dbt YAML validator using JSON Schema

JSON Schema is a way to define the expected shape of JSON (or YAML) documents. This enables live checking of your files, as well as Intellisense/autocomplete as you type.

What does it do?

This repository contains schemata for:

• Project definition files (dbt_project.yml)
• Package files (packages.yml)
• Selectors files (selectors.yml)
• Property files (models/whatever.yml)

Installation in VS Code

1. Install the VSCode-YAML extension
2. Inside of your dbt project's directory, create a .vscode/settings.json file containing the following data. This is what tells the extension which schema to associate with each file.

   {    
   "yaml.schemas": {
       "https://raw.githubusercontent.com/dbt-labs/dbt-jsonschema/main/schemas/latest/dbt_yml_files-latest.json": [
           "/**/*.yml",
           "!profiles.yml",
           "!dbt_project.yml",
           "!packages.yml",
           "!selectors.yml",
           "!profile_template.yml"
       ],
       "https://raw.githubusercontent.com/dbt-labs/dbt-jsonschema/main/schemas/latest/dbt_project-latest.json": [
           "dbt_project.yml"
       ],
       "https://raw.githubusercontent.com/dbt-labs/dbt-jsonschema/main/schemas/latest/selectors-latest.json": [
           "selectors.yml"
       ],
       "https://raw.githubusercontent.com/dbt-labs/dbt-jsonschema/main/schemas/latest/packages-latest.json": [
           "packages.yml"
       ]
   },
   }

3. To prompt other users to install the YAML extension, create a .vscode/extensions.json file containing the following data inside of your dbt project's directory:

   {
   "recommendations": [
       "redhat.vscode-yaml"
   ]
   }

Installation in Vim

1. Install the coc.nvim plugin
2. Install coc-yaml: :CocInstall coc-yaml
3. Add JSON Schema (there might be a better way to do this, but adding directly to coc-settings.json using :CocConfig works):

   {    
   "yaml.schemas": {
       "https://raw.githubusercontent.com/dbt-labs/dbt-jsonschema/main/schemas/latest/dbt_yml_files-latest.json": [
           "/**/*.yml",
           "!profiles.yml",
           "!dbt_project.yml",
           "!packages.yml",
           "!selectors.yml",
           "!profile_template.yml"
       ],
       "https://raw.githubusercontent.com/dbt-labs/dbt-jsonschema/main/schemas/latest/dbt_project-latest.json": [
           "dbt_project.yml"
       ],
       "https://raw.githubusercontent.com/dbt-labs/dbt-jsonschema/main/schemas/latest/selectors-latest.json": [
           "selectors.yml"
       ],
       "https://raw.githubusercontent.com/dbt-labs/dbt-jsonschema/main/schemas/latest/packages-latest.json": [
           "packages.yml"
       ]
   },
   }

Installation in JetBrains

IDEs by JetBrains like PyCharm and IntelliJ enable us to use the JSON Schema, using the JSON schema mapping feature.

1. Open the preferences of JSON schema mapping in JetBrains
2. Add custom schema mappings

There is no way to add the preferences with a configuration file like VS Code. As we have to manually configure them one by one, we just describe values of the configurations below. If you want to know the details, the dbt YAML validator in JetBrains article describes how to configure the JSON schema mapping in details.

• Project definition files
  • URL: https://raw.githubusercontent.com/dbt-labs/dbt-jsonschema/main/schemas/latest/dbt_project-latest.json
  • Schema version: JSON schema version 7
  • Mapping: dbt_project.yml
• Package files
  • URL: https://raw.githubusercontent.com/dbt-labs/dbt-jsonschema/main/schemas/latest/packages-latest.json
  • Schema version: JSON schema version 7
  • Mapping: packages.yml
• Selectors files
  • URL: https://raw.githubusercontent.com/dbt-labs/dbt-jsonschema/main/schemas/latest/selectors-latest.json
  • Schema version: JSON schema version 7
  • Mapping: selectors.yml
• Property files
  • URL: https://raw.githubusercontent.com/dbt-labs/dbt-jsonschema/main/schemas/latest/dbt_yml_files-latest.json
  • Schema version: JSON schema version 7
  • Mapping: models/**/*.yml, analysis/**/*.yml, snapshots/**/*.yml

Do you use a different IDE which also supports JSON Schema? Please open a PR with setup instructions and links to any extensions!

PRs that improve these schemata are welcome!

Please ensure that JSON keys are sorted by vscode-sort-json according to the rules in .vscode/settings.
