lsif-sqlite

library0.5.3jsnpmunverified

Converts LSIF (Language Server Index Format) dumps into SQLite databases for querying code intelligence data offline. Stable version 0.5.3, part of the lsif-node project by Microsoft. Accepts LSIF input files and produces a SQLite DB enabling efficient multi-file analysis. Differentiated from other LSIF tools by its focus on SQL persistence rather than in-memory processing.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

main

✓ import { lsifSqlite } from 'lsif-sqlite'

✗ const lsifSqlite = require('lsif-sqlite')

ESM-only; CJS require will fail. The package exports a main function.

convertToDb

✓ import { convertToDb } from 'lsif-sqlite'

✗ import convertToDb from 'lsif-sqlite'

Named export, not default.

transform

✓ import { transform } from 'lsif-sqlite'

✗ const transform = require('lsif-sqlite').transform

Named export; available only in ESM context.

LSIFDatabase

✓ import { LSIFDatabase } from 'lsif-sqlite'

✗ import LSIFDatabase from 'lsif-sqlite'

TypeScript type export; for type annotations only.

Converts an LSIF dump file stream into a SQLite database using the main convertToDb function.

import { convertToDb } from 'lsif-sqlite'; import { createReadStream } from 'fs'; import { open } from 'sqlite'; import sqlite3 from 'sqlite3'; async function main() { const lsifInput = createReadStream('dump.lsif'); const db = await open({ filename: 'output.db', driver: sqlite3.Database }); await convertToDb(lsifInput, db); console.log('Conversion complete'); await db.close(); } main().catch(console.error);

Debug

Known issues

breakingIn version 0.4.0, the API changed from callback-based to promise-based. Old code using callbacks will break.

fix

Use async/await or .then() with the new API.

affects: >=0.4 <0.5

deprecatedThe 'transform' function is deprecated in 0.5.0; use 'convertToDb' instead.

fix

Replace transform() with convertToDb() for new code.

affects: >=0.5

gotchaThe package expects LSIF v1.0 format. Using older or newer versions may cause parsing errors.

fix

Ensure LSIF dump is compatible with LSIF v1.0 specification.

affects: >=0.3

gotchasqlite3 native module may fail to build on some Node versions. Pre-built binaries are not provided.

fix

Install build tools (python, make, g++) or use 'sql.js' as an alternative.

affects: all

gotchaLarge LSIF dumps (>500MB) may cause out-of-memory errors because the entire input is loaded into memory before processing.

fix

Use streaming and chunking manually, or split the LSIF dump into smaller parts.

affects: all

Errors

Common errors & fixes

Error: Cannot find module 'lsif-sqlite'

Package not installed or not in node_modules.

fix

Run 'npm install lsif-sqlite' in your project directory.

TypeError: (0 , lsif_sqlite.convertToDb) is not a function

Incorrect import syntax (CommonJS require used with ESM-only package).

fix

Use 'import { convertToDb } from 'lsif-sqlite'' in an ESM context (type: module in package.json or .mjs file).

Error: SQLITE_ERROR: no such table: meta

The SQLite database schema is not created or is outdated.

fix

Ensure you use the latest version of the package and run the conversion on a fresh database.
