pgtyped-rescript

This package provides the pgtyped-rescript CLI. The pgtyped-rescript CLI can work in build and watch mode.

Flags:

The CLI supports two flags:

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

Running the CLI:

npx pgtyped-rescript -w -c config.json

Env variables:

PgTyped supports common PostgreSQL environment variables:

• PGHOST
• PGUSER
• PGPASSWORD
• PGDATABASE
• PGPORT

These variables will override values provided in config.json.

Config file:

Config file format (config.json):

{
  // You can specify as many transforms as you want
  // ReScript and SQL files are supported.
  "transforms": [
    {
      "mode": "sql", // SQL mode
      "include": "**/*.sql", // SQL files pattern to scan for queries
      "emitTemplate": "{{dir}}/{{name}}__queries.res" // File name template to save generated files
    },
    {
      "mode": "res", // ReScript mode
      "include": "**/*.res", // ReScript files pattern to scan for embedded SQL
      "emitTemplate": "{{dir}}/{{name}}__sql.res" // 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)
  }
}

Generated files

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.)

This package is part of the ReScript fork of PgTyped. Refer to the root README for details.
