Validate data tree

This library aims to validate data structures (input object, possibly with nested objects and arrays), by the mean of data structures (the schema).

Usable in the server and the browser seamlessly (as long as you use a compiler like babel)

Get started

Because "un exemple vaut mille mots":

const{ validate }=require('validate-data-tree')constschema={email: {// if allowNull is enabled and the input is null, validators are not calledallowNull: true,validate: {isEmail: true,},},phone: {allowNull: true,},settings: {type: 'object',schema: {optinNewsletter: {validate: {isBoolean: true,},},},},roles: {type: 'array',schema: {$: {validate: {allowedKeys: ['name','until'],},},name: {validate: {len: [3,50],matches: '^[A-Z]+$',},},until: {allowNull: true,validate: {isDate: true,},},},},$: {validate: {// custom predicate, name it the way you want (here "oneOf")// and it will be called with the value of the input// at the path corresponding to the key// (here $ corresponds to the whole object)oneOf: ({ email, phone })=>email||phone,// disallow extra keysallowedKeys: ['email','phone','settings','roles'],},},};constbadUserInput={// missing an email or a phoneroles: [// this one is ok{name: 'ADMIN',until: '2019-12-05T16:42:40.069Z'},{name: 'toolongandlowercase',extraKey: 'aïe'},],settings: {optinNewsletter: 'should be a boolean',},};try{validate(badUserInput,schema);}catch(e){// e is an instance of ValidationErrorse.errors.forEach((err)=>{// instance of ValidationErrorItemconst{

Available validators

This library is inspired from the npm packages validator.js and the extensions provided by sequelize (the DSL is compliant)

Then you can refer to their docs:

Added validators:

validator keyarguments
allowedKeysarray of keys (ex: ['k1', 'k2'])
size[min, optional max] (ex: [1, 5] or [1] for unbound maximum size)

Available validators
This library is inspired from the npm packages validator.js and the extensions provided by sequelize (the DSL is compliant)
Then you can refer to their docs:
Added validators:
validator keyarguments
allowedKeysarray of keys (ex: ['k1', 'k2'])
size[min, optional max] (ex: [1, 5] or [1] for unbound maximum size)

Validate data tree
This library aims to validate data structures (input object, possibly with nested objects and arrays), by the mean of data structures (the schema).
Usable in the server and the browser seamlessly (as long as you use a compiler like babel)
