parcel-query

A REPL to investigate the Parcel graphs in the cache ("offline", after the build).

Installation

Clone and run yarn, then cd packages/dev/query && yarn link to make the parcel-query binary globally available.

Usage

Call .help to view a list of commands.

In a project root containing a .parcel-cache folder:

$ parcel-query
> .findBundleReason 27494aebac508bd8 TJbGI
# Asset is main entry of bundle: false
# Asset is an entry of bundle: false
# Incoming dependencies contained in the bundle:
{
  id: '3fd182662e2a6fa9',
  type: 'dependency',
  value: {
    specifier: '../../foo',
    specifierType: 0,
...

In the .getAsset 3Xzt5 variant, no quotes/parenthesis are needed. Alternatively, you can use proper JS: getAsset("3Xzt5").

The variables assetGraph and bundleGraph contain the deserialized objects.

For a single query, the command (which has to be a JS call) can be specified as a CLI parameter (the disadvantage here is that the graphs have to be loaded on every call as opposed to once when starting the REPL):

$ parcel-query 'findBundleReason("b0696febf20b57ce", "bNAUZ")'
