//! # 51Degrees JavaScript builder
//!
//! The JavaScript builder element renders a client-side JavaScript include from
//! the JSON payload produced by the [`fiftyone_json_builder`] crate. The
//! generated script creates a global manager object on the client device, runs
//! any JavaScript-typed properties the JSON carries, and (when a callback URL is
//! configured) posts the evidence it gathers back to the server for a refreshed
//! result. It implements the
//! [javascript-builder specification](https://github.com/51Degrees/specifications/blob/main/pipeline-specification/pipeline-elements/javascript-builder.md).
//!
//! ## The template
//!
//! The script is rendered from a single Mustache template,
//! `JavaScriptResource.mustache`, embedded at compile time with `include_str!`.
//! Rendering uses a small,
//! pure-safe-Rust Mustache renderer (in this crate's `mustache` module) with
//! HTML escaping disabled, so the JSON payload, the callback URL and the object
//! name reach the client verbatim.
//!
//! ## Configuration and per-request overrides
//!
//! [`JavaScriptBuilderElementBuilder`] sets the host, endpoint, protocol, object
//! name, cookie behavior and minification. Several of those can be overridden
//! per request through evidence (`query.fod-js-object-name`,
//! `query.fod-js-enable-cookies`, `header.host` and `header.protocol`). See
//! [`JavaScriptBuilderElement`] for the full derivation rules.
//!
//! ## Minification
//!
//! With the default-on `minify` feature the rendered script is minified by the
//! oxc toolchain (see the `minify` module). A minification failure falls back to
//! the unminified script, so valid JavaScript is always served. The `set_minify`
//! builder flag turns minification off for an element, and building the crate
//! with `default-features = false` drops the oxc dependency entirely.
//!
//! ## A worked pipeline
//!
//! ```
//! use std::sync::Arc;
//! use fiftyone_pipeline_core::{Evidence, Pipeline};
//! use fiftyone_json_builder::JsonBuilderElement;
//! use fiftyone_javascript_builder::{JavaScriptBuilderElement, JAVASCRIPT_BUILDER_DATA_KEY};
//!
//! let pipeline = Pipeline::builder()
//!     .add_element(Arc::new(JsonBuilderElement::new()))
//!     .add_element(Arc::new(JavaScriptBuilderElement::new()))
//!     .build()
//!     .unwrap();
//!
//! let mut data = pipeline.create_flow_data_with(
//!     Evidence::builder().add("header.host", "localhost").build(),
//! );
//! data.process().unwrap();
//!
//! let js = data.get(JAVASCRIPT_BUILDER_DATA_KEY).unwrap().javascript().to_owned();
//! assert!(js.contains("fiftyoneDegreesManager"));
//! ```
