Installation

Manually

Ensure all requirements are satisfied before installing.

You can use either of these options to install freyr:

  • Install globally via NPM:

    npm install -g miraclx/freyr-js
  • Install globally via Yarn:

    yarn global add miraclx/freyr-js
  • Or alternatively, you can build from source
    git clone https://github.com/miraclx/freyr-js.git freyr-js
    cd freyr-js
    • If using npm:

      npm install
      
      # to have access to the freyr command globally
      npm link
    • If using yarn:

      yarn install
      
      # to have access to the freyr command globally
      yarn link

Docker

We provide officially prebuilt images (automated builds from this repo).

Pull the image:

docker pull freyrcli/freyrjs
Base Image Size Tag
Alpine (musl) * Docker Image Size (:alpine) freyrcli/freyrjs:latest
Arch Linux Docker Image Size (:archlinux) freyrcli/freyrjs:archlinux

*: default

Usage (Docker)

Structure
docker run -it --rm -v $PWD:/data <tag> [options, arguments and queries...]

Example, with the freyrcli/freyrjs:latest tag:

docker run -it --rm -v $PWD:/data freyrcli/freyrjs:latest

Alternatively, create a handy alias

alias freyr='docker run -it --rm -v $PWD:/data freyrcli/freyrjs:latest'

  • * Debian: sudo apt-get install python3.6
  • * Arch Linux: sudo pacman -S python
  • Android (Termux): apt install python
  • Alpine Linux: sudo apk add python3
  • (*: should already be preinstalled)

  • Windows + macOS:
    • Ensure to extract the ffmpeg binary from the compressed file, if it's in one.
    • make sure it's available in your PATH
    • otherwise, set FFMPEG_PATH to explicitly specify binary to use
  • Linux: (check individual package managers)
    • Debian: The ppa:mc3man/trusty-media PPA provides recent builds

    • or the bins/windows folder of this project directory. Create the folder(s) if they don't exist.
  • Linux + macOS (the brew package isn't recommended):
    • unzip and place the AtomicParsley in your PATH.
    • or the bins/posix folder of this project directory. Create the folder(s) if they don't exist.
  • Alternatively:
    • Debian: sudo apt-get install atomicparsley
    • Arch Linux: sudo pacman -S atomicparsley

Batch downloads

via Arguments

Queries can be collated to be processed at once.

freyr query1 query2 ... queryN
via Batch File

Queries can be batched into a file and loaded all at once with the -i, --input <FILE> flag. Queries should be on separate lines.

Lines starting with a # are treated as comments and ignored. comments can also be inlined with everything following the # character ignored.

# ./queue.txt

# Hailee Steinfeld
https://open.spotify.com/track/5Gu0PDLN4YJeW75PpBSg9p # (track) Let Me Go
https://open.spotify.com/track/7GCVboEDzfL3NKp1NrAgHR # (track) Wrong Direction

# (album) Rina Sawayama
https://open.spotify.com/album/3stadz88XVpHcXnVYMHc4J
freyr -i ./queue.txt

Use the --help flag to see full usage documentation.

URIs

Services can be queried with short URIs containing the type and ID for the resource.

identifier type id
URI Short Tags : track : ~
album
artist
playlist

Use the urify subcommand to parse betweeen URIs and its equivalent URL representation, and vice-versa. Creating freyr-compatible queue output.

freyr urify https://open.spotify.com/album/2D23kwwoy2JpZVuJwzE42B --no-header --no-logo --no-tag

Service Configuration

The conf.json file already includes some API tokens for service authentication and should work right out of the box. [See Project specific configuration]

Spotify
  • spotify: <object>
    • clientId: <string>
    • clientSecret: <string>
    • refreshToken: <string>

Spotify requires a clientId and a clientSecret that can be gotten from their developer dashboard.

If you wish to create and use custom keys, [See Spotify API Authorization].

An optional refreshToken option can be defined which can be used to authenticate a session without necessarily requesting explicit permissions. The refreshToken is already bound to a pre-authenticated account.

An invalid refreshToken, when specified, would fallback to requesting account access which in-turn would request re-authentication of the users' account.

Spotify API Authorization

  1. Sign in to the Spotify Dashboard
  2. Click CREATE A CLIENT ID and create an app
  3. Now click Edit Settings
  4. Add http://localhost:36346/callback to the Redirect URIs
  5. Include the clientId and the clientSecret from the dashboard in the spotify object that is a property of the services object of the conf.json file. [See Confiuration]
  6. You are now ready to authenticate with Spotify!
Apple Music
  • apple_music: <object>
    • storefront: <string>
    • developerToken: <string>

This library already includes a pre-defined developer token that should work at will. This developer token is the default token, extracted off the Apple Music website. While this developer token could expire over time, we'll try to update with the most recent developer token as time goes on.

To create a custom developer token, please refer to the Apple Music documentation on this topic.

The storefront option defines the default storefront to be used in the absence of a specification.

Apple Music API Authorization

[See Apple Music API: Getting Keys and Creating Tokens ]

After successfully acquiring the developer token, include the developerToken to the apple_music object that's a property of the services object in the conf.json file. [See Confiuration]

Deezer
  • deezer: <object>
    • retries: <number>

Authentication unrequired. API is freely accessible.

Because of the 50 requests / 5 seconds limit enforced on an IP-basis for Deezer's API [See #32], occasionally a Quota limit exceeded error would be thrown by the API server.

To combat this, freyr employs request batching, managed delays and finally, retries when things go awry.

You can configure how many retries you want freyr to make before accepting failure.

Return Codes

  • 0: OK
  • 1: Invalid query
  • 2: Invalid flag value
  • 3: Invalid / Inexistent configuration file
  • 4: Network error
  • 5: Error with working directory
  • 6: Failed to initialize a freyr instance
  • 7: An error occurred checking dependency paths

FilterRules

Filter rules each to be matched against the tracks involved in any operation.

Used as values to the -l, --filter flag or as key-value pairs in the filters array of the configuration file.

Development

Manually Building

Feel free to clone and use in adherance to the license. Pull requests are very much welcome.

git clone https://github.com/miraclx/freyr-js.git freyr-js
cd freyr-js
  • If using NPM:

    npm install
    
    # to have access to the freyr command globally
    npm link
  • If using Yarn:

    yarn install
    
    # to have access to the freyr command globally
    yarn link

Docker Development

To facilitate development and experimentation through Docker, Dockerfiles are provided in the docker/ folder for your convenience.

Base Image OS Average Build Network Usage Average Disk Usage File
Alpine (musl) ~ 80 MB ~ 182 MB docker/Dockerfile.alpine
Arch Linux ~ 190 MB ~ 1.2 GB docker/Dockerfile.archlinux
# building with default dockerfile (alpine)
git clone https://github.com/miraclx/freyr-js.git freyr
cd freyr
docker build -t freyr-dev:latest .

# alternatively, you can use any other dockerfile
docker build -t freyr-dev:archlinux -f docker/Dockerfile.archlinux .

Afterwards, you can drop into the container by explicitly defining the entrypoint

docker run -it --entrypoint bash freyr-dev:latest

# Alternatively, create a handy alias
alias freyrd='docker run -it --entrypoint bash freyr-dev:latest'

Optionally, you can use these interesting flags to customize the experience.

  • -h freyr-dev sets the container hostname to freyr-dev
  • -m 1G sets the container memory limit
  • -v $PWD:/data mounts the current working directory to /data within the container.
  • --cpus 2 limits the container to using 2 CPU cores

The freyr source would be available in the /freyr directory within the container along with a globally registered command freyr for calling the script.
