<p>Writes <code>msg.payload</code> to a file, either adding to the end or replacing the existing content.
|
|
Alternatively, it can delete the file.</p>
|

<h3>Inputs</h3>
|
|
<dl class="message-properties">
|
|
<dt class="optional">filename <span class="property-type">string</span></dt>
|
|
<dd>If not configured in the node, this optional property sets the name of the file to be updated.</dd>
|
|
</dl>
|
|
<h3>Details</h3>
|
|
<p>Each message payload will be added to the end of the file, optionally appending
|
|
a newline (\n) character between each one.</p>
|
|
<p>If <code>msg.filename</code> is used the file will be closed after every write.
|
|
For best performance use a fixed filename.</p>
|
|
<p>It can be configured to overwrite the entire file rather than append. For example,
|
|
when writing binary data to a file, such as an image, this option should be used
|
|
and the option to append a newline should be disabled.</p>
|
|
<p>Alternatively, this node can be configured to delete the file.</p>

<dt class="optional">error <span class="property-type">object</span></dt>

|
<dd><i>deprecated</i>: If enabled in the node, when the node hits an error
|
|
reading the file, it will send a message with no <code>payload</code>
|
|
and this <code>error</code> property set to the error details. This
|
|
mode of behaviour is deprecated and not enabled by default for new
|
|
instances of the node. See below for more information.</dd>
|
|
</dl>
|
|
<h3>Details</h3>
|
|
<p>The filename should be an absolute path, otherwise it will be relative to
|
|
the working directory of the Node-RED process.</p>
|
|
<p>On Windows, path separators may need to be escaped, for example: <code>\\Users\\myUser</code>.</p>
|
|
<p>Optionally, a text file can be split into lines, outputting one message per line, or a binary file
|
|
split into smaller buffer chunks - the chunk size being operating system dependant, but typically 64k (Linux/Mac) or 41k (Windows).</p>
|
|
<p>When split into multiple messages, each message will have a <code>parts</code>
|
|
property set, forming a complete message sequence.</p>
|
|
<h4>Legacy error handling</h4>
|
|
<p>Before Node-RED 0.17, if this node hit an error whilst reading the file, it would
|
|
send a message with no <code>msg.payload</code> and <code>msg.error</code> set to the
|
|
details of the error. This is a deprecated mode of behaviour for the node that new
|
|
instances will not do. If required, this mode can be re-enabled within the node
|
|
configuration.</p>
|
|
<p>Errors should be caught and handled using a Catch node.</p>
