+# Migrating purser from flow-js to typescript
+
+this is a small diary of the migration process from flow to typescript
+
+
+Done with the help of this tutorial:
+https://medium.com/inato/migrating-from-flow-to-typescript-why-how-worth-it-5b7703d12089
+
+
+Current Strategy: Start with purser-core and then digging forward to other modules.
+
+
+## typescript config changes
+
+### dom Modules
+the dom module was required for using the crypto functionality of windows
+(Maybe it could be bypassed by using hashtable accessor (this['window'] instead of this.window))
+
+### esModuleInterop flag
+esModuleInterop is required for the BN.js library. see: https://github.com/CodeChain-io/codechain-primitives-js/issues/68
+
+
+### Internal references
+
+used to be `@colony/purser-core` - now they are `../purser-core`.
+need to figure out how to do better.
+
+
+## Known Issues
+
+### Removed Functionality
+
+- removed eslint for now, going to reactivate proper linting for TS later on.
+- genericWallet `otherAddresses` property and in the constructor ?? added again ?! TODO: check.
+
+
+## Possible Improvements
+
+## TransactionObjectType
+
+maybe TransactionObjectType could be replaced with the less restrictive eth-core type TransactionConfig,
+
+´´´
+export interface TransactionConfig {
+    from?: string | number;
+    to?: string;
+    value?: number | string | BN;
+    gas?: number | string;
+    gasPrice?: number | string | BN;
+    data?: string;
+    nonce?: number;
+    chainId?: number;
+}
+´´´
+
+### purser-software
+removed the setter purser-software keystore.
+
+set keystore(newEncryptionPassword: string): void {
+    internalEncryptionPassword = newEncryptionPassword;
+}
+
+#### Private Key is passed forward as Buffer
+see privateKeyBuffer, ethereum-js privateToPublic works only with buffers.
+
+#### Private Key from Mnemonic
+
+SoftwareWallet requires `WalletArgumentsType` as construction argument.
+In the old implementation an
+
+
+## Should be tested
+- support for msCrypto (Edge browser)
