Description
Use case
Currently if you want to context in async workflows you have to pass child loggers to the methods you call
const tasks = batch.map(async (id) => {
doWork(id, { logger: logger.createChild() })
})
await Promise.all(tasks)
Solution/User Experience
We could use node's AsyncLocalStorage to save the 'current' logger, and functions could fetch the logger from the store
This could be combined with explicit resource management to allow writing code like
const handler = (event, context) => {
using logger = withContext(context)
const tasks = event.batch.map(doWork)
await Promise.all(tasks)
}
async function doWork(task: Task) {
using logger = withAdditionalKeys({ id: task.id })
await step1(task)
await step2(task)
}
async function step1(task: Task) {
using logger = withAdditionalKeys({ step: "1" )
logger.info()
}
Alternative solutions
This can be built ad-hoc but would be better to include in the library.Acknowledgment
