joi-filelist

This package provides an extension to Joi for FileList types (also works on an array of files)

Usage

Simply import the fileListExtension method and wrap it around Joi

import BaseJoi from 'joi';
import { fileListExtension } from 'joi-filelist';
export const Joi = fileListExtension(BaseJoi);

After wrapping Joi you can simply use it like any other type that is already supported by default.

Example:

import { Joi } from './joi';
const schema = Joi.object({
  files: Joi.filelist()
});

filelist.min

The minimum number of items in the file list

const schema = Joi.object({
  files: Joi.filelist().min(2)
});

Possible validation errors: filelist.min

filelist.max

The maximum number of items in the file list

const schema = Joi.object({
  files: Joi.filelist().max(4)
});

Possible validation errors: filelist.max

filelist.maxsize

The maximum size in bytes for a file.

const schema = Joi.object({
  files: Joi.filelist().maxSize(1024 * 1024 * 1)
});

Possible validation errors: filelist.maxsize

filelist.mimeType

The allowed MIME types for this file list

const schema = Joi.object({
  files: Joi.filelist().mimeType(['image/jpeg', 'image/jpg'])
});

Possible validation errors: filelist.invalid
