while i try to run md5 for a file i get this erreur:

SyntaxError: expected expression, got '<' 

this is my code:

 let hasher = new ParallelHasher('ECHRI-ADMIN-WEB-APP/node_modules/ts-md5/dist             /md5_worker.js');
 hasher.hash(file);

how to solve it ?

Please publish new version from master to NPM

The ts-md5 version on npm is 1.2.2 but package.json says 1.2.0. Also, the code slightly differs. And there is no main entry in package.json in 1.2.2 on npm.

Kindly update document

I see there is a new version 1.2.10, it would to good to now what changed in this version

It would be great if this project could provide a changelog information (e.g. CHANGELOG.md, or using the github releases).

Since updates few days ago and especially this commit: 996cbd5#diff-2f043c58a6b511acb59702fd73ef287fR401

The following error came back again:

Uncaught ReferenceError: require is not defined
    at md5_worker.js:401
(anonymous) @ md5_worker.js:401

It seems to have been fixed in previous version following discussions here: #7

But the mentioned commit make require() and self._md5 = new md5_1.Md5(); reappear, leading to the error.

I'm trying to use this inside a Hardhat project which as far as I know doesn't have 'webworkers', so wondering if its possible to hasn a non text file like a .png.

Thanks.

Kindly upgrade ts-md5 to an ES module

When compiling, I receive the following errors:

node_modules/ts-md5/src/md5.ts(242,31): error TS2531: Object is possibly 'null'.
node_modules/ts-md5/src/md5.ts(243,31): error TS2531: Object is possibly 'null'.

node_modules/ts-md5/src/md5.ts(272,33): error TS7006: Parameter 'k' implicitly has an 'any' type.

I have update ts-md5 to 1.2.5. and get the error

Cannot find name 'WorkerOptions'.

constructor(workerUri: string, workerOptions?: WorkerOptions);

Method end has a specific case when it return undefined.

public end(raw: boolean = false) {
  // ...  
    const matches = dataBitsLen.toString(16).match(/(.*?)(.{0,8})$/);
      if (matches === null) {
        return;
       }
  // ...  
}
``

Maybe this case should raise an exception?

I want to calculate the checksum of 3 GB file blob. ParallelHasher took 5-7 min to calculate the checksum from the blob.

when i use rollup funciton in angular project,then i got an error, logs below:

...
Error: 'Md5' is not exported by node_modules\ts-md5\dist\md5.js
https://github.com/rollup/rollup/wiki/Troubleshooting#name-is-not-exported-by-module
...
then
i modofy file dist\md5.js
var Md5 ... to export var Md5
it works
yours

Hey, we wan't to use your project, but there is a licence missing in your project :)
Thanks a lot.

We can calculate md5 from blob,

import {ParallelHasher} from 'ts-md5/dist/parallel_hasher';
 
let hasher = new ParallelHasher('/path/to/ts-md5/dist/md5_worker.js');
hasher.hash(fileBlob).then(function(result) {
   console.log('md5 of fileBlob is', result);
});

If we can calculate MD5 from file path as well that will good.

I read it happened and was fixed before... well, here we are again:

The module on NPM includes a reference to md5.js.map.
I use webpack in my project to combine my own code with all modules in a single file. When I load this bundle afterwards in a browser, I get an error that md5.js.map couldn't be loaded (because I don't copy it to the output directory).
I just tried to fork the repo and solve it myself, but unfortunately all dependencies are set to latest and due to the change to TS 2.0 (at least I think this is the reason) the project currently can't be compiled successfully.

@stakach: What versions of your dependencies have you used the last time you successfully compiled the sources?

i am using ts-md5": "^1.2.4" and below is my environment

while executing the command ng serve i am getting the error as

ERROR in node_modules/ts-md5/dist/parallel_hasher.d.ts(6,52): error TS2304: Cannot find name 'WorkerOptions'.

and when i went to the particular file removed the workerOptions in constructor and it worked but this is not the solution
@stakach @skogsbaer @itsmontoya @johnbendi @qk4

I cloned the repo and copied dist/* to my Angular 4.4.6 application (both under node_modules/ts-md5/dist and src/assets). Then attempted to md5sum a file per the following snippet.

import { Md5 } from 'ts-md5/dist/md5';
import { ParallelHasher } from 'ts-md5/dist/parallel_hasher';
...
    for (let i = 0; i < this.filesToUpload.length; i++) {
      const fileReader = new FileReader();
      fileReader.onload = function(e : ProgressEvent) {
        let hasher = new ParallelHasher('assets/md5_worker.js');
        hasher.hash(fileReader.result)
          .then(function(result) {
            console.log('hash: ' + result);
          });
        const md5 = new Md5();
         md5.appendByteArray(fileReader.result);
        console.log("hash: " + md5.end()); // this isn't correct. 
      };
      fileReader.readAsBinaryString(this.filesToUpload[i]);

When running the app, Chrome's console shows:
ErrorEvent {isTrusted: true, message: "Uncaught ReferenceError: require is not defined", filename: "http://localhost:4200/assets/md5_worker.js", lineno: 401, colno: 13, …}

Line 401 of md5_worker.js corresponds to this statement:
`var md5_1 = require("./md5");

Is RequireJS meant to be a prerequisite of ts-md5?

As a secondary but related issue:
I had first tried using the latest version (v1.2.2) of ts-md5 from NPM. But it also failed with:
ErrorEvent {isTrusted: true, message: "Uncaught TypeError: Md5.Md5 is not a constructor", filename: "http://localhost:4200/assets/md5_worker.js", lineno: 417, colno: 21, …} Uncaught TypeError: Md5.Md5 is not a constructor at Md5FileHasher.hash (md5_worker.js:417) at global.onmessage (md5_worker.js:502)

Line 417 of md5_worker.js corresponds to:

    Md5FileHasher.prototype.hash = function (blob) {
        var self = this;
        self._blob = blob;
        self._length = Math.ceil(blob.size / self._partSize);
        self._part = 0;
        self._md5 = new Md5.Md5();   <---  FAILS HERE
        self._processPart();
    };

So md5_worker.js doesn't work whether it's from
a. the head of git: "Uncaught ReferenceError: require is not defined"
b. or NPM: "Uncaught TypeError: Md5.Md5 is not a constructor"

And FYI, the version on NPM is a few months out-of-date compared to git.

I'd appreciate any help getting the file hashing feature of ts-md5 operational in my app.

Thanks,
David

(Sorry for the earlier, empty post. I accidentally hit Enter just as I had started composing this).

Hi I am trying to use your library but I am unsure which method (hashString or hashAsciiString) to use.

What is the difference between:

Md5.hashString("foobar")
Md5.hashAsciiString("foobar")

and when to use which?

Thanks in advance!

Sometimes we need Uppercase HEX string as result and it will save a lot of lines.Can this function be added

SCRIPT5009: “Int32Array”未定义

Getting the exports is not defined error. Please add support for ESM imports.
