Introducing Socket Optimize
We're excited to introduce Socket Optimize, a powerful CLI command to secure open source dependencies with tested, optimized package overrides.
@contrast/core
Advanced tools
@contrast/core
Discovers Contrast configuration data (yaml, env vars, etc) and preconfigures a common set of APIs to be used for agent and tooling development.
The module exports a factory function.
const core = require('@contrast/core')();
Logging
core.logger.info('...');
See more about the @contrast/logger
service here.
Monkey-patching
core.patcher.patch(res, 'end', {
name: 'http.ServerResponse.end',
patchType: 'http-things',
pre(data) {
// ...
}
});
See more about the @contrast/patcher
service here.
Code rewriting
core.rewriter.addTransforms({
CallExpression(path, state) {
// ...
};
});
core.rewriter.rewrite('function() { ...');
See more about the @contrast/rewriter
service here.
Dependency hooks
core.depHooks.resolve({ name: 'http' }, http => {
// implemention details
});
See more about the @contrast/dep-hooks
service here.
Models and factories
The construction of model data can rely on configuration and therefore can be stateful. So, we provide the models and their factories as services that can be used by consumers as if static.
// stackframe filtration is configurable, thus stateful
const snap = core.models.StacktraceFactory.createSnapshot();
const frames = snap();
See more about the @contrast/models
service here.
Report messages
// configuration will tell which reporters become active
core.reporters.install();
core.messages.emit('ProtectInputTracingEvent', { ... });
See more about the @contrast/reporter
service here.
Other stuff
There are some utility-type functions that rely on configuration state.
// This uses core.config.stack_trace_filters (new to v5)
core.isAgentPath('/foo');
@contrast/agentify
: Integrate core services and instrumentation into an application. See more here.FAQs
