DDF validator

The complete solution for validating DDF File.

• Installation
• Quick Start

Installation

npm install @deconz-community/ddf-validator

Quick Start

You can validate all DDF in a specefic directory using the example below. The validate method will return the validated data or will throw a Zod Error. You can use the package zod-validation-error to format the error for the user.

Example :

import { readFile } from 'node:fs/promises'
import glob from 'fast-glob'
import { fromZodError } from 'zod-validation-error'
import { createValidator } from '@deconz-community/ddf-validator'

(async () => {
  const validator = createValidator()

  const genericFiles = await glob('test-data/generic/**/*.json')
  const ddfFiles = await glob('test-data/**/*.json', {
    ignore: '**/generic/**',
  })

  const genericFilesData = await Promise.all(genericFiles.map(
    async (filePath) => {
      const data = await readFile(filePath, 'utf-8')
      const decoded = JSON.parse(data)
      return { path: filePath, data: decoded }
    },
  ))

  // Sort to load consts first
  genericFilesData.sort((a, b) => a.data.schema.localeCompare(b.data.schema))

  genericFilesData.forEach((file) => {
    try {
      const result = validator.loadGeneric(file.data)
      console.log(`Loaded generic file${file.path}`)
    }
    catch (error) {
      console.error(`Error while loading file ${file.path} : ${fromZodError(error).message}`)
    }
  })

  ddfFiles.forEach((filePath) => {
    const data = await readFile(filePath, 'utf-8')
    const decoded = JSON.parse(data)
    try {
      const result = validator.validate(decoded)
      console.log(`Validated file ${file.path}`)
    }
    catch (error) {
      console.error(`Error while validating file ${file.path} : ${fromZodError(error).message}`)
    }
  })
})()

API

createValidator()

Main function to validate the DDF data object.

Arguments

• generics - : GenericsData; Base generic data to validate DDF.

Return

Return a new validator instance.

Example

import { createValidator } from '@deconz-community/ddf-validator'

const validator = createValidator({
  attributes: ['attr/id']
  manufacturers: { "$MF_FOO": "Foo inc." }
  deviceTypes: { "$TYPE_COLOR_LIGHT": "Color light" }
})

validator.generics

Currently loaded generics.

Return

• generics - : GenericsData; Generic data to validate DDF.

validator.loadGeneric()

Load generic data from an object. Support files with schema constants1.schema.json, constants2.schema.json, resourceitem1.schema.json and subdevice1.schema.json.

Arguments

• data - : object; File data.

Return

• data - : object; File data.

Or throw Zod Error

Example

import { createValidator } from '@deconz-community/ddf-validator'

const validator = createValidator()
validator.loadGeneric({
  "schema": "constants1.schema.json",
  "manufacturers" : {
    "$MF_FOO": "Foo inc."
  },
  "device-types": {
    "$TYPE_COLOR_LIGHT": "Color light"
  }
})

validator.validate()

Validate DDF data from an object. Support files with schema constants1.schema.json, constants2.schema.json, resourceitem1.schema.json, subdevice1.schema.json and devcap1.schema.json. Make sure to load any need generic first.

Arguments

• data - : object; File data.

Return

• data - : object; File data.

Or throw Zod Error

Example

import { createValidator } from '@deconz-community/ddf-validator'

const validator = createValidator()
validator.validate({
  "schema": "constants1.schema.json",
  "manufacturers" : {
    "$MF_FOO": "Foo inc."
  },
  "device-types": {
    "$TYPE_COLOR_LIGHT": "Color light"
  }
})

validator.bulkValidate()

Validate both generic and DDF data from two arrays

Arguments

• genericFiles - : FileDefinition[]; Generic files data.
• ddfFiles - : FileDefinition[]; DDF files data.
• callbacks - : object; Options.
  • onSectionStart - : function; Called when a section start.
  • onSectionProgress - : function; Called when a section progress.
  • onSectionEnd - : function; Called when a section end.

Return

• errors - : FileDefinitionWithError[]; File definition with errors.

Example

validator.bulkValidate(genericFiles, ddfFiles, {
  onSectionStart: (type, total) => {
    spinner.start(chalk.blue(`Parsing ${typeFilesText(type, total)} 1 of ${total}`))
  },
  onSectionProgress: (type, current, total) => {
    spinner.text = chalk.blue(`Parsing ${typeFilesText(type, total)} ${current} of ${total}`)
    spinner.render()
  },
  onSectionEnd(type, total, errorFiles) {
    if (errorFiles.length === 0)
      return spinner.succeed(chalk.green(`No errors found in ${files.length} ${typeFilesText(type, total)}`))

    spinner.fail(chalk.red(`Found ${errorFiles.length} ${plural('error', 'errors', errorFiles.length)} in ${files.length} ${typeFilesText(type, total)}`))

    errorFiles.forEach(({ path, error }) => {
      let message = ''
      try {
        message = fromZodError(error, {
          issueSeparator: '\n    ',
          prefix: null,
        }).message
      }
      catch (e) {
        message = error.toString()
      }
      console.log(`  ${chalk.cyan('File:')}`, path)
      console.log(`    ${chalk.red(message)}`)
    })
  },
})

validator.getSchema()

Return Zod schema with loaded generic data.

Return

• schema - : ZodType; Zod Schema.

Example

import { createValidator } from '@deconz-community/ddf-validator'
import { zodToJsonSchema } from 'zod-to-json-schema'

const validator = createValidator()
const schemaJson = zodToJsonSchema(validator.getSchema(), 'DDF')

Type definition

DDF

The type definition of a valid DDF file. Contain union type for constants1.schema.json, resourceitem1.schema.json, subdevice1.schema.json and devcap1.schema.json.

Example

import type { DDF } from '@deconz-community/ddf-validator'

const data = {} as DDF
