## API

### var dg = graph(levelup)

creates a new graph from a levelup

### Range Options

Various methods use these options for specifying ranges in the graph:

**since** - array of nodes to begin the range
**until** - array of nodes to end the range

### dg.count(opts, cb)

Get the total number of nodes between a range. Calls `cb` with the node count for the range you specify

`opts` should be Range Options.

### dg.match(hashes, cb)

Given an array of hashes, calls `cb` with the hashes that exist in the local graph

### dg.heads(cb)

Calls `cb` with an array of the current heads of the graph

### dg.createReadStream(opts)

Returns a readable stream that will emit graph nodes. `opts` should be Range Options

### dg.createWriteStream()

Returns a writable stream that stores data in the graph

### dg.get(key, cb)

Gets the value for a key in the graph, calls `cb` with the value

### dg.append(value, cb)

Appends `value` to the current head, calls `cb` when done. Uses `.add` internally.

### dg.add(links, value, cb)

Inserts `value` into the graph as a child of `links`, calls `cb` when done.

### dg.close(cb)

Calls close on the underlying `dg.db`

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.
