Or with a context:

featureClient.features("my.feature.*", {client: "ragnard.lodbrock@gmail.com"}).then(tree => {
  tree.should.be.deep.equal({
    "my": {
      "feature": {

  console.log('The experiment is ', experiment);
});

Get experiments as tree

experimentsClient.experiments("my.experiment.*", "ragnard.lodbrock@gmail.com").then(tree => {
  //Empty json if the experiment doesn't exists 
  console.log('The experiment is ', experiment);
  tree.should.be.deep.equal({
    "my": {
      "experiment": {
        "id": {
          "variant": "A"
        },
        "id2": {
          "variant": "B"
        }
      }
    }
  })
});

Get a variant

experimentsClient.variantFor("my.experiment.id", "ragnard.lodbrock@gmail.com").then(variant => {
  //Empty json if the variant doesn't exists 
  console.log('The variant is ', variant);

Express proxy

You use express as a proxy to expose Izanami to the client side.

const app = express();
 
Izanami.expressProxy({

  featureClient, // Optional
  experimentsClient, // Optional
  configClient, // Optional
  app, // Express app 
  path: 'my.namespace.*' // The pattern to filter experiments, configs and features
});
