create-graphql-server-logging

Adds logging functions to the GraphQL-Server-Generator: create-graphql-server

import { getLogFilename, logger } from 'create-graphql-server-logging';

adds functions:

• getLogFilename
• logger

With getLogFilename it determines the loggers path and filename from your package.json section. The logger function provides a winston logging environment.

Usage

Your server logs now all Graphql requests and nice formatted queries to the log file, which you've defined. This works only with loglevel = debug. It also allows logfile sizes of 5 MB and maximum 5 logfiles.

Installation

yarn add create-graphql-server-logging

In the create-graphql-server project add the following lines to server/index.js, so you are adding the logger to the server's context. Afterwards you can use it for example in your model files with "this.context.log".

...
import { getLogFilename, logger } from 'create-graphql-server-logging'; // <===
const log = logger(getLogFilename()); // <=== here
...
 
app.use('/graphql', (req, res, next) => {
  passport.authenticate('jwt', { session: false }, (err, me) => {
    req.context = addModelsToContext({ db, pubsub, me, UserCollection, log }); // <=== here
    graphqlExpress(() => {
    ...
    ...
    })
  })
});

Add in package.json the following section:

"scripts": {
  ...
},
"config": {										// <===
  "logfile": "log/all-logs-readable.log",		// <===
  "loglevel": "debug",							// <===
  "maxsize": 5,									// <===
  "maxfiles": 5									// <===
},
