No declaration file found in TypeScript/VS Code

[weber-d]

Using a TypeScript 2.8.1 project in VS Code 1.22.2, I got the error

src/main.ts(23,24): error TS7016: Could not find a declaration file for module 'couchdb-expression'. 'node_modules/couchdb-expression/lib/index.js' implicitly has an 'any' type.
Try npm install @types/couchdb-expression if it exists or add a new declaration (.d.ts) file containing declare module 'couchdb-expression';

when importing the module in line

import Expression from "couchdb-expression";

Sadly, it seems that no typings-package exist. Also the declare module line cause another error, that "couchdb-expression" was resolved in a not-typed module.

I also tried

import { Expression } from "couchdb-expression";
import * as Expression from "couchdb-expression";
import Expression = require("couchdb-expression");
const Expression = require("couchdb-expression");

Only the last one const Expression = require("couchdb-expression"); doesn't show me an error in VS Code. But after compiling, I get

error TS7016: Could not find a declaration file for module 'couchdb-expression'. 'node_modules/couchdb-expression/lib/index.js' implicitly has an 'any' type.

So it seems completely unusable with TS...

I have to apologize for my late response, and my badly documented repository.

Typescript support is something I will need to implement in the future, but for now, the module can be imported like such:

const session = require('express-session');
const Expression = require('couchdb-expression')(session);

Sorry for all the trouble!
