Utilize any compression algorithm with just a single module... The compression methods that are taken care of as of now are gzip, deflate and brotli.. if any new cool methods become mainstream, we will do our best to include them...
Any version below 1.3 works using the iltorb npm module which is ideal for any node version below 11... Versions 1.3 and above use node's native zlib brotli methods and are ideal with Node.js version 11 (and above)... There is a thrown error when you attempt to use the latest version but aren't in an ideal environment to do such...
Like we need to tell you but run this...
npm install pulverized
And then you can start using the module by doing the below...
var Pulverized = require('pulverized');
Lastly, you can understand the methods and signatures of those methods if you read the below section...
This is the Pulverized singleton 'illustrated' as a tree...
Pulverized
|-- compress
| |-- async
| | |-- br ( dataToCompress, callback, brotliSettingsObject )
| | |-- df ( dataToCompress, callback, deflateSettingsObject )
| | \-- gz ( dataToCompress, callback, gzipSettingsObject )
| |
| |-- stream
| | |-- br ( brotliSettingsObject )
| | |-- df ( deflateSettingsObject )
| | \-- gz ( gzipSettingsObject )
| |
| \-- sync
| |-- br ( dataToCompress, brotliSettingsObject )
| |-- df ( dataToCompress, deflateSettingsObject )
| \-- gz ( dataToCompress, gzipSettingsObject )
|
\-- decompress
|-- async
| |-- br ( dataToDecompress, callback )
| |-- df ( dataToDecompress, callback )
| \-- gz ( dataToDecompress, callback )
|
|-- stream
| |-- br ( )
| |-- df ( )
| \-- gz ( )
|
\-- sync
|-- br ( dataToDecompress )
|-- df ( dataToDecompress )
\-- gz ( dataToDecompress )
Within all compression methods, the pulverizedSettingsObject
uses the encoding parameters of the relevant algorithm deflate, gzip or brotli within the object.
The below pretty much points out what is in the examples
folder... so I have each example from below in those files and more...
Pulverized["COMPRESS OR DECOMPRESS"]["ALGORITHM"].sync(
buffer /* required */,
pulverizedSettingsObject /* optional */
)
fs.writeFileSync(
"./examples/lorem-sync-l9.txt.gz",
Pulverized.compress.gz.sync(
fs.readFileSync(loremFilename,"utf8"), {
level:9
}
)
);
Pulverized["COMPRESS OR DECOMPRESS"]["ALGORITHM"].async(
buffer /* required */,
callback /* required */,
pulverizedSettingsObject /* optional */
)
Pulverized.compress.df.async(
fs.readFileSync(loremFilename,"utf8"),
function(err, output){
fs.writeFileSync(
"./examples/lorem-async-l5.txt.df",
output
);
console.log(
"df decompressed async setup",
Pulverized.decompress.df.async(
fs.readFileSync(
"./examples/lorem-async-l5.txt.df"
), function(err, output){
console.log(
"df decompressed output",
err,
output
)
}
)
);
},{
level:5
}
)
Pulverized["COMPRESS OR DECOMPRESS"]["ALGORITHM"].stream(
pulverizedSettingsObject /* optional */
)
fs.createReadStream(loremFilename)
.pipe(Pulverized.compress.br.stream({
quality:1
}))
.pipe(fs.createWriteStream("./examples/lorem-stream-q1.txt.br"));
