pgsqwell

SQL template tag for PostgreSQL done well

Done well because:

immutable
separation of concerns / specialization: use the sql tag for valid SQL statements, sqlPart for subparts that ain't necessarily valid

Sample usage

import sql, {
  escapeSQLIdentifier,
  sqlPart,
  emptySQLPart,
  joinSQLValues,
} from 'pgsqwell';

const limit = 10;
const query = sql`SELECT id FROM users WHERE name=${'toto'} ${
  limit ? sqlPart`LIMIT ${limit}` : emptySQLPart
}`;
const query2 = sql`SELECT id FROM ${escapeSQLIdentifier('table')}`;
const query3 = sql`SELECT id FROM users WHERE id IN ${joinSQLValues([1, 2])}}`;
const mergedQuery = sql`
${query}
UNION
${query2}
UNION
${query3}
