". This is usually not intended and causes the wrong file to be loaded.

• Error on invalid JSX extensions, such as .cjsx, .mjsx, .ctsx, and .mtsx (#76)

  These extensions are usually mistaken as ESM and CJS variants of JSX, which is not valid. Instead they should be written in ESM with the .jsx extension instead.

Bug fixes

v0.2.0

Breaking changes

Note: If you're using publint from the CLI, these breaking changes should not affect you.

• publint() now returns an object with messages instead of the messages array directly. This makes way for future APIs where publint will return more information than just messages.

  - const messages = await publint()
  + const { messages } = await publint()

• Rename printMessage API to formatMessage to better reflect it's intent. (#43)

  - import { printMessage } from "publint/utils"
  + import { formatMessage } from "publint/utils"
  
  const { messages } = await publint()
  
  for (const message of messages) {
  - console.log(printMessage(message))
  + console.log(formatMessage(message))
  }

• Remove filePath arg for the FILE_DOES_NOT_EXIST message.

  import type { Message } from "publint"
  import { getPkgPathValue } from "publint/utils"
  
  function messageToString(message: Message, pkg: Record<string, any>) {
    switch (message.code) {
      case "FILE_DOES_NOT_EXIST":
  -     return `The file "${message.args.filePath}" does not exist.`
  +     return `The file "${getPkgPathValue(pkg, message.path)}" does not exist.`
    }
  }

• Remove the import condition for the publint package. This provides a better error message if you call require("publint").

Features

• Improve warnings when the exported "types" condition has an invalid format in ESM or CJS. This ensures your library's types will work in both environments when dual publishing. (#46)

  It affects packages commonly packaged like:

  {
    "exports": {
      ".": {
        "types": "./index.d.ts", <-- only works in CJS
        "import": "./index.mjs",
        "require": "./index.js",
      }
    }
  }

  For more information, visit the rules documentation. This feature is inspired by https://arethetypeswrong.github.io.

Bug fixes

• Suppress warnings when exported JS files using the "exports" field have adjacent .d.ts files and no "types" condition. This follows TypeScript's resolution algorithm. For more information, visit the rules documentation. (#46)

v0.1.16

Bug fixes

• Don't enforce the module condition to precede import per se. It is now ensured to precede require only as otherwise the condition isn't effective (#50)
