README
hook-std
Hook and modify stdout and stderr
Install
$ npm install hook-std
Usage
const assert = require('assert');
const hookStd = require('hook-std');
(async () => {
const promise = hookStd.stdout(output => {
promise.unhook();
assert.strictEqual(output.trim(), 'unicorn');
});
console.log('unicorn');
await promise;
})();
You can also unhook using the second transform
method parameter:
(async () => {
const promise = hookStd.stdout((output, unhook) => {
unhook();
assert.strictEqual(output.trim(), 'unicorn');
});
console.log('unicorn');
await promise;
})();
API
hookStd([options], transform)
Hook streams in streams option, by default stdout and stderr.
Returns a Promise
with a unhook()
method which, when called, unhooks both stdout and stderr and resolves the Promise
with an empty result.
hookStd.stdout([options], transform)
Hook stdout.
Returns a Promise
with a unhook()
method which, when called, resolves the Promise
with an empty result.
hookStd.stderr([options], transform)
Hook stderr.
Returns a Promise
with a unhook()
method which, when called, resolves the Promise
with an empty result.
options
Type: Object
silent
Type: boolean
Default: true
Suppress stdout/stderr output.
once
Type: boolean
Default: false
Automatically unhooks after the first call.
streams
Type: stream.Writable[]
Default: [process.stdout, process.stderr]
Writable streams to hook. This can be useful for libraries allowing users to configure a Writable Stream to write to.
transform
Type: Function
Receives stdout/stderr as the first argument and the unhook method as the second argument. Return a string to modify it. Optionally, when in silent mode, you may return a boolean
to influence the return value of .write(...)
