@kannan19302/framework

Part of UniERP — an open-source, self-hostable multi-tenant application platform. Repository map · Architecture · Contributing · Security

UniERP's unified frontend framework. Provides a declarative metadata layer: modules describe their resources declaratively, and the framework generates data fetching, validation, navigation, and full list/detail/form views — the same way for every app and module.

Sits above @kannan19302/ui (design system) and below each host app (apps/web, future apps). It is also the shared runtime that Studio-rendered pages should consume — do not fork a second rendering engine.

Layers

Layer	Import	What it does
Metadata	ResourceSchema, FieldDef, ModuleDefinition	Declarative description of a module and its entities
Registry	defineModule, createRegistry	Modules self-register; hosts derive routes/nav from it
Client	ApiClient	One configured HTTP gateway (auth, CSRF, tenant, errors)
Data	useResourceList/Doc, useCreate/Update/DeleteResource	Tenant-scoped TanStack Query hooks with cache invalidation
Schema	buildZodSchema, validateValues	Zod validation generated from FieldDefs + custom validators
Permissions	Guarded, RouteGuard, usePermission	RBAC (module.resource.action) gating for nav, routes, actions, fields
Views	ListView, FormView, DetailView	Schema-driven pages with escape hatches (custom cells, sections, children)

Quick start

1. Define a module (one file per module, e.g. modules/crm.ts):

import { defineModule, defineResource } from '@kannan19302/framework';

const customer = defineResource({
  name: 'customer',
  labelSingular: 'Customer',
  labelPlural: 'Customers',
  endpoint: '/crm/customers',
  titleField: 'name',
  permissions: { read: 'crm.customer.read', create: 'crm.customer.create', update: 'crm.customer.update' },
  status: { field: 'status', tones: { ACTIVE: 'success', CHURNED: 'danger' } },
  fields: [
    { name: 'name', label: 'Name', type: 'text', required: true },
    { name: 'email', label: 'Email', type: 'email', required: true },
    { name: 'type', label: 'Type', type: 'select', options: [
      { value: 'COMPANY', label: 'Company' }, { value: 'INDIVIDUAL', label: 'Individual' },
    ]},
    { name: 'creditLimit', label: 'Credit Limit', type: 'currency', min: 0,
      visibleIf: (v) => v.type === 'COMPANY' },
  ],
  list: { columns: ['name', 'email', 'type', 'status'], searchable: true, pageSize: 25 },
  form: { sections: [{ title: 'General', fields: ['name', 'email', 'type', 'creditLimit'] }] },
});

export const crmModule = defineModule({
  id: 'crm', title: 'CRM', basePath: '/crm',
  resources: [customer],
});

2. Mount the provider once in the host app:

<FrameworkProvider
  api={{
    baseUrl: process.env.NEXT_PUBLIC_API_URL || '/api/v1',
    getToken: () => localStorage.getItem('token'),
    getCsrfToken: () => readCookie('csrf_token'),
    getTenantId: () => activeTenantId,
  }}
  modules={[crmModule]}
  queryClient={existingQueryClient} // or createQueryClient
>
  {children}
</FrameworkProvider>

3. Pages become one-liners:

// /crm/customer — list
<RouteGuard permission="crm.customer.read">
  <ListView resource={customer} onRowClick={(row) => router.push(`/crm/customer/${row.id}`)}
            onCreate={() => router.push('/crm/customer/new')} />
</RouteGuard>

// /crm/customer/[id] — detail (children slot for tabs, history, related lists)
<DetailView resource={customer} id={id} onEdit={() => router.push(`/crm/customer/${id}/edit`)} />

// create / edit
<FormView resource={customer} id={id} onSuccess={(rec) => router.push(`/crm/customer/${rec.id}`)} />

4. Navigation is derived, not hand-written:

const nav = buildAppNav(registry.getModules(), hasPermission);

Conventions

• Tenant safety: every cache key is prefixed with the tenant id from getTenantId(); switching tenants can never surface another tenant's cached rows.
• Permissions: RBAC codes follow module.resource.action. Missing read hides the nav item; RouteGuard blocks the route with a 403 view; Guarded hides buttons/fields.
• Server contract: list endpoints accept page, pageSize, search, sortField, sortDirection plus arbitrary filter params, and return { data, total } (bare arrays and { items, total } also accepted).
• Escape hatches: list.render for custom cells, toolbar/actions/children/footer slots on every view, and all data hooks are usable standalone for fully custom pages.
