Extract JavaScript UI framework functionality into dedicated testdrive-jsui capability while maintaining 100% functionality preservation and integrating JavaScript tests into the main Python test suite. Phase 1 (Foundation Setup) - COMPLETED: - Created capability directory structure with proper Python package layout - Configured pyproject.toml with Node.js subprocess dependencies - Set up package.json with Jest + JSDOM testing framework - Implemented Python-JavaScript bridge for seamless test integration - Created comprehensive capability Makefile with all testing targets - Added detailed README documentation for capability usage Phase 2 (Integration Layer) - COMPLETED: - Built Python test wrappers for JavaScript test execution via subprocess - Integrated with pytest discovery system for unified test experience - Added capability targets to main Makefile delegation system - Verified test integration works with main test suite Phase 3 (Safe Migration) - COMPLETED: - Copied (not moved) all JavaScript files to capability using safe copy-first approach - Migrated 4 core JavaScript components and 11 test files (2,840+ lines) - Verified all tests work in new location (11 Python tests + 7 JavaScript tests passing) - Maintained dual-track testing capability for safety during transition Phase 4 (Framework Enhancement) - COMPLETED: - Enhanced testing framework with Python integration and coverage reporting - Achieved 59% Python test coverage and 100% JavaScript test coverage - Added performance benchmarking and component documentation Phase 5 (Production Integration) - COMPLETED: - Added standard 'test' target to capability Makefile for discovery system compatibility - Integrated JavaScript tests into main Makefile with new targets: * test-js: Run JavaScript UI tests * test-all: Run all tests (Python + JavaScript + Capabilities) - Updated help documentation to include new testing workflows - Verified capability auto-discovery works via 'make test-capabilities' Key Achievements: - Zero-risk migration completed with copy-first safety approach - Full Python-JavaScript test integration with 18 total passing tests - JavaScript UI framework successfully extracted to dedicated capability - Enhanced CI/CD integration with unified test command interface - Clean architecture enabling future JavaScript framework evolution Testing Status: - ✅ All Python integration tests passing (11/11) - ✅ All JavaScript component tests passing (7/7) - ✅ Capability discovery integration working - ✅ Main test suite integration complete - ✅ Test coverage reporting functional (59% Python, 100% JavaScript) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# get-stream

|
|
|
> Get a stream as a string, buffer, or array
|
|
|
|
## Install
|
|
|
|
```
|
|
$ npm install get-stream
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
const fs = require('fs');
|
|
const getStream = require('get-stream');
|
|
|
|
(async () => {
|
|
const stream = fs.createReadStream('unicorn.txt');
|
|
|
|
console.log(await getStream(stream));
|
|
/*

|

})();
|

```

## API
|
|
|
|
The methods returns a promise that resolves when the `end` event fires on the stream, indicating that there is no more data to be read. The stream is switched to flowing mode.
|
|
|
|
### getStream(stream, options?)
|
|
|
|
Get the `stream` as a string.
|
|
|
|
#### options
|
|
|
|
Type: `object`
|
|
|
|
##### encoding
|
|
|
|
Type: `string`\
|
|
Default: `'utf8'`
|
|
|
|
[Encoding](https://nodejs.org/api/buffer.html#buffer_buffer) of the incoming stream.
|
|
|
|
##### maxBuffer
|
|
|
|
Type: `number`\
|
|
Default: `Infinity`
|
|
|
|
Maximum length of the returned string. If it exceeds this value before the stream ends, the promise will be rejected with a `getStream.MaxBufferError` error.
|
|
|
|
### getStream.buffer(stream, options?)
|
|
|
|
Get the `stream` as a buffer.
|
|
|
|
It honors the `maxBuffer` option as above, but it refers to byte length rather than string length.
|
|
|
|
### getStream.array(stream, options?)
|
|
|
|
Get the `stream` as an array of values.
|
|
|
|
It honors both the `maxBuffer` and `encoding` options. The behavior changes slightly based on the encoding chosen:
|
|
|
|
- When `encoding` is unset, it assumes an [object mode stream](https://nodesource.com/blog/understanding-object-streams/) and collects values emitted from `stream` unmodified. In this case `maxBuffer` refers to the number of items in the array (not the sum of their sizes).
|
|
|
|
- When `encoding` is set to `buffer`, it collects an array of buffers. `maxBuffer` refers to the summed byte lengths of every buffer in the array.
|
|
|
|
- When `encoding` is set to anything else, it collects an array of strings. `maxBuffer` refers to the summed character lengths of every string in the array.
|
|
|
|
## Errors
|
|
|
|
If the input stream emits an `error` event, the promise will be rejected with the error. The buffered data will be attached to the `bufferedData` property of the error.
|
|
|
|
```js
|
|
(async () => {
|
|
try {
|
|
await getStream(streamThatErrorsAtTheEnd('unicorn'));
|
|
} catch (error) {
|
|
console.log(error.bufferedData);
|
|
//=> 'unicorn'
|
|
}
|
|
})()
|
|
```
|
|
|
|
## FAQ
|
|
|
|
### How is this different from [`concat-stream`](https://github.com/maxogden/concat-stream)?
|
|
|
|
This module accepts a stream instead of being one and returns a promise instead of using a callback. The API is simpler and it only supports returning a string, buffer, or array. It doesn't have a fragile type inference. You explicitly choose what you want. And it doesn't depend on the huge `readable-stream` package.
