TSConfig schema is outdated! does not support ES2023 for compilerOptions.target and lib

[muhammad-fiaz]

Description of the JSON schema.

The current tsconfig.json schema in SchemaStore is outdated and does not allow newer ECMAScript versions such as "ES2023" in the fields:

• compilerOptions.target
• compilerOptions.lib

This results in false validation errors inside editors like VS Code and Microsoft Edge DevTools, even though the latest TypeScript compiler fully supports ES2023+ features.

Examples of the current error shown by VS Code:

'compilerOptions/target' must be equal to one of the allowed values 'ES3, ES5, ES6, ES2015, ES2016, ES2017, ES2018, ES2019, ES2020, ES2021, ES2022, ESNext'. Value found '"ES2023"'. Or 'compilerOptions/target' must match pattern '^([Ee][Ss]([356]|(20(1[56789]|2[012]))|[Nn][Ee][Xx][Tt]))$'. Value found 'ES2023'Microsoft Edge Tools[typescript-config/is-valid](https://webhint.io/docs/user-guide/hints/hint-typescript-config/is-valid/)
Set the JavaScript language version for emitted JavaScript and include compatible library declarations.

These errors occur even though TypeScript 5.x supports ES2023+ targets, because the SchemaStore JSON schema has not yet been updated.

Request
Please update the TSConfig schema to include:

ES2023+

in both compilerOptions.target and compilerOptions.lib.

This will remove false errors in VS Code / Edge Tools and reflect the actual capabilities of modern TypeScript.

Thank you!

Supporting information.

Are you making a PR for this?

No, someone else must create the PR.

Thanks for the report! jsconfig.json will have to be fixed as well.
