ESLint plugin which disallows each ECMAScript syntax.
Espree, the default parser of ESLint, has supported ecmaVersion
option.
However, the error messages of new syntax are not readable (e.g., "unexpected token" or something like).
When we use this plugin along with the latest ecmaVersion
option value, it tells us the readable error message for the new syntax, such as "ES2020 BigInt is forbidden."
Plus, this plugin lets us disable each syntactic feature individually.
See documentation
This plugin follows semantic versioning and ESLint's semantic versioning policy.
- We will release a new minor version to add new rules when TC39 decided to advance proposals to Stage 4. In the minor releases, we don't update configs.
- We will release a new major version to update configs when new ECMAScript snapshots are available.
See releases.
