Packages Compared

Criteria

Validation

These packages are capable of validating the data for type correctness.

E.g. if string was expected, but a number was provided, the validator should fail.

Interface

It has a validator function or method that returns a valid type casted value or throws.

const data: any = {}

// `res` is now type casted to the right type
const res = isValid(data)

Or it has a type guard function that in a truthy block type casts the value.

const data: any = {}

function isMyDataValid(data: any) {
  // isValidGuard is the type guard function provided by the package
  if (isValidGuard(data)) {
    // data here is "guarded" and therefore inferred to be of the right type
    return data
  }

  throw new Error('Invalid!')
}

// `res` is now type casted to the right type
const res = isMyDataValid(data)

Local Development

npm run start - run benchmarks for all modules
npm run start run zod myzod valita - run benchmarks only for a few selected modules
npm run docs:serve - result viewer
npm run test - run tests on all modules

Adding a new node version

update node version matrix in .github/workflows/pr.yml and .github/workflows/release.yml
update NODE_VERSIONS in docs/dist/app.tsx and run npm run docs:build
optionally set NODE_VERSION_FOR_PREVIEW in benchmarks/helpers/main.ts

Test cases

Safe Parsing
- Checks the input object against a schema and returns it.
- Raises an error if the input object does not conform to the schema (e.g., a type mismatch or missing attribute).
- Removes any extra keys in the input object that are not defined in the schema.
Strict Parsing
- Checks the input object against a schema and returns it.
- Raises an error if the input object does not conform to the schema (e.g., a type mismatch or missing attribute).
- Raises an error if the input object contains extra keys.
Loose Assertion
- Checks the input object against a schema.
- Raises an exception if the input object does not match the schema.
- Allows extra keys without raising errors.
- Returns true if data is valid.
Strict Assertion
- Checks the input object against a schema.
- Raises an exception if the input object does not match the schema.
- Raises an error if the input object or any nested input objects contain extra keys.
- Returns true if data is valid.
