code-client-go

A library that exposes scanning capabilities for Snyk Code that can be used in the Snyk CLI as well as Snyk IDE plugins using the Snyk Language Server.

Installation

$ go get github.com/snyk/code-client-go

Usage

HTTP Client

Use the HTTP client to make HTTP requests with configured retriable codes and authorisation headers for Snyk Rest APIs.

You can either configure the client using the functional options pattern provided or by implementing the interfaces.

Provide a net/http.Client factory to customize the underlying HTTP protocol behavior (timeouts, etc).

import (
    "net/http"

    "github.com/rs/zerolog"
    codeClientHTTP "github.com/snyk/code-client-go/http"
    codeClientObservability  "github.com/snyk/code-client-go/observability"
)

logger := zerlog.NewLogger(...)
instrumentor := codeClientObservability.NewInstrumentor()
errorReporter := codeClientObservability.NewErrorReporter()
httpClient := codeClientHTTP.NewHTTPClient(
    func() *http.Client {
        return &http.Client{
            Timeout: time.Duration(1) * time.Second,
        }
    },
    codeClientHTTP.WithRetryCount(1),
    codeClientHTTP.WithLogger(logger),
    codeClientHTTP.WithInstrumentor(instrumentor),
    codeClientHTTP.WithErrorReporter(errorReporter),
)

The HTTP client exposes a Do function.

Target

Use the target to record the target of a scan, which can be either a folder enhanced with repository metadata or a repository.

import (
    codeClientScan  "github.com/snyk/code-client-go/scan"
)

target, _ := codeClientScan.NewRepositoryTarget(path)

target, _ := codeClientScan.NewRepositoryTarget(path, codeClientScan.WithRepositoryUrl("https://github.com/snyk/code-client-go.git"))

Tracker Factory

Use the tracker factory to generate a tracker used to update the consumer of the client with frequent progress updates.

The tracker either exposes an interface with two Begin and End functions or an implementation that doesn't do anything.

import (
    codeClientScan  "github.com/snyk/code-client-go/scan"
)

trackerFactory := codeClientScan.NewNoopTrackerFactory()

tracker := trackerFactory.GenerateTracker()
tracker.Begin()
...
tracker.End()

Configuration

Implement the config.Config interface to configure the Snyk Code API client from applications.

Code Scanner

Use the Code Scanner to trigger a scan for a Snyk Code workspace using the Bundle Manager.

The Code Scanner exposes two scanning functions: UploadAndAnalyze (which supports Code Consistent Ignores) and UploadAndAnalyzeLegacy. These functions may be used like this:

import (
    codeClient  "github.com/snyk/code-client-go"
)

config := newConfigForMyApp()
codeScanner := codeClient.NewCodeScanner(
    httpClient,
    config,
	codeClient.WithTrackerFactory(trackerFactory),
    codeClientHTTP.WithLogger(logger),
    codeClientHTTP.WithInstrumentor(instrumentor),
    codeClientHTTP.WithErrorReporter(errorReporter),
)
if useCodeConsistentIgnores() {
    codeScanner.UploadAndAnalyze(context.Background(), requestId, target, channelForWalkingFiles, changedFiles)
} else {
    codeScanner.UploadAndAnalyzeLegacy(context.Background(), requestId, target, shardKey, files, changedFiles, statusChannel)
}

Observability

Under ./observability we have defined some observability interfaces which allows consumers of the library to inject their own observability implementations as long as they follow the defined interfaces.

Contributing

To ensure the long-term stability and quality of this project, we are moving to a closed-contribution model effective August 2025. This change allows our core team to focus on a centralized development roadmap and rigorous quality assurance, which is essential for a component with such extensive usage.

All of our development will remain public for transparency. We thank the community for its support and valuable contributions.

Getting Support

GitHub issues have been disabled on this repository as part of our move to a closed-contribution model. The Snyk support team does not actively monitor GitHub issues on any Snyk development project.

For help with the Snyk CLI or Snyk in general, please use the Snyk support page, which is the fastest way to get assistance.
