Deprecated This repository is replaced with a new, simpler behavior implementation found in Browsertrix Behaviors. The new implementation compiles all behaviors to a single JS file, which can be injected anywhere, removing the need for a CLI or server found in this implementation. Behaviors found here will slowly be ported over to Browsertrix Behaviors as needed.

wr-behaviors

Installation

To use this project you must first install its dependencies

$ yarn install
# or "npm install"

Build behaviors

npm run generate-runnable-behaviors
npm run build-dev

If you wish to use this project via Docker, see the Docker portion of the Usage section.

Usage

wr-behaviors provides a cli to help you use this project.

The commands available to you are displayed below

$ ./bin/cli --help

Usage: cli [options] [command]

Options:
  -V, --version  output the version number
  -h, --help     output usage information

Commands:
  api            Start the behavior api sever
  behaviors      Build and or validate behaviors, or generate their metadata
  help [cmd]     display help for [cmd]

The cli provides two commands api and behaviors and each command has its own options.

Behaviors command

To build the behaviors made available by wr-behaviors execute ./bin/cli behaviors -b.

This will build the behaviors using the behavior config file located in the root of this project.

The built behaviors, along with a behavior metadata file (behaviorMetadata.js), can be found in the dist directory which will be created for you if it does not exist in the root of this project.

The full options that available for use with this command are show below.

$ ./bin/cli behaviors --help

Usage: cli-behaviors [options]

Options:
  -V, --version                    output the version number
  -v, --validate [fileOrDir]       
  -c, --config [configPath]        Path to the behavior config file (default: "<path to wr-behaviors>/behavior-config.yml")
  -b, --build [fileOrDir]          Build a behaviors or all behaviors contained within a directory (default: true)
  -w, --watch [behaviorFileOrDir]  Watch the files, and their imports, in the build directory for re-bundling on changes (placed in dist directory)
  --metadata [dumpDir]             Generate behavior metadata, optionally supplying a path to directory where metadata is to be placed. Defaults to current working directory
  -h, --help                       output usage information

API command

To run the behavior api server execute ./bin/cli api --build-behaviors.

This will start the api server after all behaviors provided by wr-behaviors have been built.

If you have already built the behaviors using the behaviors command provided by the cli then you may omit the --build-behaviors flag.

The full options that available for use with this command are show below.

$ ./bin/cli api --help

Usage: cli-api [options]

Options:
  -V, --version                        output the version number
  -p, --port [port]                    The port the api server is to bind to (default: 3030)
  -h, --host [host]                    The host address the server is listen on (default: "127.0.0.1")
  -b, --behaviorDir [behaviorDir]      The path to the directory containing the build behaviors (default: "<path to wr-behaviors>/dist")
  -m, --behaviorMetadata [medataPath]  The path to the behavior metadata (default: "<path to wr-behaviors>/dist/behaviorMetadata.js")
  --build-behaviors                    Should the api server build the behaviors for starting up
  -h, --help                           output usage information

Some configuration of the api server can be done via the environment variables listed below

• BEHAVIOR_API_HOST: the host the api server will use (e.g. 127.0.0.1)
• BEHAVIOR_API_PORT: the port the api server will listen on (e.g. 3030)
• WR_BEHAVIOR_DIR: path to the directory containing the built behaviors
• WR_BEHAVIOR_METADATA_PATH: path to the behavior metadata file
• BUILD_BEHAVIORS: should the api server build the behaviors before starting

Docker

To build the wr-behaviors docker image (webrecorder/behaviors:latest) execute docker-compose build.

The image created is suitable for building behaviors and running the behavior api server.

The default configuration of the image is to run the api server, however you can substitute the default command with any of the cli commands listed previously.

For more information please consult the provided Dockerfile and docker-compose.yml files.
