Webpack loader to translate protobuf definitions to ProtoBuf.js modules. Equivalent to running your definitions through the pbjs CLI.
This allows you to use the light or minimal ProtoBuf.js distributions without an explicit compile step in your build pipeline.
npm install --save-dev protobufjs-loader// webpack.config.js
module.exports = {
// ...
module: {
rules: [{
test: /\.proto$/,
use: {
loader: 'protobufjs-loader',
options: {
/* Import paths provided to pbjs.
*
* default: webpack import paths (i.e. config.resolve.modules)
*/
paths: ['/path/to/definitions'],
/* Additional command line arguments passed to pbjs.
*
* default: []
*/
pbjsArgs: ['--no-encode'],
/* Enable Typescript declaration file generation via pbts.
*
* Declaration files will be written every time the loader runs.
* They'll be saved in the same directory as the protobuf file
* being processed, with a `.d.ts` extension.
*
* This only works if you're using the 'static-module' target
* for pbjs (i.e. the default target).
*
* The value here can be a config object or a boolean; set it to
* true to enable pbts with default configuration.
*
* default: false

* const jsonDescriptor = require('json!my/compiled/protobuf.js');
