file-replace-stream

example

var fileReplaceStream = require('file-replace-stream')
 
// ... a short time later
 
aStreamOfSomethingImportant.pipe(fileReplaceStream('tracking-file.txt'))

Every time that aStreamOfSomethingImportant emits, the contents of tracking-file.txt will be updated with the latest emission.

api

fileReplaceStream(filename) -> transformStream

• Writing to transformStream queues a write to filename.
• Data writes will be dropped if they are superseded by others. In practice this should have no consequence.
• Writes are guaranteed to occur in order, so the latest data will always be what is written to filename.
