This page compares the source lines of code (SLOC) of nestjs/nest and expressjs/express using cached OctoCounts reports. Code size is not code quality: a larger count only means more source material, not a better or worse project.
As of 2026-08-31, nestjs/nest contains 122,036 total lines (101,193 code) across 1,922 files, while expressjs/express contains 9,400 total lines (2,617 code) across 70 files as of 2026-09-10. nestjs/nest is about 39x the size of expressjs/express by code lines. Code size is not code quality: a larger count only means more source material, not a better or worse project.

Top languages in nestjs/nest: TypeScript (68.4% of code), JSON (30.9% of code), JavaScript (0.2% of code). Top languages in expressjs/express: JavaScript (90.4% of code), JSON (3.8% of code), Handlebars (2.7% of code). JSON, JavaScript appear in both top language lists; TypeScript, GraphQL, YAML appear only in nestjs/nest's top languages; Handlebars, CSS, HTML appear only in expressjs/express's top languages.
Methodology: both counts come from cached OctoCounts reports generated with tokei. nestjs/nest was counted at ref master (commit 39fbddae5128) on 2026-08-31; expressjs/express was counted at ref master (commit bed501c695a6) on 2026-09-10. See the counting methodology for ignored directories and analysis options.
Evidence and next steps:
Note: code size is not code quality. OctoCounts only reports reproducible line counts and makes no claim that either project is better.
nestjs/nest has more code: 101,193 code lines versus 2,617 for expressjs/express, about 39x as much, based on cached OctoCounts reports as of 2026-09-10.
Not necessarily. SLOC measures size, not complexity, quality, or maintainability. A larger codebase can mean more features, more generated or vendored code, more verbose language idioms, or more tests — none of which imply the code is harder to work with. Use SLOC to gauge the scale of what you'd be reading or maintaining, not as a quality signal for nestjs/nest, expressjs/express, or any repository.
