[Typescript] export = and import = require()
https://www.typescriptlang.org/docs/handbook/modules.html#export--and-import--require
When you export using `export = `
let numberRegexp = /^[0-9]+$/;
class ZipCodeValidator {
isAcceptable(s: string) {
return s.length === 5 && numberRegexp.test(s);
}
}
export = ZipCodeValidator;
Then to import those module you have to do `import = require()`
import zip = require("./ZipCodeValidator");
// Some samples to try
let strings = ["Hello", "98052", "101"];
// Validators to use
let validator = new zip();
// Show whether each string passed each validator
strings.forEach((s) => {
console.log(
`"${s}" - ${validator.isAcceptable(s) ? "matches" : "does not match"}`
);
});
