Tenzir Node v5.3.0

This release brings forth improvements to HTTP support in Tenzir, supporting requests as transformations and paginating APIs.

🚀 Features

Implement from_http client

Jun 2, 2025 · @raxyte · #5177

The from_http operator now supports HTTP client functionality. This allows sending HTTP/1.1 requests, including support for custom methods, headers, payloads, pagination, retries, and connection timeouts. The operator can be used to fetch data from HTTP APIs and ingest it directly into pipelines.

Make a simple GET request auto-selecting the parser:

from_http "https://api.example.com/data"

Post data to some API:

from_http "https://api.example.com/submit", payload={foo: "bar"}.print_json(),
          headers={"Content-Type": "application/json"}

Paginating APIs:

from_http "https://api.example.com/items",
          paginate=(x => x.next_url if x.has_more? == true)

Introduce lambda functions

May 29, 2025 · @dominiklohmann · #5150

TQL now supports lambda expressions. They are supported in the where and map functions on list, and on the newly added count_if aggregation function. Instead of [1, 2, 3].map(x, x + 1), use [1, 2, 3].map(x => x + 1). This subtle change makes it obvious that the expression is not evaluated on the entire list, but rather on each element individually.

The count_if aggregation function counts the number of elements in a list that satisfy a given predicate. For example, [1, 2, 3].count_if(x => x > 1) returns 2.

Implement http operator

May 23, 2025 · @raxyte · #5188

We implemented the http operator that allows making HTTP/1.1 requests to a URL. The operator also allows paginate APIs based on the responses.
