Current behavior

You can write any extra properties and they will be just ignored

Expected behavior

nest-cli.json could be validated

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?

You can mistype parameters, i.e. put in wrong place or make a typo, and cli dont warn about it

i.e. I spent some time to figure out what "plugins" must be in compilerOptions

Environment

I would also be happy to see jsonschema for autocomplete in IDE for this file

I'm interested in working on this using either ajv or cfworker if the former doesn't fit our needs.

Are there any particulars to keep in mind while implementing the same @kamilmysliwiec?

[kamilmysliwiec]

PRs are more than welcome @YashKumarVerma! Feel free to proceed with whatever you think is best. Also, I think we should define a configuration JSON schema too https://json-schema.org/learn/getting-started-step-by-step.html (similarly to what Angular does with their CLI configuration file)

[YashKumarVerma]

Sounds good! Also, is there any reference in the current documentation or codebase where I could find the possible configuration variations. (i believe this doesn't exist as of now, just confirming before doing it).

I just made a PR (SchemaStore/schemastore#1947) to add more descriptions to nest-cli.json's properties and I wonder if any member of NestJS can review those changes and figure out any mistakes.

[DevDengChao]

SchemaStore/schemastore#1947 is merged, your IDE (eg: WebStorm) will be able to give you suggestions when writing nest-cli.json if it uses SchemaStore's definition.

Awesome, thank you! Let's also track validation feature here #1427
