This document provides a comprehensive guide to configuring the development environment for the slimtoolkit/slim project. All steps assume that the environment is already set up and that the developer is familiar with the slim project.

Go Module Configuration

The slimtoolkit/slim project uses Go modules, with the module name specified as:

module github.com/slimtoolkit/slim

This configuration directly impacts the Go build output. When running builds, ensure that you do not use the -mod=vendor flag as it is not required for this project.

Build commands will typically look like:

go build

This command compiles the code in the current directory and produces an executable binary.

Test Configuration

When conducting tests, there is a specific build constraint that must be adhered to for certain files. Particularly, files that are relevant for end-to-end (e2e) tests must be invoked with the following build constraint:

// +build e2e

To run the tests associated with these constraints, utilize the following command, ensuring that the e2e tag is specified:

go test -tags e2e ./...

This command will execute all tests that match the e2e build constraint.

Makefile Configuration

The Makefile plays a crucial role in streamlining common development tasks. Here are some key targets that can be leveraged within the Makefile:

Build Target

The build target compiles the project, enabling quick builds:

build:
    go build

Invoke this target using:

make build

Test Target

To run tests seamlessly, the following target can be defined in the Makefile:

test:
    go test -tags e2e ./...

You can run all tests by executing:

make test

Dockerfile Configuration

The Dockerfile provides a mechanism for containerizing the slimtoolkit/slim application. The essential constructs include:

FROM golang:1.17 as builder

WORKDIR /app
COPY . .

RUN go build -o slim github.com/slimtoolkit/slim

This snippet sets up a multi-stage build, with the base image being Go 1.17, specifying the working directory as /app, and copying the application’s source code. Finally, it compiles the application into an executable named slim.

To build the Docker image, the command would be:

docker build -t slimtoolkit/slim .

Conclusion

The configuration of the development environment in slimtoolkit/slim is streamlined through carefully structured Go modules, Makefile targets, and a concise Dockerfile. By adhering to the specified constraints and utilizing provided commands, developers can effectively manage builds and tests in their local setup.
