From 511ef87d69ea19d0ebbc4573d8d0690d1747cfb7 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 5 Nov 2025 08:27:30 +0000 Subject: [PATCH 1/2] Major improvements and new features CSV Parser: - Replace custom CSV parser with papaparse library - Better handling of malformed CSV files - Proper handling of missing/undefined values New API Methods: - Add getTripsByDate() to get all trips for a given date - Add getStopsByTrip() to get stops for a trip (ordered by sequence) - Add getTripsByService() for internal use Data Loading: - Fix ZIP loader to properly detect local file paths vs URLs - Improve error handling for undefined values in CSV data - Better type conversion handling for missing columns Tests: - Add comprehensive sample feed tests using Google's official GTFS example - Include sample-feed.zip (Apache 2.0 licensed) in test fixtures - Add README with proper attribution for sample feed - All 59 tests passing Documentation: - Add contact email (contact@sys-dev-run.fr) - Add website (https://www.sys-dev-run.fr/) - Update API documentation Dependencies: - Add papaparse for robust CSV parsing - Add @types/papaparse for TypeScript support All tests pass, linting passes, TypeScript compiles successfully. --- README.md | 3 + package-lock.json | 18 ++ package.json | 2 + src/gtfs-sqljs.ts | 20 ++- src/loaders/csv-parser.ts | 84 +++------- src/loaders/data-loader.ts | 3 +- src/loaders/zip-loader.ts | 29 ++-- src/queries/stops.ts | 22 +++ src/queries/trips.ts | 22 +++ tests/fixtures/README.md | 38 +++++ tests/fixtures/sample-feed.zip | Bin 0 -> 3217 bytes tests/sample-feed.test.ts | 296 +++++++++++++++++++++++++++++++++ 12 files changed, 460 insertions(+), 77 deletions(-) create mode 100644 tests/fixtures/README.md create mode 100644 tests/fixtures/sample-feed.zip create mode 100644 tests/sample-feed.test.ts diff --git a/README.md b/README.md index cb0d530..083e268 100644 --- a/README.md +++ b/README.md @@ -6,6 +6,9 @@ A TypeScript library for loading GTFS (General Transit Feed Specification) data **Théophile Helleboid / SysDevRun** +- Email: contact@sys-dev-run.fr +- Website: https://www.sys-dev-run.fr/ + ## Features - ✅ Load GTFS data from ZIP files (URL or local path) diff --git a/package-lock.json b/package-lock.json index a7c45fb..1dc7aef 100644 --- a/package-lock.json +++ b/package-lock.json @@ -10,10 +10,12 @@ "license": "MIT", "dependencies": { "jszip": "^3.10.1", + "papaparse": "^5.5.3", "sql.js": "^1.10.3" }, "devDependencies": { "@types/node": "^20.11.5", + "@types/papaparse": "^5.5.0", "@types/sql.js": "^1.4.9", "@typescript-eslint/eslint-plugin": "^6.19.0", "@typescript-eslint/parser": "^6.19.0", @@ -1111,6 +1113,16 @@ "undici-types": "~6.21.0" } }, + "node_modules/@types/papaparse": { + "version": "5.5.0", + "resolved": "https://registry.npmjs.org/@types/papaparse/-/papaparse-5.5.0.tgz", + "integrity": "sha512-GVs5iMQmUr54BAZYYkByv8zPofFxmyxUpISPb2oh8sayR3+1zbxasrOvoKiHJ/nnoq/uULuPsu1Lze1EkagVFg==", + "dev": true, + "license": "MIT", + "dependencies": { + "@types/node": "*" + } + }, "node_modules/@types/semver": { "version": "7.7.1", "resolved": "https://registry.npmjs.org/@types/semver/-/semver-7.7.1.tgz", @@ -3057,6 +3069,12 @@ "integrity": "sha512-4hLB8Py4zZce5s4yd9XzopqwVv/yGNhV1Bl8NTmCq1763HeK2+EwVTv+leGeL13Dnh2wfbqowVPXCIO0z4taYw==", "license": "(MIT AND Zlib)" }, + "node_modules/papaparse": { + "version": "5.5.3", + "resolved": "https://registry.npmjs.org/papaparse/-/papaparse-5.5.3.tgz", + "integrity": "sha512-5QvjGxYVjxO59MGU2lHVYpRWBBtKHnlIAcSe1uNFCkkptUh63NFRj0FJQm7nR67puEruUci/ZkjmEFrjCAyP4A==", + "license": "MIT" + }, "node_modules/parent-module": { "version": "1.0.1", "resolved": "https://registry.npmjs.org/parent-module/-/parent-module-1.0.1.tgz", diff --git a/package.json b/package.json index eb432f7..14a4a61 100644 --- a/package.json +++ b/package.json @@ -41,10 +41,12 @@ }, "dependencies": { "jszip": "^3.10.1", + "papaparse": "^5.5.3", "sql.js": "^1.10.3" }, "devDependencies": { "@types/node": "^20.11.5", + "@types/papaparse": "^5.5.0", "@types/sql.js": "^1.4.9", "@typescript-eslint/eslint-plugin": "^6.19.0", "@typescript-eslint/parser": "^6.19.0", diff --git a/src/gtfs-sqljs.ts b/src/gtfs-sqljs.ts index eb24844..74e9474 100644 --- a/src/gtfs-sqljs.ts +++ b/src/gtfs-sqljs.ts @@ -8,7 +8,7 @@ import { loadGTFSZip } from './loaders/zip-loader';
