CLI config

pgtyped CLI can be launched in build or watch mode.
Watch mode is most useful for a local development workflow, while build mode can be used for generating types when running CI.

Flags

The CLI supports two flags:

  • -c config_file_path.json to pass the config file path.
  • -w to start in watch mode.
Example:
npx pgtyped -w -c config.json

Environment variables

PgTyped supports common PostgreSQL environment variables:

  • PGHOST
  • PGUSER
  • PGPASSWORD
  • PGDATABASE
  • PGPORT

These variables will override values provided in config.json.

Configuration file format

config.json
{
// You can specify as many transforms as you want
// Only TS and SQL files (modes) are supported at the moment
"transforms": [
{
"mode": "sql", // SQL mode
"include": "**/*.sql", // SQL files pattern to scan for queries
"emitTemplate": "{{dir}}/{{name}}.queries.ts" // File name template to save generated files
},
{
"mode": "ts", // TS mode
"include": "**/action.ts", // TS file pattern to scan for queries
"emitTemplate": "{{dir}}/{{name}}.types.ts" // File name template to save generated files
}
],
"srcDir": "./src/", // Directory to scan or watch for query files
"failOnError": false, // Whether to fail on a file processing error and abort generation (can be omitted - default is false)
"camelCaseColumnNames": false, // convert to camelCase column names of result interface
"db": {
"dbName": "testdb", // DB name
"user": "user", // DB username
"password": "password", // DB password (optional)
"host": "127.0.0.1" // DB host (optional)
}
}

Customizing generated file paths

By default, PgTyped saves generated files in the same folder as the source files it parses.
This behavior can be customized using the emitTemplate config parameter.
In that template, four parameters are available for interpolation: root, dir, base, name and ext.
For example, when parsing source/query file /home/user/dir/file.sql, these parameters are assigned the following values:

┌─────────────────────┬────────────┐
│ dir │ base │
├──────┬ ├──────┬─────┤
│ root │ │ name │ ext │
" / home/user/dir / file .sql "
└──────┴──────────────┴──────┴─────┘
(All spaces in the "" line should be ignored. They are purely for formatting.)
