npm install it-concat
Concat buffers to a single BufferList
:
const concat = require('it-concat')
const fs = require('fs')
fs.writeFileSync('./test.txt', 'Hello World!')
// Node.js Readable Streams are async iterables!
const chunks = await concat(fs.createReadStream('./test.txt'))
// chunks is a BufferList
console.log(chunks)
/*
BufferList {
_bufs: [ <Buffer 48 65 6c 6c 6f 20 57 6f 72 6c 64 21> ],
length: 12
}
*/
console.log(chunks.toString())
// Hello World!
Concat buffers to a single string:
const concat = require('it-concat')
const fs = require('fs')
fs.writeFileSync('./test.txt', 'Hello World!')
// Node.js Readable Streams are async iterables!
// Note that we pass `{ type: 'string' }` to tell concat that we want a string
// back and not a buffer. This is necessary because the source data is buffer(s).
const chunks = await concat(fs.createReadStream('./test.txt'), { type: 'string' })
console.log(chunks)
// Hello World!
Concat strings to a single string:
const concat = require('it-concat')
const fs = require('fs')
fs.writeFileSync('./test.txt', 'Hello World!')
// Node.js Readable Streams are async iterables!
// Note that we don't need to pass `{ type: 'string' }` to tell concat that we
// want a string back because the source data is buffer(s).
const chunks = await concat(fs.createReadStream('./test.txt', { encoding: 'utf8' }))
console.log(chunks)
// Hello World!
const concat = require('it-concat')
concat(source, options?): Promise
Concat all buffers or strings yielded from the async iterable source
into a single BufferList
or string
.
source
(AsyncIterable<Buffer | BufferList | string>
) - the source iterable to concat fromoptions
(Object
) - optional optionsoptions.type
(string
) - return type of the function, pass 'string'
to recieve a string or 'buffer'
for a BufferList
.Returns a Promise
that resolves to a BufferList
or string
.
If options.type
is not passed the type of the objects yielded from the source
is detected and a BufferList
or string
is returned appropriately. If the source
does not yield anything an empty BufferList
is returned. If the source is expected to return strings (but may not yield anything), pass options.type: 'string'
to ensure an empty string is returned instead of an empty BufferList
.
