  • Handling high-traffic HTTP requests with JSON payloads
    5 projects | /r/golang | 7 Dec 2023
    Since most of the time would be spent decoding json, you could try to cut this time using https://github.com/bytedance/sonic or https://github.com/json-iterator/go, both are drop-in replacements for the stdlib, sonic is faster.
  • A Journey building a fast JSON parser and full JSONPath
    5 projects | news.ycombinator.com | 11 Oct 2023
    We all know the builtin golang JSON parser is slow.

    How about doing comparisons against other implementations?

    Like this one: https://github.com/json-iterator/go

  • Polygon: Json Database System designed to run on small servers (as low as 16MB) and still be fast and flexible.

    Json-iterator (https://github.com/json-iterator/go), you can replace all of encoding/json with this. It does the same thing but it's faster.
  • How can we umarshal a Big JSON effectively?
    4 projects | /r/golang | 16 Nov 2022
    Do you want to look at every field all at the same time? If not, you can pick out individual fields. There's other packages such as https://github.com/tidwall/gjson or https://github.com/json-iterator/go that let you pass in paths such as "a.b.c" to extract single fields.
  • Designing a config API for microservices applications built using Go
    4 projects | dev.to | 10 Nov 2022
    For each Go type used within the config, we generate a separate unmarshaller function. The unmarshallers use json-iterator to process the output from CUE, while tracking the path within the config to the unmarshalled value. This path tracking will allow the function to check if live overrides have been provided on that path and return the override instead.
  • What type of software do you write at your workplace?

    https://github.com/json-iterator/go an alternative JSON encoding package which allows to stream (flush out) encoded data as soon as it's able to (which is in contrast with the stock package which buffers everything until the encoding is known to be complete and OK).
  • Some Go(lang) tips
    4 projects | dev.to | 2 Oct 2021
    What to use Easyjson is about the top of the pack and it's straightforward. The downside of efficient tools is that they use code generation to create the code required to turn your structs into json to minimise allocations. This is a manual build step which is annoying. Interestingly json-iterator also uses reflection but it's significantly faster. I suspect black magic.

    I think you have to parse the json, if you dont know exactly what you are looking for and want some validation und prevent manual parsing errors. For parsing big json files it is recommend to read and decode it as stream. Here is an example. If you have serious performance criteria take a look at jsoniter. It can be used as 1 to 1 replacement for standard library.

    Takes like 10 minutes to write and parses very efficiently. https://github.com/json-iterator/go looks like it can provide such simple parsing
