Truffle(@next) does not find any migrations with .ts extension

[roderik]

It can be configured with https://github.com/trufflesuite/truffle/blob/46fc7bdb9fde7cc3fa99b94fef04b1d6c04c38f7/packages/truffle-migrate/index.js#L30 but I have not figured out how to set it

[roderik]

Workaround:

set migrations_directory: './dist', in truffle.js
add this to package.json scripts

    "build:truffle": "truffle compile",
    "build:contracts": "typechain --target truffle './build/contracts/*.json'",
    "build:ts": "tsc --declaration",
    "build": "npm run build:truffle && npm run build:contracts && npm run build:ts",

and run npm run build && truffle migrate

I use this tsconfig file

{
  "compilerOptions": {
    "module": "commonjs",
    "esModuleInterop": true,
    "target": "ES2017",
    "noImplicitAny": true,
    "suppressImplicitAnyIndexErrors": true,
    "moduleResolution": "node",
    "sourceMap": true,
    "outDir": "dist",
    "baseUrl": ".",
    "skipLibCheck": true,
    "paths": {
      "*": ["node_modules/*", "types/*"]
    }
  },
  "exclude": ["dist/**/*"]
}

My fix PR was merged in the latest truffle beta

While I can now select .ts files, it freaks out on imports

import { MigrationsContract } from '../types/truffle-contracts/index';
const Migrations: MigrationsContract = artifacts.require('./Migrations.sol');

const migration: Truffle.Migration = async (deployer: Truffle.Deployer) => {
  await deployer.deploy(Migrations);
};

module.exports = migration;

// because of https://stackoverflow.com/questions/40900791/cannot-redeclare-block-scoped-variable-in-unrelated-files
export {};

Without the MigrationsContract the artifacts.require returns an 'any' which does not help me at all in making my migrations strongly typed.

Using jsdoc comments might be a decent work around for now. You can still import the generated typings.

Example:

import {
  ConvertLibContract,
  MetaCoinContract
} from "../types/truffle-contracts";

/**
 * @type {ConvertLibContract}
 */
var ConvertLib = artifacts.require("./ConvertLib.sol");

/**
 * @type {MetaCoinContract}
 */
var MetaCoin = artifacts.require("./MetaCoin.sol");

[krzkaczor]

The problem with:

var ConvertLib = artifacts.require("./ConvertLib.sol");

is that you need to use artifact name like this instead:

var ConvertLib = artifacts.require("ConvertLib");

But anyway, I can't get it to work as files don't seem to be transpiled on the fly... I am not sure why. @roderik any ideas?
