pg-ts

Typescript wrapper around node-postgres

💥 breaking change 🚀 new feature 🐛 bug fix 🔧 chore 📓 docs

v10.0.0

• 🔧 Dependency updates

v9.0.3

• 🔧 improve PgDriverQueryError message

v9.0.2

• 🐛 If a queryOneOrNone was executed with SQL that selected insufficient columns to fully populate the row type, it would erroneously return None. Fixed now to return the expected PgRowValidationError type.

v9.0.1

• 🐛 Prevent array positional parameters from being deduped.

v9.0.0

• 💥 An additional context param has been added to connection.query and queryX functions. This is a blob of data that will be attached to query and transaction error instances. The normal use case for this is attaching application context so that error reporting functions can group errors together, or log out additional information about where the error came from.

v8.1.0

• 🚀 Add named function to set the name of a given SQL-templated query.

v8.0.1

• 🐛 Sql fragment parser should unwrap complex types (e.g. NonEmptyArray, Option) before passing it to the driver.

v8.0.0

• 🐛 Fix broken nominal typing on classes by changing public readonly _T = "<class name>" to public readonly _<class name>: void.
• 💥 As a result of fixing nominal typing, makeConnectionPool now returns an error union of PgPoolCreationError | PgTypeParserSetupError instead of PgPoolCreationError. Other errors may occur in application code as a result of the error classes now being correctly differentiated.

v7.0.0

• 💥 [email protected]
• 💥 [email protected]
• 💥 [email protected]

v6.0.1

• 🔧 Add _T symbol to uniquely identify error classes

v6.0.0

• 💥 Simplified the API by always requiring an environment object in which pg-ts can store it's state (Connection) under a Symbol key. This will never conflict with other keys in the E, so we can now remove ConnectionE and related subsequent design decisions.

v5.0.1

• 🐛 QueryAnyError union included PgRowCountError. This is incorrect (obvs).
• 🔧 Compiled with TS3.0.1.

v5.0.0

• Eitherish functions no longer return a simple Error type in their Lefts. Instead, we now provide a union of concrete error types that make it explicit what the failure conditions are. Clients can pattern match on error type using the provided ErrorPredicate functions, e.g, isRowCountError. Application-defined error types are propagated through the pg-ts stack.

• Commonly-grouped errors are provided as unions, e.g. ConnectionError<L>, TransactionError<L>.

• Renamed withConnectionE to widenToConnectionE for clarity and to differentiate from the withConnectionE function defined on Connection.

• withTransaction has been replaced by three similar functions that assist you depending on whether you want to go from:

  Outer Context	Inner Context	Function to use
  Connection	Connection	withTransactionC
  ConnectionE<E>	ConnectionE<E>	withTransactionE
  ConnectionE<E>	Connection	withTransactionEC

• Fixed the types setting in package.json, so imports should now default to from "pg-ts" instead of from "pg-ts/dist".

• Integration tests are provided. A DATABASE_URL environment variable must be present. The test suite will create the table it needs and will truncate before each test. Every query type is tested and transaction commit/rollback behaviour is also verified.
