Installation

  1. Download
yarn add strapi-plugin-request-id

or

npm i strapi-plugin-request-id
  1. Enable the plugin

In config/plugins.js, add:

module.exports = ({ env }) => ({
  //...
  "request-id": {
    enabled: true,
  },
  //...
});
  1. Add the request-id middleware:

In config/middlewares.js, add the middleware at the bottom of the list:

module.exports = [
  //...
  "plugin::request-id.request-id",
];

Usage

When a request is received, a unique request id and correlation id are added to it.

These ids have different meanings:

  • request id: Used to track a user's actions on the server only. Each time a request is received, a new request id is generated, even if the associated header is set.
  • correlation id: Used to track a user's actions across multiple services. The correlation id is either set from the headers of the request or generated if none is provided.

☝️ If the header of the request contains the property X-Correlation-Id, this value is used as the correlation id instead generating a new one.


Config

In config/plugins.js:

module.exports = ({ env }) => ({
  //...
  "request-id": {
    enabled: true,
    config: {
      /**
       * Define the header to use to get/set the correlation id.
       */
      correlationIdHeader: "X-Amzn-Trace-Id", // default: "X-Correlation-Id".
    },
  },
  //...
});

Services

/**
 * Get the service "request-id".
 */
strapi.plugin("request-id").service("request-id");

    /**
     * Get the correlation id of the request.
     */
    getCorrelationId(): string;

    /**
     * Get the request id of the request.
     */
    getRequestId(): string;

Examples

Example 1: Logging

The request id and correlation id are automatically logged when a message is logged using the strapi logger.

This code:

const endpoint = (ctx) => {
  const { user } = ctx.state;

  strapi.log.info(`user ${user.id} was there!`);

  ctx.status = 200;
};

Will produce the logs:

{
  "level": "info",
  "message": "user 1 was there!",
  "timestamp": "2022-05-29 17:26:19",
  "x-correlation-id": "e5b97199-9003-4c36-8ead-28186e3f4a4f",
  "x-request-id": "04dd66c9-3d3e-4188-8ae8-32703d864862"
}

You can then track user 1's activity by filtering the logs with x-request-id="04dd66c9-3d3e-4188-8ae8-32703d864862", or accross your services using x-correlation-id.

By default, strapi doesn't display the logs as json in the console. If you want to see the request id and correlation id while developing, create the file config/logger.js and use this configuration:

const { winston } = require("@strapi/logger");

module.exports = {
  transports: [
    new winston.transports.Console({
      level: "silly",
      format: winston.format.combine(
        winston.format.timestamp({ format: "YYYY-MM-DD HH:mm:ss" }),
        winston.format.json()
      ),
    }),
  ],
};

Example 2: Access the Request/Correlation Id of a Request

The request id and correlation id are added to the headers of the response. They can be accessed through the ctx.response object:

const endpoint = (ctx) => {
  const requestIdService = strapi.plugin("request-id").service("request-id");

  const requestId = requestIdService.getRequestId();
  const correlationId = requestIdService.getCorrelationId();

  const res = await fetch(`my-other-service/endpoint`, {
    method: "GET",
    headers: {
      // Add the correlation id when calling an external service.
      "X-Correlation-Id": correlationId
    },
  });

  ctx.body = { data: res.data };
};

Example 3: Customize the Correlation Id Header

By default, the correlation id is associated to the header X-Correlation-Id. It is configurable:

In config/plugins.js:

module.exports = ({ env }) => ({
  //...
  "request-id": {
    enabled: true,
    config: {
      correlationIdHeader: "X-Amzn-Trace-Id",
    },
  },
  //...
});

Now, let's say the server received a request with the header "X-Amzn-Trace-Id": "my-custom-trace-id". It will produce the logs:

{
  "level": "info",
  "message": "user 1 was there!",
  "timestamp": "2022-05-29 17:26:19",
  "x-amzn-trace-id": "my-custom-trace-id",
  "x-request-id": "04dd66c9-3d3e-4188-8ae8-32703d864862"
}

The response will also have the header "X-Amzn-Trace-Id": "my-custom-trace-id".
