Monaco as easy to use UI components

uwu simple-monaco components

These are components that wrap Microsoft's great Monaco editor (from vscode!) for the primary web UI frameworks, with a unified API.

Scroll down for generic docs, all props are reactive, comes with typescript defs/source when applicable.

Packages

pkg	src	npm
react	packages/react	@uwu/monaco-react
vue	packages/vue	@uwu/monaco-vue
svelte	packages/svelte	@uwu/monaco-svelte
solid	packages/solid	@uwu/monaco-solid
voby	packages/voby	@uwu/monaco-voby

Important notes

You may use any theme from here by name.

You can use monaco from an npm package by passing it as noCDN. This will only do anything on the first render of any <Monaco>, and will apply to all later uses of the component.

If you do not do this, monaco will just be loaded from jsDelivr.

To learn how the loading process works more in depth, please check the docs for @uwu/simple-monaco-core.

API

A UI component for the relevant framework is default exported. It does not take children and has the following props:

value (REQUIRED)

The current text value of the editor.

framework	type	notes
react	string
vue	N/A	use v-model
svelte	Writable<string>	must be a svelte store
solid	string
voby	Observable<string>

valOut

The setter of the state/signal.

framework	type	notes
react	(string) => void
vue	N/A	use v-model
svelte	N/A	use the value store
solid	Setter<string>
voby	N/A	Observable<> is writable

lang (REQUIRED)

The programming language to use. Influences highlighting, completion, etc.

type	notes
string

theme

The colour theme to use to highlight code. As mentioned before, a theme from here by name, a theme object and name, or url to a theme.

All instances must share the same theme for weird Monaco reasons.

type	notes
string | [string, IStandaloneThemeData]

readonly

When set, the user cannot edit the contents of the editor. Setting value works fine.

type	notes
boolean

height

Sets the height of the monaco editor.

type	notes
string	defaults to 30rem

width

Sets the height of the monaco editor.

type	notes
string	defaults to 20rem

otherCfg

Other configuration options to pass to the monaco editor (eg autolayout)

type	notes
core.OtherCfg	defaults to {}

noCDN

Pass an instance of the monaco library instead of loading it from jsDelivr.

type	notes
Monaco

filename

This is used to set the "URL" of the model open in the editor. Mostly this isnt necessary, but is sometimes necessary for things such as enabling JSX support in the typescript language via extension. This doesn't show in the UI as monaco does not have the vscode tabbar.

This will be constructed into a URL for you of the form inmemory://sm-model/.... (The default URLs used by monaco are inmemory://model/1, then 2, 3, etc).

type	notes
string

editorRef

An escape hatch that gives you out the editor instance used by the component. This is to keep this simple library from becoming too big as if you need this your case is likely not simple.

With this you are god.

framework	type	notes
react	((core.WrappedEditor) => void) | Ref<core.WrappedEditor>
vue	N/A	use the editorRef event.
svelte	((core.WrappedEditor) => void) | Writable<core.WrappedEditor>	must be a svelte store
solid	((core.WrappedEditor) => void)
voby	((core.WrappedEditor) => void)	ObservableLike is compatible with this signature

simple-monaco's Issues

Loading theme resource error due to cross-origin policy

I'm using your Monaco Editor plugin for solidjs, worked perfectly until recently. Seems broken on loading theme resource with error message in browser console:

[Error] Failed to load resource: Cross-origin redirection to https://esm.sh/[email protected]/themes/Dracula.json denied by Cross-Origin Resource Sharing policy: Origin [my site host] is not allowed by Access-Control-Allow-Origin. Status code: 301 (Dracula.json, line 0)

Seems esm.sh has changed their cross-origin policy?

The `noCDN` config not exists in solid package

As title.
