Versioning

We follow Semantic Versioning for all packages in the Smart Invoice monorepo. To keep versions synchronized across packages, we use syncpack. After making changes and updating versions in package.json, you can ensure consistency by running:

pnpx syncpack fix-mismatches

This command checks for version mismatches and updates them across the monorepo to maintain alignment.

Metadata Schema Standard

All metadata uploaded to IPFS and saved as details in a Smart Invoice contract must adhere to the following schema:

{
  projectName: "Project Name",
  projectDescription: "Description of the project",
  projectAgreement: [{
    type: "https", // or "ipfs"
    src: "https://urlToAgreement.com",
    createdAt: "seconds since epoch"
  }],
  startDate: UNIX_TIMESTAMP,
  endDate: UNIX_TIMESTAMP
}

• projectName: The name of the project.
• projectDescription: A brief description of the project.
• projectAgreement: An array of agreements related to the project, each with a type and src that must match exactly.
• startDate: The project start date, represented as a UNIX timestamp.
• endDate: The project end date, represented as a UNIX timestamp.
