Plumbing
Prismatic's Clojure(Script) utility belt
Plumbing is a general-purpose Clojure utility belt and data transformation library endorsed for its pragmatic approach to everyday tasks. It offers a toolkit of macros and functions that simplify common data manipulation patterns, and includes a “Graph” abstraction for structured computation flows. Most of it is also compatible with ClojureScript. Graph is a simple and declarative way to specify a structured computation, which is easy to analyze, change, compose, and monitor. ... -

RxGo
Reactive Extensions for the Go language
...It is about processing streams of events or items, with events being any occurrences or changes within the system. A stream of events is called an Observable. An operator is a function that defines an Observable, how and when it should emit data. The RxGo implementation is based on the concept of pipelines. A pipeline is a series of stages connected by channels, where each stage is a group of goroutines running the same function. Each operator is a transformation stage. By default, everything is sequential. Yet, we can leverage modern CPU architectures by defining multiple instances of the same operator. ... -

Json Node Tree Library
Represents JSON doc as a nodes tree for transforms like XPATH & XSLT.
Json Node Tree framework is provisioning of transformation operations for JSON documents similar XML XPATH and XSLT. The framework parses textual JSON document to nodes tree that represents JSON entity: object, array or value of primitive type. Generated tree allows to modify values of nodes and/or structure of the given JSON document. Representation of JSON object as a nodes tree allows implement an operations such as path query and transformations (like XPATH and XSLT for XML). -

Muze
Composable data visualisation library for web
Muze is a composable data visualization library for the web that enables developers to create highly interactive and exploratory charts using a data-first design philosophy. Built around a layered Grammar of Graphics approach, it allows users to define visualizations declaratively by mapping data attributes to visual components such as axes, colors, and shapes. The library emphasizes composability, meaning multiple layers and interactions can be combined to produce complex, multi-dimensional... -

Enlive
Selector-based templating and transformation system for Clojure
Enlive is a Clojure library for HTML templating, transformation, and scraping, supporting composable manipulation of HTML/XML in a functional style. It allows selecting, transforming, and generating HTML fragments using CSS selectors, and supports server-side template composition, dynamic pages, and content rewriting. By default selector-transformation pairs are run sequentially. When you know that several transformations are independent, you can now specify (as an optimization) to process... -

Highland
High-level streams library for Node.js and the browser
Highland is a JavaScript library designed to simplify working with streams and asynchronous data flows by providing a functional programming interface on top of Node.js streams. It allows developers to process data in a declarative and composable way, treating streams as sequences that can be transformed using familiar functional patterns such as map, filter, reduce, and flatMap. The library abstracts away much of the complexity of handling backpressure and asynchronous callbacks, enabling developers to focus on data transformation logic rather than low-level stream management. ... -

Django REST Pandas
Serves up Pandas dataframes via the Django REST Framework
Django REST Pandas (DRP) provides a simple way to generate and serve pandas DataFrames via the Django REST Framework. The resulting API can serve up CSV (and a number of other formats for consumption by a client-side visualization tool like d3.js. The design philosophy of DRP enforces a strict separation between data and presentation. This keeps the implementation simple, but also has the nice side effect of making it trivial to provide the source data for your visualizations. This... -

Korma
Tasty SQL for Clojure
Korma is a DSL for Clojure that wraps SQL via expressive, composable Clojure constructs. It allows developers to build powerful and reusable database queries using rich abstractions instead of raw SQL strings. The most recent stable release is Korma 0.4.3, as noted above. The current edge release is Korma 0.5.0-RC1 (released Feb 28, 2018). It is not guaranteed to be bug free, and we'd welcome help from the community in identifying any bugs or regressions. The plan is to either release a... -

Queryparser
Parsing and analysis of Vertica, Hive, and Presto SQL
Queryparser is Uber’s open source Haskell library for parsing and analyzing SQL queries written in different dialects (Vertica, Hive, Presto). It creates a unified AST and supports name resolution using catalog metadata, enabling large-scale query analysis for lineage detection, analytics, and tooling. The parsing logic produces an AST with table and column identifiers that are "raw" or optionally qualified. Frequently, it is desirable to convert the AST over raw names to an AST over... -

AXEL Web Framework
Seriously good at building web sites
The AXEL framework extends XML and HTML, adding "xml actions" that perform tasks during page processing. Goto http://xmlactions.org for a full description of how it works. Actions can be as simple as inserting a page, to as complex as building query results from external data sources. The Axel Framework project consists of different components: * axel-actions (core framework) * axel-mapping (a mapping tool built on axel-actions) * axel-pager (a web page builder built on... -
