# Configuration

The starting point for customization is default.json or its copy local.json where the platform seeks configuration values.


If you want to modify default.json, don't edit it directly but copy the whole file into local.json and start editing that file. Why it should be done that way is explained later in Secret 3. Why use node-config?

We have two local.json files, one of which is for the backend here, and we will look at Secret 2, the other for the frontend.

In vue-storefront-api/config/default.json for the backend you will see :

  "server": {
    "host": "localhost",
    "port": 8080,
    "searchEngine": "elasticsearch"
  • This is where your API backend is defined. The server will listen on server.host:server.port unless it's defined otherwise in your environment variables.

  • server.searchEngine is used in the integration with graphql so please don't change it. jump to code

  "orders": {
    "useServerQueue": false
  "catalog": {
    "excludeDisabledProducts": false
  • orders.useServerQueue allows you to use the queue process when the order API is used to create an order. jump to code

  • catalog.excludeDisabledProducts allows you to skip disabled products when importing products using mage2vs. jump to code

  "elasticsearch": {
    "host": "localhost",
    "port": 9200,
    "protocol": "http",
    "user": "elastic",
    "password": "changeme",
    "min_score": 0.01,
    "indices": [
    "indexTypes": [
    "apiVersion": "5.6"
  • The elasticsearch element is used widely across the whole platform. Considering elasticsearch works as a data store (database), it's natural.

    • The host, port, protocol entries define elasticsearch connection information.
  • user, password are the default credentials of elasticsearch. If you changed the credentials for elasticsearch, please change this accordingly. more info

    • min_score sets a min_score when building a query for elasticsearch. jump to code


      min_score helps you exclude documents with _score less than the min_score value.

    • indices may contain one or multiple indexes. Each index acts as a data store for a storefront. You may add entries to the array with arbitrary names or remove entries from it.

      CAUTION !

      The index name should match the one you use with the data import tool.

    The default values for indices assume you have two additional stores(de, it) in addition to the default store.

    • indexTypes contains values for mapping. You can consider it a table if you take indices as a database.
    • apiVersion defines the elasticsearch version used. The default is 7.1.
  "redis": {
    "host": "localhost",
    "port": 6379,
