Effortlessly convert your JSON Object to JSON Schema, Mongoose Schema, or a Generic template for quick documentation / upstart.
Convert JSON Objects to MySQL Table Schema, JSON Schema, Mongoose Schema, ClickHouse Schema, Google BigQuery, or a Generic template for documentation, code generation, and more.
Install with npm:
$ npm i --save generate-schema
Optionally, add -g
to the above if you want the generate-schema
command line executable.
Usage: generate-schema [options ...] [file]
Common Options:
-h, --help output usage information
-V, --version output the version number
-q, --quiet Skip help message in program output
Mode Options:
-g, --generic Generic JSON Primitives schema output
-j, --json-schema JSON Schema output
-s, --mysql MySQL Table Schema output
-m, --mongoose Mongoose Schema output
-b, --big-query Google BigQuery Schema output
-c, --clickhouse Clickhouse Table Schema output
When no file is specified, generate-schema
enters a REPL mode.
$ generate-schema -b
