Api reference

app.yup

Original yup

app.setYupLocale(locale: string | object)

Language setting

// set by string
app.setYupLocale('mars');

// set by object
app.setYupLocale({
  number: {
    min: 'too min',
  },
});

ctx.validate(rules: object[, values: object = null , options: object = null])

Async validate. In order to allow asynchronous custom validations all (or no) tests are run asynchronously. A consequence of this is that test execution order cannot be guaranteed. ref: yup-doc

• rules: validate rules
• values: validate data, default ctx.request.body
• options: this will override the options in the config.

ctx.validateSync(rules: object[, values: object = null , options: object = null])

Sync validate

• rules: validate rules
