cbor-cli

A command-line interface for encoding and parse data in the Concise Binary Object Representation (CBOR) data format (RFC8949).

Supported Node.js versions

This project now only supports versions of Node that the Node team is currently supporting. Ava's support statement is what we will be using as well. Currently, that means Node 10+ is required. If you need to support an older version of Node (back to version 6), use cbor version 5.2.x, which will get nothing but security updates from here on out.

Installation:

$ npm install -g cbor-cli

Documentation:

There is a full API that this library depends on.

For all of these tools, if a hex string is not specified, or if the file name provided is -, they will read from stdin and write to stdout.

From the command line:

cbor

$ cbor.js -h
Usage: cbor [options]

Options:
  -V, --version      output the version number
  -c, --color        Force color output even if stdout is not a TTY
  -t, --type <type>  Output type (one of: javascript, diagnose, comment) (default: "javascript")
  -h, --help         display help for command

Starts a Read, Edit, Print Loop (REPL), with the cbor package and all of its symbols already available. Almost everything you do in the REPL will also output the CBOR encoding of the result in hex, after the normal result.

cbor2comment

$ cbor2comment -h
Usage: cbor2comment [options] <file ...>

Options:
  -V, --version           output the version number
  -x, --hex <string>      Hex string input
  -t, --tabsize [spaces]  Indent amount
  -h, --help              display help for command

Convert the given file or hex string into the CBOR comment format. This is useful for understanding what each byte means.

cbor2diag

$ cbor2diag -h
Usage: cbor2diag [options] <file ...>

Options:
  -V, --version       output the version number
  -x, --hex <STRING>  Hex string input
  -h, --help          display help for command

Convert the given file or hex string into the CBOR diagnostic format. This is useful for getting a slightly more nuanced view into what CBOR came in on the wire than you would if you turned it all the way into javascript.

cbor2js

$ cbor2js -h
Usage: cbor2js [options] <file ...>

Options:
  -V, --version       output the version number
  -x, --hex <STRING>  Hex string input
  -H, --hidden        Include non-enumerable symbols and properties
  -h, --help          display help for command

Convert the given file or hex string into javascript objects, then use util.inspect to format them for consumption. This usually gives a much better idea of type information, and is easier to read than JSON.

cbor2json

$ cbor2json -h
Usage: cbor2json [options] <file ...>

Options:
  -V, --version       output the version number
  -x, --hex <STRING>  Hex string input
  -h, --help          display help for command

Convert the given file or hex string into JSON. This loses type information, but does the best it can if you want interoperability with existing JSON tooling. For example, JSON can't express Dates, so they are output as ISO 8601 strings.

js2cbor

$ js2cbor -h
Usage: js2cbor [options] <file ...>

Options:
  -V, --version    output the version number
  -x, --hex        Hex string output
  -c, --canonical  Canonical output
  -h, --help       display help for command

Read the input files or stdin as if it were a commonjs package

json2cbor

$ json2cbor -h
Usage: json2cbor [options] <file ...>

Options:
  -V, --version    output the version number
  -x, --hex        Hex string output
  -c, --canonical  Canonical output
  -h, --help       display help for command

Converts the given JSON or JSON Text Sequence file into binary CBOR. If -x is given, instead outputs a hex-encoded version of the CBOR.
