CoalesceThe full-stack meta-framework for ASP.NET Core and Vue.

Build what matters. Generate the rest.

Why Coalesce?

Skip the Plumbing

You build Entity Framework data models, domain services, and rich user interfaces. Coalesce generates API controllers, DTOs, TypeScript models, API clients, and more. Focus on delivering value - we'll handle the trivia.

Effortless UX

Generated ViewModels include auto-save, bulk saves, dirty tracking, loading states, and validation — all flowing from your C# model. Ready-made Vue components give you data-driven dropdowns, date pickers, and more, ready to use in your UIs.

Security Included

Apply role-based, row-level, and property-level security with simple declarative attributes or completely custom code — whichever fits the scenario. Security trimming is enforced automatically on every API response.

The Coalesce Workflow

Define Your Models

Write models with Entity Framework. Use attributes to configure behavior, security, and validation. Write service classes for anything that doesn't fit into simple CRUD.

[Create(Roles = "HR")]
[Edit(Roles = "HR,Admin")]
[Delete(DenyAll)]
public class Employee
{
    public int EmployeeId { get; set; }

    [Search]
    public required string Name { get; set; }

    [Search, EmailAddress]
    public string Email { get; set; }

    public DateOnly HireDate { get; init; }
}

Run Code Generation

A single dotnet coalesce command generates everything between your domain models and your UI.

Build Your Experience

Use the generated APIs and TypeScript with the provided Vue components to build custom pages with rich features and full type-safety. Or, start using the full-featured admin pages right away to view and edit data.

vue

<template>
  <c-loader-status :loaders="[employee.$load, employee.$save]">
    <c-input :model="employee" for="name" />
    <c-input :model="employee" for="email" />
    <c-input :model="employee" for="hireDate" />
    <v-btn @click="employee.$save()">Save</v-btn>
  </c-loader-status>
</template>
<script setup lang="ts">
  import { EmployeeViewModel } from "@/viewmodels.g";
  const employee = new EmployeeViewModel();
  employee.$load(1);
</script>

One Model, Full Stack

From a single C# class, Coalesce generates a complete vertical application slice:

You write:

[Edit(Roles = "HR,Admin")]
[Delete(DenyAll)]
public class Employee
{
    public int EmployeeId { get; set; }

    [Search, Required]
    public string Name { get; set; }

    [Search, EmailAddress]
    public string Email { get; set; }

    public DateOnly HireDate { get; init; }

    [Coalesce]
    public async Task SendWelcomeEmail(
        [Inject] IEmailService emailService)
    {
        await emailService.Send(Email, "Welcome!");
    }
}
