json.encode() function

json.encode() converts a value into JSON bytes.

This function encodes Flux types as follows:

  • time values in RFC3339 format
  • duration values in number of milliseconds since the Unix epoch
  • regexp values as their string representation
  • bytes values as base64-encoded strings
  • function values are not encoded and produce an error
Function type signature
(v: A) => bytes
For more information, see Function type signatures.



(Required) Value to convert.


Encode a value as JSON bytes

import "json"

jsonData = {foo: "bar", baz: 123, quz: [4, 5, 6]}

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
