svelte-window-variables

This preprocessor should only be used as a last resort of if you have lost all sense of reason.

svelte-window-variables will attach all component methods to the window object (when it exists) to give easy access to private component methods. Do no use this unless you have exhausted all other possibilities but if you have to...

Install it

npm i --dev svelte-window-variables

Use it

In your rollup config:

import { attachToWindow } from 'svelte-window-test';
 
const test = process.env.AM_I_THE_TEST_ENV;
 
export default {
  input: __dirname + '/src/main.js',
  output: {
    ...outputOptions,
  },
  plugins: [
    svelte({
      preprocess: attachToWindow(test, 'boom'),
      ...otherSvelteConfig,
    }),
    ...otherPlugins,
  ],
};

In your component:

<script test="name">
 function someFunction() {
   console.log('boo');
 }
</script>

When svelte-window-variables encounters a test attribute on the script it will parse the file and attach any top level functions to the window object. These methods will be available on an object window.__test__. The name you pass into the test attribute will be the property in which these methods are stored. In the above example someFunction can be accessed like so: window.__test__.name.someFunction().

Only top level functions will be available, nested functions will not be attached to the window.

attachToWindow(shouldItRun, attributeName)

attachToWindow only take two parameters:

• shouldItRun - boolean - should the preprocessor be enabled? Tell it. This is required.
• attributeName - string - if you want a custom attribute name because of some conflict, you can pass it here. Defaul: 'test'.
