JSQ - A mongoDB query parser for SQL databases

JSQ allows the use of similar mongoDB query expressions to find records in traditional SQL databases like Postgres, MySQL etc.

Installation

go get github.com/ncodes/jsq

Example

jsq, err := NewJSQ([]string{
    "valid_field_1",
    "name",
    "age",
})

// Parse a query
err := jsq.Parse(`{
    "name": { 
        "$eq": "ben" 
    }
}`)
if err != nil {
    log.Fatalf("failed to parse: %s", err)
}

// Get SQL 
sql, args, err := jsq.ToSQL()
