SCIM-PATCH

RFC7644 SCIM(System for Cross-domain Identity Management) 2.0 implementation of the "Modifying with PATCH" section 3.5.2.

TL;DR

Important things to know, this library can :

• Validate a SCIM Patch query.
• Patch a SCIM resource from a SCIM Patch Query.

Want to have an example on how it works, check this example.

More Details

This library is implementing the 3.5.2. Modifying with PATCH chapter of the SCIM RFC https://tools.ietf.org/html/rfc7644#section-3.5.2.
It will allow you to create a SCIM resources and to patch them using the SCIM Query language.

Validation of a SCIM Query.

import {patchBodyValidation} from 'scim-patch';

const scimBody: ScimPatchOperation = 
{
  'schemas': ['urn:ietf:params:scim:api:messages:2.0:PatchOp'],
  'Operations': [
    {op: 'replace', path: 'name.familyName', value: 'newFamilyName'}
  ]
};

try {
  patchBodyValidation(scimBody);
} catch (error) {
  // Here if there are an error in you SCIM request.
}

Patch a SCIM resource from a SCIM Patch Query.

This implements the PATCH of a SCIM object from a SCIM Query. You should create a valid SCIM resource by extending the ScimResource interface.

export interface ScimUser extends ScimResource {
    schemas: ['urn:ietf:params:scim:schemas:core:2.0:User'];
    userName: string;
    name: {
        familyName: string;
        givenName: string;
    };
    active: boolean;
    emails: Array<{
        value: string;
        primary: boolean;
    }>;
    roles?: Array<{
        value: string;
        type?: string;
    }>;
    meta: ScimMeta & { resourceType: 'User' };
};

After you have created your object you can patch it by calling the scimPatch operation.

const scimUser: ScimUser = {
  schemas: ['urn:ietf:params:scim:schemas:core:2.0:User'],
  userName: '[email protected]',
  name: { familyName: 'user1', givenName: 'user2' },
  active: true,
  emails: [{value: '[email protected]', primary: true}],
  meta: { resourceType: 'User', created: new Date(), lastModified: new Date() }
};

const patch: ScimPatchOperation = { op: 'replace', value: { active: false } };
const patchedUser = scimPatch(scimUser, patch);
// scimUser === patchedUser, see Options section if you want to avoid updating the original object

This particular operation will return :

{ 
  "schemas": [ "urn:ietf:params:scim:schemas:core:2.0:User" ],
  "userName": "[email protected]",
  "name": { "familyName": "user1", "givenName": "user2" },
  "active": false,
  "emails": [{"value": "[email protected]", "primary": true }],
  "meta": { "resourceType": "User", "created": "2019-12-19T14:36:08.838Z", "lastModified": "2019-12-19T14:36:08.838Z" }
}

Options

Mutate Document

By default scimPatch() is updating the scim resource you pass in the function.
If you want to avoid this, you can add an option while calling scimPatch(), it will do a copy of the object and work on this copy.

Your call will look like this now:

const patchedUser = scimPatch(scimUser, patch, {mutateDocument: false});
// scimUser !== patchedUser

Treat Missing as Add

By default scimPatch() will treat as Add a replace operation that targets an attribute that does not exist. If you prefer to throw an error instead, then set treatMissingAsAdd: false

// scimUser has no addresses
 const patch = {
    op: 'replace',
    path: 'addresses[type eq "work"].country',
    value: 'Australia',
};
const patchedUser = scimPatch(scimUser, patch, {treatMissingAsAdd: false});
// patchedUser.addresses[0].country === "Australia"
