Additional Information

In its current state themes will not build or run. If we update the blockly package.json exports to include the /dist folder in the front of the paths( see example below), the themes will build and run but blockly tests will fail and it would likely fail to resolve for anyone attempting to use the package if it were to be published that way.

Example of how to update packages/blockly/package.json:

  "exports": {
    ".": {
      "types": "./index.d.ts",
      "import": "./index.mjs",
      "umd": "./blockly.min.js",
      "default": "./index.js"
    },
    "./core": {
      "types": "./core.d.ts",
      "node": "./core-node.js",
      "import": "./blockly.mjs",
      "default": "./blockly_compressed.js"
    },
    "./blocks": {
      "types": "./blocks.d.ts",
      "import": "./blocks.mjs",
      "default": "./blocks_compressed.js"
    },
    "./dart": {
      "types": "./dart.d.ts",
      "import": "./dart.mjs",
      "default": "./dart_compressed.js"
    },
    "./lua": {
      "types": "./lua.d.ts",
      "import": "./lua.mjs",
      "default": "./lua_compressed.js"
    },
    "./javascript": {
      "types": "./javascript.d.ts",
      "import": "./javascript.mjs",
      "default": "./javascript_compressed.js"
    },
    "./php": {
      "types": "./php.d.ts",
      "import": "./php.mjs",
      "default": "./php_compressed.js"
    },
    "./python": {
      "types": "./python.d.ts",
      "import": "./python.mjs",
      "default": "./python_compressed.js"
    },
    "./msg/*": {
      "types": "./msg/*.d.ts",
      "import": "./msg/*.mjs",
      "default": "./msg/*.js"
    }
  },

A more detailed list of what does and does not work with each version of the blockly package.json:

Needs /dist in exports to work:

• building themes
• npm run start in themes

Needs exports as-is:

• testing blockly

Works in both:

• building blockly
• building docs
• linting blockly
• linting docs
• linting themes (except hackermode, which does not have a lint command)
• testing docs
• format (root level)

TODO

[ ] Resolve issue around /dist folder
[ ] Clarify what workspace-notation looks like for dependencies
