All <span class="notranslate">Rules</span> across Firebase products have a path-matching component and a conditional statement allowing read or write access. You must define <span class="notranslate">Rules</span> for each Firebase product you use in your app.</p> <p>For <span class="notranslate">Cloud Firestore</span> and <span class="notranslate">Cloud Storage</span>, <span class="notranslate">Rules</span> use the following syntax:</p> <pre class="prettyprint" translate="no" dir="ltr"><code translate="no" dir="ltr">service <<name>> { // Match the resource path. match <<path>> { // Allow the request if the following conditions are true. allow <<methods>> : if <<condition>> } } </code></pre> <p>For <span class="notranslate">Realtime Database</span>, JSON-based <span class="notranslate">Rules</span> use the following syntax:</p> <pre class="prettyprint" translate="no" dir="ltr"><code translate="no" dir="ltr">{ "rules": { "<<path>>": { // Allow the request if the condition for each method is true. ".read": <<condition>>, ".write": <<condition>> } } } </code></pre> <p><span class="notranslate">Rules</span> are applied as <code translate="no" dir="ltr">OR</code> statements, not <code translate="no" dir="ltr">AND</code> statements. Consequently, if multiple rules match a path, and any of the matched conditions grants access, <span class="notranslate">Rules</span> grant access to the data at that path. Therefore, if a broad rule grants access to data, you can't restrict with a more specific rule. You can, however, avoid this problem by making sure your <span class="notranslate">Rules</span> don't overlap too much. <span class="notranslate">Firebase Security Rules</span> flag overlaps in your matched paths as compiler warnings.</p> <p><span class="notranslate">Firebase Security Rules</span> can also leverage <span class="notranslate">Authentication</span> to grant user-based permissions, and the conditions you set can be very basic or incredibly complex.
