Tauri Update Server

A minimalistic implementation of a server to integrate auto-updating functionality on tauri applications.
It is meant to support user licences and channels to constrain and track the available updates.

This is a prototype.
Functionality is not fully there yet, but as of now it should be working.
No interface to update the db from here, just for content delivery.

Usage

yarn add @taus-services/taus to install the node server, or npm install @taus-services/taus. You can reference this other repository to have a working example.

Custom headers

In addition to the general structure provided by tauri update, there are three more fields which are used to define proper conditions for delivery:

• licence is a unique identifier for the user requesting the update. Internal checks can be performed to prevent download of content to suspect licences shared against terms&conditions.
• channel is used to specify the channel from which the update must be served. For example beta, stable, trial etc.
• suggested is the target version which I would like to be served. The server itself does not have to fulfill such request.

Both licence and channel, if not populated, can be automatically assigned to a default value specified as part of the server configuration.

Configuration

The behaviour of the server can be changed via a configuration object.

• port: the port to
• db: the configuration object for Sequelize.
• default_channel: the default value for channel if client is not specifying a custom header for it.
• default_secret: same for the licence.
• fastify: an object for the fastify configuration (https etc.)
• storage: base and protocol for the storage entry point. Base must be a single directory token.
• update: same but for the update entry point on the server. A default configuration is used in case no custom one has been provided. 1st level children are interpolated:

const default_config = {
    host: 'localhost',
    port: 8000,
    db: {
        dialect: 'sqlite',
        storage: './example/db'
    },
    default_channel: 'free',
    default_secret: 'free-licence',
    fastify: {},
    storage: {
        protocol:"http",
        base:"/s/"
    },
    update: {
        protocol: "http",
        base:"/u/"
    }
}

If you need you can also specify custom DB schema generated with sequelize-auto as dbSchema, but keep in mind that the codebase for the server might need to be changed from you as well.

TODO

• Accept suggestions from the client for a specific version.
• ~~Provide CLI via a separate tool to push new releases on the server.~~ via an external tool TAUS-CLI
• Custom callbacks for some of the failure events.
• ~~Async checks on the db to tag licences which are cheating.~~ via external tools
