Parsing And Serializing Large Objects Using JSONStream In Node.js

  • That said, when we went to execute JSON.stringify() on a massive record-set, we were getting the JavaScript error:

    A quick Google search will reveal that this error actually means that the V8 process ran “out of memory” while performing the serialization operation.

  • stringify() methods that provide Node.js Transform streams (aka “through” streams) through which large operations can be broken down into smaller, resource-friendly operations.
  • To test out this module, I’m going to take an in-memory record-set and stream it disk as JSON; then, when the JSON output file has been generated, I’m going to stream it back into memory and log the data to the terminal.
  • But, take note that when reading the data from the file-input stream, each “data” event indicates an individual record in the overall record-set.
  • To be clear, I haven’t yet tried this in our migration project, so I can’t testify that it actually works on massive record-sets; but, from what I can see, JSONStream looks like a really easy way to serialize and deserialize large objects using JavaScript Object Notation (JSON).

Ben Nadel experiments with JSONStream – an npm module that allows for massive objects to be serialized and deserialized as JavaScript Object Notation (JSON) by using Node.js streams to incrementally transform the data.
