The compiler is a set of modules designed to extract GraphQL documents from across a codebase, transform/optimize them, and generate build artifacts..
A compiler is a special program that translates a programming language's source code into machine code, bytecode or another programming language.
The source code is typically written in a high-level, human-readable language such as Java or C++..
The compiler has two modules namely the front end and the back end.
Front-end constitutes the Lexical analyzer, semantic analyzer, syntax analyzer, and intermediate code generator.
And the rest are assembled to form the back end.
Lexical Analyzer – It is also called a scanner.Apr 18, 2023.
The compiling stage is organized in three components: the Parser, the Semantic Validator and the Object Code Generator, as shown in fig. 8.
With this architecture other programming languages can be easily plugged by simply implementing a parser which analyses that specific language and generates the same IR..

The next step is syntax analysis, where the compiler’parser checks the code for syntax errors and ensures that it follows the rules of the programming language.
The compiler generates an Abstract Syntax Tree (AST) that represents the structure of the code.
The Structure of a Compiler Almost all modern compilers are syntax-directed:
