    Simple to use local JSON database. Use native JavaScript API to query. Written in TypeScript. (supports Node, Electron and the browser)

    Project mention: go-store: Lightweight embedded database in pure Go inspired by Lowdb | | 2022-12-14

    I just finished the first stable version of go-store, a lightweight embeeded database written in pure Go. It was heavily inspired by lowdb. The motivation was that I needed something simple to store information for another project and that I wanted to try out Go's generics.

  • pino

    🌲 super fast, all natural json logger

    Project mention: Logging - correlationId - headers - how? | | 2023-01-30

    Using pino as a logger, for every request on the _server_ , a unique ID generated client side in the headers, so a log may be something like:

  • jsoneditor

    A web-based tool to view, edit, format, and validate JSON

    Project mention: Fighting an itemized bill | | 2023-02-02

    I took a quick look at that turquoise guide, seems ok if you’re able to follow it. I was going to suggest googling a JSON editor/formatter like this, you would open the file with that or paste the text and it will convert it to the tree structure that will make it a little easier to navigate. JSON is just a text file, and you can open it with notepad, but I wouldn’t recommend trying to search it that way. Better to use some kind of editor to get it into the tree structure.

  • json5

    JSON5 — JSON for Humans

    Project mention: The YAML Document from Hell | | 2023-01-12

    People often forget about the environment, and I feel like a lot of the simpler services and applications could be configured through it easily.

    For anything that requires more complex structures, JSON5 ( has been gaining traction. It's basically JSON that allows a couple of more things, including comments and unquoted keys, if you're into that.

  • InfluxDB

    Build time-series-based applications quickly and at scale.. InfluxDB is the Time Series Platform where developers build real-time applications for analytics, IoT and cloud-native services. Easy to start, it is available in the cloud or on-premises.

  • body-parser

    Node.js body parsing middleware

    Project mention: How to use celebrate with Node.js | | 2022-05-24

    body-parser is a middleware that parses the body of incoming requests, and exposes the resulting object on req.body

  • form

    jQuery Form Plugin

  • Tabulator

    Interactive Tables and Data Grids for JavaScript

    Project mention: Can you recommend a React table components with virtualization and array indices (instead of key-value pairs)? | | 2023-01-22

    We use Tabulator for a similar use case at my job, it has a virtual DOM to support thousands of rows pretty well. It's not React based, it's a vanilla JS library. There is a React wrapper here but I don't have experience with that.

  • jsondiffpatch

    Diff & patch JavaScript objects

  • JSON-to-Go

    Translates JSON into a Go type in your browser instantly (original)

    Project mention: Ad hoc JSON parsing | | 2023-01-16

    Swagger is mentioned; see also the very useful and often used .

  • json-editor

    JSON Schema Based Editor

    Project mention: Ask HN: Do you use JSON Schema? Help us shape its future stability guarantees | | 2023-01-30

    I use JSON schema to generate JSON-editing forms via json-editor:

    Then I can use the same schema in the backend to validate the data, both sent in via the form and directly with the application/json content-type. It's a pretty smooth flow, and reduces a lot of redundancy.

  • SurveyJS

    Free Open-Source JavaScript form builder library with integration for React, Angular, Vue, jQuery, and Knockout that lets you load and run multiple web forms, or build your own self-hosted form management system, retaining all sensitive data on your servers. You have total freedom of choice as to the backend, because any server + database combination is fully compatible.

    Project mention: I just released an open-source form builder built with Laravel | | 2022-12-14

    Check out surveyjs/survey-library for Angular. Not exactly like this one from the thread but they have a survey creator to generate a config for their front end lib.

  • fast-json-stringify

    2x faster than JSON.stringify()

    Project mention: typescript-json, 2x faster JSON stringify with only one line | | 2022-04-20
  • awesome-json-datasets

    Project mention: I teach high school Computer Science. What should I make sure they learn this year? | | 2022-11-10

    Here's a list of "Awesome JSON datasets":

  • serialize-javascript

    Serialize JavaScript to a superset of JSON that includes regular expressions and functions.

    Project mention: Trying and failing to implement react redux persistence | | 2022-02-19

    ​ and this is my config for the plugin: { resolve:gatsby-plugin-react-redux-persist, options: { // [required] - path to your createStore module pathToCreateStoreModule: './src/store', // [optional] - options passed toserialize-javascript // info: // will be merged with these defaults: serialize: { space: 0, // ifisJSONis set tofalse,evalis used to deserialize redux state, // otherwiseJSON.parseis used isJSON: true, unsafe: false, ignoreFunction: true, }, // [optional] - if true will clean up after itself on the client, default: cleanupOnClient: true, // [optional] - name of key onwindowwhere serialized state will be stored, default: windowKey: '__PRELOADED_STATE__', }, },

  • jsonform

    Build forms from JSON Schema. Easily template-able. Compatible with Bootstrap 3 out of the box.

  • neo

    The application worker driven frontend framework (by neomjs)

    Project mention: I scraped +650K frontend jobs for 14 months and here are the Most Demanded Javascript Frontend Frameworks in this 2022 (From October 1, 2021 to November 30, 2022) | | 2023-01-18

    I'm hoping maybe the guy behind Neo.js and the Vue team can collab to put out an even faster framework that does more with the canvas as opposed to direct dom manipulations. As far as I can tell webGPU & wasm will reshape how things are done in the frontend and it may make sense to just render everything inside of a canvas.

  • node-convict

    Featureful configuration management library for Node.js

    Project mention: What's the best practice to fetch 10 random images from Cloud Storage to display to users? | | 2022-04-08

    However, if you have plans to increase the number of images, like to 500 for example, then I'd suggest using server-side pagination here. I'd also suggest using cursor-based pagination instead of offset-based for better performance. Github uses cursor-based pagination on stargazers page since the number of stars can get potentially huge for a repo.

  • json-rules-engine

    A rules engine expressed in JSON

    Project mention: How should I test this function? Should I test all possibilities? Like hasDescription = true and hasExperience = true should return true. hasDescription = true and hasSkill = true should return false | | 2022-09-20

    If you find yourself needing to do alot of these profile matching functions I would recomend building either a mini-rules interpreter or using something like this to do the matching for you.

  • fast-xml-parser

    Validate XML, Parse XML and Build XML rapidly without C/C++ based libraries and no callback.

    Project mention: XML: read and write with Node.js | | 2022-12-10

    After experimenting with a few different XML parsers I settled on fast-xml-parser. It's fast, it's simple and it's well maintained. It also handles XML namespaces and attributes well. (This appears to be rare in XML parsers.)

  • Paste JSON as Code • quicktype

    Xcode extension to paste JSON as Swift, Objective-C, and more

    Project mention: System language influences JSON decoding | | 2023-02-02

    Seems like date handling or decimal point differences are the most likely causes. I would paste your JSON into and see if the Swift code they spit out works under other languages.
