Browser support

This library will always have the previous year as its target. For 2021 for example the target will be ES2020. It always provides both a UMD (.js) and .mjs version. If you want to support legacy browsers, please use the feature of your bundler to transpile dependencie. In case of webpack and babel (give vite a try, it's awesome) you'll have to install corresponding plugins such as babel-plugin-proposal-optional-chaining and include the dependency from node_modules which is normally entirely excluded from being processed.

I do this to provide maximum flexibility and give those who target ESNext a chance to make full use of how this library is bundled. Everything else is just a matter of configuration :)

Is this library the right choice for me?

Viselect primarily focuses on being a high-performant engine to select elements with various boundaries, behaviours and modes in your browser. Viselect is to "full-blown libraries" what is popper.js to tippy.js - the core of your feature / of another library.

Development

Use the following commands to work on this locally (we use lerna to manage this):

• npm run dev - Spawns a dev-server for all packages. Every framework-dependend package is bundled with the vanilla version.
• npm run build - Builds all packages in parallel.
• npm run lint:fix - Lints and fixes all errors in all packages.

For the development servers vite is used. It's superb, you should give it a try. To bundle it we use rollup (which is btw also used by vite behind the scenes) to have full control over how the bundle looks like.

Releasing a new version

This project is managed via lerna. To bump the version and publish a new one run the following commands:

• lerna version
• lerna publish from-package
