Protocol Buffers for JavaScript

This is a minimal implementation of Google Protocol Buffers for JavaScript and TypeScript.
It generates completely self-contained code without any dependencies.
Install it using npm:

``
npm install pbjs
`

Unlike other JavaScript implementations, this library doesn't write out default values.
This makes it possible to tell if a field has been written at all or not, which allows for efficient encoding of maps.
For example, it's possible to distinguish between a missing list and a list that is present but empty.

Command-Line Examples

* Generate ES5 JavaScript:

`
pbjs wire-format.proto --es5 wire-format.js
`

See test.proto.es5.js for an example of the generated code.

* Generate ES6 JavaScript:

`
pbjs wire-format.proto --es6 wire-format.js
`

See test.proto.es6.js for an example of the generated code.

* Generate TypeScript:

`
pbjs wire-format.proto --ts wire-format.ts
`

See test.proto.ts for an example of the generated code.

* Convert to JSON:

`
pbjs wire-format.proto --decode MessageType < wire-format.bin > wire-format.json
`

* Convert to Binary:

`
pbjs wire-format.proto --encode MessageType < wire-format.json > wire-format.bin
`

API Example

`js
const pbjs = require('pbjs');

const schema = pbjs.parseSchema(
message Demo {
optional int32 x = 1;
optional float y = 2;
}
).compile();

const buffer = schema.encodeDemo({x: 1, y: 2});
console.log(buffer);

const message = schema.decodeDemo(buffer);
console.log(message);
`

Running the above code should output this:

`

{ x: 1, y: 2 }
