CommonJS-style imports (eg. `var protos = require('my-protos');`) +2. Closure-style imports (eg. `goog.require('my.package.MyProto');`) + +Support for ES6-style imports is not implemented yet. Browsers can +be supported by using Browserify, webpack, Closure Compiler, etc. to +resolve imports at compile time. + +To use Protocol Buffers with JavaScript, you need two main components: + +1. The protobuf runtime library. You can install this with + `npm install google-protobuf`, or use the files in this directory. +2. The Protocol Compiler `protoc`. This translates `.proto` files + into `.js` files. The compiler is not currently available via + npm, but you can download a pre-built binary + [on GitHub](https://github.com/google/protobuf/releases) + (look for the `protoc-*.zip` files under **Downloads**). + + +Setup +===== + +First, obtain the Protocol Compiler. The easiest way is to download +a pre-built binary from [https://github.com/google/protobuf/releases](https://github.com/google/protobuf/releases). + +If you want, you can compile `protoc` from source instead. To do this +follow the instructions in [the top-level +README](https://github.com/google/protobuf/blob/master/src/README.md). + +Once you have `protoc` compiled, you can run the tests by typing: + + $ cd js + $ npm install + $ npm test + + # If your protoc is somewhere else than ../src/protoc, instead do this. + # But make sure your protoc is the same version as this (or compatible)! + $ PROTOC=/usr/local/bin/protoc npm test + +This will run two separate copies of the tests: one that uses +Closure Compiler style imports and one that uses CommonJS imports. +You can see all the CommonJS files in `commonjs_out/`. +If all of these tests pass, you know you have a working setup. + + +Using Protocol Buffers in your own project +========================================== + +To use Protocol Buffers in your own project, you need to integrate +the Protocol Compiler into your build system. The details are a +little different depending on whether you are using Closure imports +or CommonJS imports: + +Closure Imports +--------------- + +If you want to use Closure imports, your build should run a command +like this: + + $ protoc --js_out=library=myproto_libs,binary:. messages.proto base.proto + +For Closure imports, `protoc` will generate a single output file +(`myproto_libs.js` in this example). The generated file will `goog.provide()` +all of the types defined in your .proto files. For example, for the unit +tests the generated files contain many `goog.provide` statements like: + + goog.provide('proto.google.protobuf.DescriptorProto'); + goog.provide('proto.google.protobuf.DescriptorProto.ExtensionRange'); + goog.provide('proto.google.protobuf.DescriptorProto.ReservedRange'); + goog.provide('proto.google.protobuf.EnumDescriptorProto'); + goog.provide('proto.google.protobuf.EnumOptions'); + +The generated code will also `goog.require()` many types in the core library, +and they will require many types in the Google Closure library. So make sure +that your `goog.provide()` / `goog.require()` setup can find all of your +generated code, the core library `.js` files in this directory, and the +Google Closure library itself. + +Once you've done this, you should be able to import your types with +statements like: + + goog.require('proto.my.package.MyMessage'); + + var message = proto.my.package.MyMessage(); + +CommonJS imports +---------------- + +If you want to use CommonJS imports, your build should run a command +like this: + + $ protoc --js_out=import_style=commonjs,binary:. messages.proto base.proto + +For CommonJS imports, `protoc` will spit out one file per input file +(so `messages_pb.js` and `base_pb.js` in this example). The generated +code will depend on the core runtime, which should be in a file called +`google-protobuf.js`. If you are installing from `npm`, this file should +already be built and available. If you are running from GitHub, you need +to build it first by running: + + $ gulp dist + +Once you've done this, you should be able to import your types with +statements like: + + var messages = require('./messages_pb'); + + var message = new messages.MyMessage(); + +The `--js_out` flag +------------------- + +The syntax of the `--js_out` flag is: + + --js_out=[OPTIONS:]output_dir + +Where `OPTIONS` are separated by commas. Options are either `opt=val` or +just `opt` (for options that don't take a value). The available options +are specified and documented in the `GeneratorOptions` struct in +[src/google/protobuf/compiler/js/js_generator.h](https://github.com/google/protobuf/blob/master/src/google/protobuf/compiler/js/js_generator.h#L53). + +Some examples: + +- `--js_out=library=myprotos_lib.js,binary:.`: this contains the options + `library=myprotos.lib.js` and `binary` and outputs to the current directory. + The `import_style` option is left to the default, which is `closure`. +- `--js_out=import_style=commonjs,binary:protos`: this contains the options + `import_style=commonjs` and `binary` and outputs to the directory `protos`. + +API +=== + +The API is not well-documented yet. Here is a quick example to give you an +idea of how the library generally works: + + var message = new MyMessage(); + + message.setName("John Doe"); + message.setAge(25); + message.setPhoneNumbers(["800-555-1212", "800-555-0000"]); + + // Serializes to a UInt8Array. + bytes = message.serializeBinary(); + + var message2 = new MyMessage(); + message2.deserializeBinary(bytes); + +For more examples, see the tests. You can also look at the generated code +to see what methods are defined for your generated messages. diff --git a/ui/scripts/node_modules/google-protobuf/google-protobuf.js b/ui/scripts/node_modules/google-protobuf/google-protobuf.js new file mode 100644 index 00000000000..1c9a810f389 --- /dev/null +++ b/ui/scripts/node_modules/google-protobuf/google-protobuf.js @@ -0,0 +1,319 @@ +var COMPILED=!0,goog=goog||{};goog.global=this;goog.isDef=function(a){return void 0!==a};goog.exportPath_=function(a,b,c){a=a.split(".");c=c||goog.global;a[0]in c||!c.execScript||c.execScript("var "+a[0]);for(var d;a.length&&(d=a.shift());)!a.length&&goog.isDef(b)?c[d]=b:c=c[d]?c[d]:c[d]={}};
