apollo-logger

library0.3.3jsnpmunverified

Apollo Logger is a utility for logging Apollo GraphQL operations, including queries, mutations, subscriptions, and PubSub events. Current version is 0.3.3. The package has low release cadence (last release in 2018). Key differentiators: it provides multiple entry points (LoggingLink for Apollo Link, wrapPubSub for PubSub, formatResponse for Express) to log the full lifecycle of GraphQL requests. It is unmaintained and should be considered for deprecation in favor of modern alternatives like Apollo Server plugins.

Shows how to set up logging for Apollo Link, Express server, and PubSub using Apollo Logger.

import { LoggingLink, wrapPubSub, formatResponse } from 'apollo-logger'; import { ApolloLink, HttpLink } from 'apollo-link'; import { PubSub } from 'graphql-subscriptions'; import express from 'express'; import { graphqlExpress } from 'apollo-server-express'; const logOptions = { logger: console.log }; const link = ApolloLink.from([ new LoggingLink(logOptions), new HttpLink({ uri: '/graphql' }) ]); const app = express(); app.use('/graphql', graphqlExpress({ schema: myGraphQLSchema, formatResponse: formatResponse.bind(logOptions) })); const pubsub = new PubSub(); const wrappedPubSub = wrapPubSub(pubsub, logOptions); app.listen(4000, () => console.log('Server running on port 4000'));

Debug

Known issues

deprecatedPackage is unmaintained since 2018. No updates for modern Apollo Link v2 or Apollo Server v3+.

fix

Consider using Apollo Server built-in plugins or custom logging solutions.

affects: >=0.3.3

gotchaformatResponse expects `this` context bound to logOptions. If not bound, logging may fail.

fix

Use formatResponse.bind(logOptions) when passing to apollo-server-express.

affects: *

gotchawrapPubSub modifies the original PubSub instance in-place; do not use the original after wrapping.

fix

Store the returned wrapped instance and use that for all PubSub operations.

affects: *

gotchaPeer dependencies (apollo-link, graphql-subscriptions, graphql, iterall) must be manually installed; not bundled.

fix

Run: npm install apollo-link graphql-subscriptions graphql iterall

affects: *

Errors

Common errors & fixes

TypeError: Cannot read property 'logger' of undefined

formatResponse called without proper this context binding.

fix

Use formatResponse.bind(logOptions) when passing to graphqlExpress.

Module not found: Can't resolve 'apollo-link'

Missing peer dependency apollo-link.

fix

Run: npm install apollo-link

TypeError: PubSub.wrapPubSub is not a function

Incorrect import of wrapPubSub; may be using default import instead of named.

fix

Use: import { wrapPubSub } from 'apollo-logger';
