Z-Brain TypeORM PostgreSQL Camelcase Naming Strategy

Pascal/Camel Case naming for everything in the PostgreSQL

Notice: If you have any propositions feel free to make an issue or create a pull request.

Features

• All constraint names appended with 8-char hash for uniqueness. Example: eed18e0e
• All names trimmed to 63 bytes including 8-char hash if the name is too long (in most cases length === bytes number, however not always).
• There is an ability to have some suffixes to entity classes and omit these suffixes in the DB table names.
  Example: PublicTradeEntity -> PublicTrades (default entity suffix is Entity)
• There is an ability to have some in-db suffixes on entity classes that should not be pluralized and should be added as is to the DB table names.
  Example: PublicTradeZipEntity -> PublicTradesZip (default in-db suffix is Zip)

Naming entity	Case	Examples
Table	PascalCase	Users, MySuperTable
Column	CamelCase	id, mySuperColumn
Enum	(not supported by TypeORM yet)
Primary Key	PK_{table}_{cols}_{hash}	PK_Instruments_id_bd441074, PK_MySuperTable_email,pwdHash_d1d1d1d1
Unique Constrain	UQ_{table}_{cols}_{hash}	UQ_Instruments_code_051d8d38, UQ_MySuperTable_firstName,lastName_d1d1d1d1
Default Constrain	DF_{table}_{col}_{hash}	DF_Users_email_d1d1d1d1, DF_MySuperTable_firstName_d1d1d1d1
Relation Constrain	REL_{table}_{cols}_{where}_{hash}	TODO example
Check Constrain	CHK_{table}_{expression}_{hash}	TODO example
Exclusion Constrain	XCL_{table}_{expression}_{hash}	TODO example
Foreign Key	FK_{table}_{targetTable}_{cols}_{targetCols}_{hash}	FK_TradingPairs_Instruments_quotedInstrumentId_id_fc68de3f
Index	IDX_{table}_{cols}_{hash}	IDX_Tickers_exchangeId,symbol_c8090854
Unique Index	UQIDX_{table}_{cols}_{hash}	UQIDX_Tickers_exchangeId,symbol_c8090854

// Store an instance separately for reuse methods in you app
export const typeORMNamingStrategy = new TypeORMPostgresCamelCaseNamingStrategy();

// TypeORM connection config for PostgreSQL
export const defaultConnection: ConnectionOptions = {
  // ...
  namingStrategy: typeORMNamingStrategy,
};

module.exports = [defaultConnection];
