The loader.mjs module exports the following functions that might help you write code that is portable to multiple consensus networks.

canonicalizeConnectorMode(string) => string

Expands a connector mode prefix to its full, canonical name. The canonical connector modes are:

getConnectorMode() => string

Returns the canonicalized connector mode, based on the process.env.REACH_CONNECTOR_MODE environment variable. If the variable is missing or empty, it will return the canonicalized form of 'ETH'.

getConnector() => string

Returns the first piece of getConnectorMode(), which indicates the abbreviated name of the network being connected to. Connectors are one of the following: ['ETH', 'ALGO'].

loadStdlib(env) => Promise<stdlib>

Returns a Promise for a stlib based on the provided env string or map. In environments where the reach stdlib has implicit access to process.env, you may omit the env argument, in which case process.env will be used.

If the reach stdlib is being used with javascript bundlers like webpack – as it is with React, for example – then the reach stdlib does not have implicit access to process.env. In such scenarios, we recommend that you call this function like so:

const reach = await loadStdlib(process.env);

You may instead pass in the string 'ETH' or the string 'ALGO' to select the desired stdlib directly.
