# Aider chat conversation:
USER: if the fetch fails, skip the rest
ASSISTANT: To handle fetch failures, we need to modify the `share/index.md` file. We will add a `.catch` block to the fetch promise chain to handle any errors that occur during the fetch operation.
Here is the proposed change:
```markdown
share/index.md
<<<<<<< ORIGINAL
fetch(conv)
.then(response => response.text())
.then(markdown => {
// Ensure every line that starts with '>' ends with exactly 2 spaces
markdown = markdown.split('\n').map(function(line) {
if (line.startsWith('>')) {
return line.trimEnd() + ' ';
}
return line;
}).join('\n');
var html = marked.parse(markdown);
var divElement = document.querySelector('.chat-transcript');
divElement.innerHTML = html;
});

}

var html = marked.parse(markdown);
var divElement = document.querySelector('.chat-transcript');
divElement.innerHTML = html;
})
.catch(error => {
console.error('Error fetching markdown:', error);
});
>>>>>>> UPDATED
```
This change adds a `.catch` block to the fetch promise chain. If an error occurs during the fetch operation, the error will be logged to the console and the rest of the script will be skipped.
# Aider chat conversation:
USER: check to make sure there is a mdurl param, skip the rest if not
ASSISTANT: To implement this change, we need to modify the `share/index.md` file. We will add a condition to check if the `mdurl` parameter exists before proceeding with the rest of the script.
Here is the proposed change:
```markdown
share/index.md
<<<<<<< ORIGINAL
window.onload = function() {
var urlParams = new URLSearchParams(window.location.search);
var conv = urlParams.get('mdurl');
fetch(conv)
=======
window.onload = function() {
var urlParams = new URLSearchParams(window.location.search);
var conv = urlParams.get('mdurl');
if (!conv) {
return;
}
fetch(conv)
>>>>>>> UPDATED
```
This change checks if `conv` (which holds the value of the `mdurl` parameter) is not present. If it's not, the function returns immediately, skipping the rest of the script.
# Aider chat conversation:
USER: also load https://cdn.jsdelivr.net/npm/marked/marked.min.js
ASSISTANT: To load the `marked.min.js` library from the CDN, we need to add a script tag in the `index.md` file. Here is the change:
```markdown
share/index.md
<<<<<<< ORIGINAL
<script>
window.onload = function() {
=======
<script src="https://cdn.jsdelivr.net/npm/marked/marked.min.js"></script>
<script>
window.onload = function() {
>>>>>>> UPDATED
```
This change adds a new script tag before the existing script tag. The new script tag loads the `marked.min.js` library from the CDN. The existing script tag remains unchanged.
