Generates zod schema from JSON string on standard inputs.

Installation

npm install --save-dev @wbydo/zodidien

Usage

Generating a schema

When you type this command...

echo '{"foo": 1234, "bar": "asdf"}' | npx zodidien foobar

This string will be output

const foobarSchema = z.object({
  foo: z.number(),
  bar: z.string(),
});

It reads from standard input and outputs to standard output, so it can be used like this.

pbpaste | npx zodidien foobar

# output
#
# const foobarSchema = z.object({
#    foo: z.number(),
#    bar: z.string()
#});
