How to use vscode-json-language-server JSON schemas

[matzxrr]

I'm trying to configure the vscode-json-language-server to use JSON schema files.

We should be able to define these schemas so I can get autocomplete / validation for json properties.
Vscode JSON ls Config Docs

Here is my current attempt at getting it to work.

[[language]]
name = "json"
language-servers = ["jsonls"]
formatter = { command = 'npx', args = ["prettier", "--parser", "json"] }

[language-server.jsonls]
args = ["--stdio"]
command = "vscode-json-language-server"

[language-server.jsonls.config]
json = { validate = { enable = true }, format = { enable = true } }
provideFormatter = true

[[language-server.jsonls.json.schemas]]
fileMatch = ["tsconfig.json", "tsconfig.*.json"]
url = "https://json.schemastore.org/tsconfig.json"

Just add this, don't worry about duplicating stuff from the Helix config:

[[language-server.vscode-json-language-server.config.json.schemas]]
fileMatch = ["tsconfig.json", "tsconfig.*.json"]
url = "https://json.schemastore.org/tsconfig.json"

[[language-server.vscode-json-language-server.config.json.schemas]]
fileMatch = [ "package.json" ]
url = "https://json.schemastore.org/package.json"

I have a new question, can this be written in a better way to avoid all the duplication?

I am using Biome to format, it copies Prettier and is much faster:

[language-server]
biome = { command = "biome", args = ["lsp-proxy"] }

[[language]]
name = "json"
language-servers = [ { name = "vscode-json-language-server", except-features = [ "format" ] }, "biome"]

@David-Else did you ever determine if the deduplicated snippet you provided works, or does Helix require using the format from your first snippet?
