A tool belt for concise schemas.

Why? ✨

  • Write your schema once, concisely (using e.g. YAML or JSON)
  • If it's too large, divide it into manageable chunks
  • Use plugins to import it into Concise and then export it again in whatever format you need:
    • YAML (concise-yaml)
    • JSON (concise-json)
    • PostgreSQL SQL (concise-pg)
    • Sequelize ORM (concise-sequelize)
    • Flow types (concise-flow)
    • GraphQL schema language (concise-graphql)
    • Entity-relationship diagram (concise-diagram)
    • Firebase database rules (concise-firebase)
  • Update your schema in one place!

Installation

You will need to install concise and the input/output plugins you need. For example:

$ npm install concise concise-yaml concise-pg

Usage

Concise input/output

Concise schema reference

Here is an example schema written in YAML:

models:
  common:
    isIncludeOnly: true
    fields:
      id:
        type: uuid
        isPrimaryKey: true
      notes:
        type: string
        isLong: true

  person:
    description: A project member
    includes: { common: true }
    fields:
      name:
        description: Name of the user
        type: string
        validations:
          isRequired: true
          isUnique: true
      surname: { type: string }
      aBoolean:
        type: boolean
        validations:
          isRequired: true
        defaultValue: false
    relations:
      project: true

  project:
    includes: { common: true }
    fields:
      name: { type: string }
    relations:
      projectManager:
        model: user
        validations:
          isRequired: true
      technicalManager:
        model: user
        inverse: false

This simple schema already illustrates some of concise's features:

  • Includes: common fields (and relations) can be extracted from models. Models marked as isIncludeOnly may have special treatment in some plugins, e.g. concise-pg will not generate tables for them, concise-diagram will omit them in diagrams, etc.

  • Comments: description attributes can be set on models, fields and relations. They are strongly recommended and are taken into account in all built-in plugins: concise-graphql includes them in schema (so they can be shown in the great GraphiQL tool), concise-diagram shows them as tooltips in diagrams, concise-pg generates COMMENT SQL statements for them, etc.

  • Relations are defined at the model that contains the foreign key (e.g. in a 1:N relation, at the 1 end). In the example above, a person belongs to a project.

  • Bidirectional relations: relations are bidirectional by default, and the inverse relation (in the previous example, from project to person) is plural by default. The inverse relation can be fully customised and even removed (set to false).

  • Validation rules can be applied to both model fields and relations.

Plugin options

Common options

Input options:

  • file? (string): if specified, raw input schema will be read from the specified path

  • Note: either file or raw should be specified for input processors

concise-yaml

Input/output.

No specific options.

concise-json

Input/output.

Output options:

  • prettyJson? (boolean = false): prettify JSON output

concise-pg

Output-only.

Output options:

  • file? (string): if specified, output will be written to the specified path
  • schema? (string): PostgreSQL schema; if unspecified, no schema is used in the SQL definitions (which corresponds to the public schema)

concise-sequelize

Output-only.

Output options:

  • Sequelize (Object): the Sequelize class
  • sequelize (Object): a Sequelize instance
  • extensions? (MapOf<ModelName, SequelizeExtensions>): object that associates a given model (or $all for all models) to a set of extensions (or customizations). Description to be completed (see typedefs and tests for the time being)


concise-flow

Output-only.

Output options:

  • file? (string): if specified, output will be written to the specified path

concise-graphql

Output-only.

Output options:

  • file? (string): if specified, output will be written to the specified path

  • storyboard? (boolean = false): include storyId field in mutation input types to support end-to-end Storyboard stories

concise-diagram

Output-only.

Output options:

  • file? (string): if specified, output will be written to the specified path
  • filterEdges? ({ from: ModelName, to: ModelName, as: FieldName, isRequired: boolean } => boolean): return true if a given edge must be shown. Default: all edges are shown
  • edgeLabels? (boolean = true): show edge labels

concise-firebase
