TL;DR

esbuild now supports the proposed import text syntax, allowing direct import of text files as strings, and includes security improvements to its installation process.

Breaking

• Installation Integrity: esbuild now verifies the hash of downloaded binaries during installation, potentially impacting custom or unusual installation methods.
• Go Compiler Update: An internal Go compiler upgrade could introduce subtle behavioral changes, though unlikely.

New

• Import Text: You can now use import string from './example.txt' with { type: 'text' } to directly import text files (import text proposal).
• TypeScript Target: esbuild now supports the es2025 target in tsconfig.json files (TypeScript configuration).

Fixes Worth Knowing

• Async Generators: Corrected an issue with async generator transformations, resolving incorrect behavior with concurrent polling.
• Metafile Output: Fixed a regression where build errors weren’t correctly reported when metafile: true was enabled.
• TypeScript Parameter Properties: Improved handling of TypeScript parameter properties, generating class fields as expected.
