Sponge is a powerful development framework that integrates automatic code generation, Gin and GRPC. Sponge has a rich set of code generation commands, and the generated different functional codes can be combined into a complete service (similar to how artificially broken sponge cells can automatically reassemble into a new complete sponge). From development, testing, API documentation to deployment, one-stop project development greatly improves development efficiency and reduces development difficulty, implementation of "low-code way" development projects.


If you are develop web service or microservice with CRUD APIs, you don't need to write any Go code can be compiled and deployed to the linux server, docker, k8s, just need to connect to the database (mysql、mongodb、postgresql、tidb、sqlite) to generate a complete backend service Go code.

If you develop generic web or microservices, just focus on the three core parts of define tables in the database, define api description information in the proto files, fill in business logic code in the generated template files, and the rest of the Go code is automatically generated by sponge.


Sponge Generates the Code Framework

Sponge is mainly based on SQL and Protobuf two ways to generate code, each way has to generate code for different functions. SQL supports databases mysql, mongodb, postgresql, tidb, sqlite.

Microservice framework

Sponge is also a microservices framework, the framework diagram is shown below, which is a typical microservice hierarchical structure, with high performance, high scalability, contains commonly used service governance features, you can easily replace or add their own service governance features.


Performance testing of http and grpc service code created by the microservices framework: 50 concurrent, 1 million total requests.

Key Features


Project Code Directory Structure

The project code directory structure created by sponge follows the project-layout and is structured as follows. Supported repository types are monolithic application single repository (monolith), microservice multi-repository (multi-repo), microservice single repository (mono-repo).

.
├── api            # Directory for exposing external API interfaces, typically containing proto files and generated *.pb.go files. The directory structure is typically in the form `api/xxx/v1`, where v1 indicates the version.

Quick start

Installation sponge

Sponge can be installed on Windows, macOS, Linux and Docker environments. Click here for instructions on installing sponge.

Starting UI service

After installing the sponge, start the UI service:

sponge run

Access http://localhost:24631 in a local browser and manipulate the generated code on the UI page.

If you want to access it on a cross-host browser, you need to specify the host ip or domain name when starting the UI, example sponge run -a http://your_host_ip:24631. It is also possible to start the UI service on docker to support cross-host access, Click for instructions on starting the sponge UI service in docker.
