dcs-catalyst-client v12.0.1-168926-2

Decentraland Catalyst Client

Welcome to the Catalyst Client library. This client can be used to interact with Decentraland's Catalyst servers. You can both fetch data, or deploy new entities to the server you specify.

Installation

npm install dcl-catalyst-client

Usage

You can check the entire API here.

This library depends on two other Decentraland libraries:

• Decentraland Crypto
• Catalyst Commons

Deploying

One of the most important aspects, is the ability to deploy new entities. Here is an example of how to do it:

import { CatalystClient, DeploymentBuilder } from 'dcl-catalyst-client'
import { EntityType } from 'dcs-schemas'
import { Authenticator } from '@dcl/crypto'


// This is up to you. You will need to figure out how to make the owner of the pointer sign the entity id
const { signature, address } = await sign(entityId)

// You can then create a simple auth chain like this, or a more complex one.
const authChain = Authenticator.createSimpleAuthChain(entityId, address, signature)

// Build the client
const catalyst = await CatalystClient.connectedToCatalystIn('mainnet')
// Note: this operation is expensive, so try to store the created catalyst client somewhere, instead of re-building for each every request

// Build entity and group all files
const { entityId, files } = await catalyst.buildEntity({type: EntityType.*, pointers, files: contentFiles, metadata })

// Build the deploy data
const deployData = { entityId, files, authChain }

// Deploy the actual entity
await catalyst.deployEntity(deployData)

Releases

Stable Releases

To publish a new release, a tag following SemVer must be done in master branch following the format: MAJOR.MINOR.PATCH and that will trigger a Github Workflow that publishes the new version of the library, tagging it as latest.

Master Releases

Every commit to master branch triggers a NPM Publish with the beta version following the convention NEXT_MAJOR.NEXT_MINOR.NEXT_PATCH-TIMESTAMP.commit-COMMIT_SHA, tagging it as next.

Tag Releases

If you need to publish a NPM package in a work in progress commit, then you can create a git tag, and that will trigger an automatically NPM publish following the convention NEXT_MAJOR.NEXT_MINOR.NEXT_PATCH-TIMESTAMP.commit-COMMIT_SHA and tagging it on NPM with your custom tag: tag-CUSTOM_TAG.
